Hands down the best service we've ever had (refreshing after our tenure with Priority Services).

We called up and had an appointment for routine maintenance within 2 days. Sierra AC and Heating sent out an astute technician named Josue who was not only friendly but also very knowledgeable. Professional, respectable, courteous, proficient, and an expert in putting technical terms into words we could understand are all adjectives I would use to describe him. I could tell he knew what he was doing and had integrity. He didn't try to pressure us with any sale or service. After talking with him for a few min, I discovered how proud he was of the work he does. He told me it's my passion and was very proud to be coming upon his 5 year anniversary in his job.

Thank you for your customer service, quickness, and professionalism. Prices are not that bad either!

I have never worked with a more disrespectful and unprofessional company than this company. The contractor showed up and could not find anything wrong with out unit even though it was leaking water all over the floor. After we pointed out the problem to him, he wrote up a work order that was very vague. Before he left my house, I was told that someone would get back to me within a couple of days with updates on what will be fixed. I just heard back today after almost two weeks. I called to ask for an update, only to be told that calling would slow down the process and that I should refrain from doing so. Maybe if they had communicated effectively this issue would not have happened. I am still without a working air conditioner and am going to request services elsewhere.

DON'T LET THEM PRESSURE YOU!
My AC quit working over the weekend. I had hired Sierra to do semiannual checkups, so I called them for help. A repairman was here quickly (late Saturday afternoon) and after 5-10 minutes told me it was dead and needed to be replaced. He called a salesman to give me a price on replacement. He also arrived quickly. After another 5-10 minutes he offered me a contract for $17,000 to replace the AC and heating unit with the promise they would do it Monday am. I was pressured to sign immediately to get it scheduled.

$17,000. I asked for time. I had purchased the AC unit just 5 years ago - so I checked to see if I was in warranty and called the company who had sold it to me. That company came out Monday am and repaired the unit in a couple hours for $1200. It was a simple leak of the coolant and he patched the hole.

I would never trust Sierra again. It's pretty low to stalk a widow for a big sale when a repair was all that was needed.

The company installed our new system in December. The technicians seem to know what they are doing and do it well, finding a problem that was as old as the house. For the summer service I appreciate the call in advance of arrival time which means not having to wait during the entire window. For the summer service, after the technician came to the house without the proper ladder for a system they installed, I wrote a negative review. The next day I received a call from the service manager who apologized, said the location was now noted in the record and compensated me for having to be home for a wasted visit. Wow!

John and Vincent were outstanding. They did an excellent job on reviewing all three of my systems. They took pictures and made recommendations so that I could see what my immediate threats are to my system.

Thank you Sierra Air Conditioning and Heating! I can always count on you to keep my system working properly throughout the entire year.

I'd be very careful using this company. I recently had an issue with my tankless water heater and called for someone to come out.

1) I took the day off of work to meet with them and of course they didn't show up for the 12 to 5pm window. Apparently, they accidently dispatched someone who didn't have tankless water heater experience and then recalled them. They finally showed up at about 9PM. I can live with that.

2) The tech was friendly and knowledgeable however it was quickly apparent that they were interested in up-sales rather than fixing my 2017 tankless water heater.

3) When the quotes came is, everything was a lump sum. The includes list included numerous items that I didn't need because since I already have a tankless water heater I wouldn't need. EX Install a gas line to the unit, install a water line etc.

When I asked them to remove the items that were not needed and to break down the cost estimate into parts and labor, they refused. This tells me they are gouging.

Just a little idea of how much, the quote was for $9500. To purchase a new tankless water heater was $1700. That means they were looking to collect $7800 in labor for plumbing 2 water connections, 2 air connections, 1 gas connection and a drain-line WHICH WERE ALREADY PLUMBED TO THE LOCATION.

Don't do it! They're crooks!

I contracted these fellows to do the maintenance program and that cost us $300 in March when they had to come look at our system and had an issue with the AC. The AC condenser had just been replaced and that cost us $1,000. I don't live in a large home it's 1700 square feet and built 2011. we've lived here two years. In that amount of time we have fixed the AC, have contracted these guys to perform maintenance the past year for $300, and now a week and a half ago they came out to look into the maintenance for the shift of winter because my heater wasn't coming on and told me I needed a new motor... that cost us another $1,000. This morning I wake up and my heater is doing the EXACT SAME THING that made me call them to do the maintenance check in March, and in November. It is freezing their phone is busy the online number automatically hangs up it's inaccurate. They never gave us a receipt for the transaction two weeks ago. I am still waiting to get a hold of them so we will see how this ends... But overall very disappointed and out alot of money during the holidays.

Update- Their phones were down, i went to their physical location to get someone over to fix our frigid home. Met with the gentleman who owns the place, glad that he actually met with me... and after the meet, he did get someone down to fix our unit the same day. He just followed up via email to get me the newer invoice from 11/30. Feeling better about the customer service so updating to 3 stars. Will have to see what the future brings. Still feel funny that this is the same issue repeating itself and we have poured over 2K into this issue... and the guy who came over today said he couldn't even figure out what went wrong and just reset it.

I purchased a Groupon for their Tune-Up service thinking I was doing the right thing even through my AC units was running perfectly, 4 weeks later my AC is out!!! I don't think this was a coincidence, I'm sure something was done to my unit to make it fail. You've been warned!

Sierra Air Conditioning and Heating came to our property rental in Summerlin because the fan and a couple of other parts on the outside unit broke. The technician recommended that we purchase a whole new unit for the house. We decided to replace the broken parts on the outside unit for $1400 since the cost is less than a whole new unit. About a week later the whole Air Conditioning unit crashed on us. Another technician came and checked it out. He said that we had to replace the whole air conditioning system. He did not just recommend it, he said we had to replace it. He went into the attic and found the complete problem. The first technician recommended a whole new system but he never went into the attic to find the complete problem. If he had then he would have told us what the second technician found and told us it had to be replaced not just recommended.

We contacted management with Sierra to see if they would give us $1400 credit towards a new unit with them or give us a refund if we went with another company. Sierra informed us that they would only give us half of the $1400 for credit if we got the new unit from them. If we went with another company then they would give us no refund at all.

This is extremely poor customer service. Also, we are clients of the company which services our residence we live at twice a year. I doubt we will continue that service. My wife and I decided to go with another company for our new air conditioning unit. Sierra is extremely overpriced for their new units. We saved thousands of dollars with another company. People should get other quotes before going with Sierra. We would not recommend Sierra Air Conditioning and Heating to relatives, friends or acquaintances.

Fantastic service. The tech - Frank came over and performed a system inspection. My A/C had not been looked at or tuned in over 10 years. Miraculously it was still operating but one of the electric motors was extremely hot. The bearings were shot and it needed to be replaced or we would have a surprise repair coming some time soon. With hot weather in the mix I wasn't going to take the risk. Fast service. Thank you!!!!

Sierra was great! I provided my contact information and service request online, received a call back the same day, scheduled a service technician to come out, recieved calls and text messages to update me on the arrival status of my technician, and got my HVAC unit back working after having no heat for 2 or 3 days. Again, all this happened same day! Thank you Sierra.

I must add that my service technician, Tunde was great. He was so polite first and foremost. He was able to identify the problem with my unit quuckly, explain the problem to me clearly, and get it all fixed. I definitely would recommend Sierra and Tunde to my friends and family. Thank you Sierra! Thank you Tunde!

Matt Dodson was my technician to trouble shoot a cooling problem discovered firing a Summer maintenance tune up.

He was very knowledgeable of air conditioning technology and how to trouble shoot problems.

He contacted second level technical support to confirm problem at my request.

Sierra Air Conditioning had parts and tools in the truck to enable their technician fix problem on site.

Matt Dodson, technician was friendly and answered all my questions. I would request Matt in the future should the need arise.

These guys are great! They have been taking care of our HVAC and tankless water heater since the house was built 2 1/2 years ago.

They have a great maintenance plan for $16 a month that includes two annual maintenance services plus a variety of other discounts and benefits.

They are always on time and genuinely professional and friendly. They are masked during COVID times and wear booties to protect your carpet and put down a pad to protect your floor when they setup their ladder.

They always do a comprehensive check of the heating system during the winter and on the cooling system in the summer. They check various components and have made suggestions to upgrade and protect the system which we've taken advantage of such as installing upgraded air filtration system.

Today Fabian Pantoja completed our winter maintenance and did a great job. He was right on schedule and super friendly and professional. He did a comprehensive inspection and made some suggestions to protect the system such as a hard start kit and a more through cleaning. These were very low pressure suggestions that made sense to me. I expected him to have to return another day, but he took care of all the extra work the same day and was done within two hours or so.

They come once a year and do routine maintenance on the tankless water heater as well. This is always similarly an efficient and friendly experience.

I have always been pleased with Sierra, and I highly recommend them and specifically recommend their maintenance agreement. You don't want your AC to quit in Las Vegas in summer!

My only slight piece of feedback would be that they don't seem to proactively reach out to schedule your routine maintenance visits. I have always had to call myself, and then they're usually scheduling over a month (or more) out. This makes it hard to actually complete the heating or cooling maintenance before the heating or cooling season is in full swing.

In 2015 I had to replace the two 17 yr old A/C units when we moved into our home. I chose Sierra after several quotes from other companies. Sierra wasn't the lowest price but they presented their work process with professionalism and knowledge.
This was to be our forever home and we didn't want any problems in the future. All the staff I have met and worked with were terrific to say the least.
I have had a maintenance contract since the huge installation. They come out Spring and Autumn to take care of any minor problems and ready them for the season. I
n addition, we had a Pure filtration system that uses a UV light as well as filters that get replaced every three years. No need for intake filters being changed all the time. The Pure takes care of bacteria and virus, which we were thankful for during the pandemic. We did not get Covid!
All additional work this last maintenance for Winter was performed by Tunde and Nikus, two great professional and patient service reps that make the work here thorough and quick.
I highly recommend Sierra for all your home maintenance whether you are looking to replace your A/C or you need service. Thanks for the trust and loyalty and how you treated me.

Beware and be warn of scam from this company. Make an appointment to have a service on a 8 years old a/c unit not turning on. Sierra A/C & Plumbing sent a tech to diagnose on the unit and states it can't be repair cause it too old. Suggest we need a new entire system condenser and furnace to be replace. He quoted me $20,000 3 tons 14 seers Lennox brand. I felt very uneasy about this service. Its a 8 years old unit, most a/c unit last up to 15 to 20 years. I called another company to have a look at our condenser. They found out the a/c contactor not engage when the thermostat turn on. The price for the part and labor is reasonable. He also added a couple pounds of refrigerant. All total under $350.
I would not ever ever use Sierra Air Conditioning & Plumbing. Not a trusted HVAC company.

After visits from two other HVAC repair companies (for a total of 4 visits) through our home warranty company, we finally decided to call Sierra when the problem persisted. They were super fast to call me back, and were able to get a technician out to our house about 5 hours later - even on one of the hottest and busiest weekends. Tyler C. came over to check out the problem and had it completely solved within an hour. I could have cried tears of joy. Tyler was INCREDIBLE - so knowledgeable, professional, and overwhelmingly kind. He went above and beyond to make sure the problem was fixed and even gave us advice on how to better regulate our zone heating/cooling unit. I have never, truly, been more impressed with a service provider than I was with Tyler. Would definitely recommend Sierra for any HVAC/plumbing issues. Just make sure you ask for Tyler!

This company has friendly service that seems to be skilled at their work. The Membership Rewards program is a nice feature, except that the promise of 'Priority Scheduling' (see web site: sierraair.com/membership) which is listed several places on their web site - is patently false.
I confirmed this on our last appointment scheduling attempt with the receptionist. The receptionist verbally confirmed there is no priority given to members - they schedule whoever calls in first-come, first-served basis, with NO PRIORITY WHATSOEVER given to club members.

The web site should be updated to reflect the fact that the priority service is not actually a benefit of membership - some people may base their decision to become members on this falsehood.

The other information on the web site does appear to be accurate, however.

We pay for their monthly service membership and a few months ago had them come out for an inspection. Now screws are missing from the outside AC unit. I called and the woman I spoke to was rude and condescending. She said I highly doubt he looked at the outside unit. I then told her we have a video of him out there on our Ring camera, but we shouldn't need to prove this with her implying we were lying. She then said yes, they look at the outside units but she still highly doubts they lost the screws. I am not paying for a $60 fee for them to replace the screw I'm pretty sure they lost. I have never touched the AC unit myself. This situation wouldn't have so frustrating is she had a better attitude on the phone too. We will be canceling our service with them.

Sierra Air Conditioning replaced our system about 3 weeks ago and I couldn't be happier with it! My husband and I went with the 2 stage option and I can't believe how quiet it is compared to the old system! We also added the upgraded filters and lights for our allergies and it has made a world of a difference! Our installers, Jon T and Mario R, were very pleasant and courteous while in the home. They covered the floors and cleaned up after themselves. They made the whole experience easy!

You get 2 stars only because your technicians are satisfactory. Your scheduling is complete and utter garbage. This is the second time we have waited 4 hours for a maintenance tech to come out only to be told that he was a service guy and couldn't do maintenance work. The first time no one even showed up. Both times I've lost out on work because having to stay home. Get your sh*t straight.

03/05/2021 12:00:00 SA

This is for their plumbing service. Ruben came out ahead of schedule and was from the beginning friendly and respectful. I always appreciate a contractor that brings in booties for their work boots.

I'm not the most handy guy especially when it comes to plumbing but Ruben explained the different types of blocks and what type of service they would be able to perform.

Small back story Sierra plumbing was actually the third company I called to fix this slow draining tub. Two were thru my warranty company, first guy got his snake stuck in the tub and had to call someone to get help. Second company plumber came out literally only looked at the tub and said because of the age the entire P trap would need to replaced and would be about $7k!!!! Because of access to trap. I was amazed the pipe whisperer was able to tell that by merely looking at my tub. No diagnostic or even filling of the tub.

So back to Ruben, actually tried to diagnose the problem as novel as that seems!! Filled up the tub with wAter saw what was happening. He grabbed 2 plungers, rags, and tape from his van. He came back and started working his plumbing magic. At first no progress, but he literally said , I don't like to quit that easy and tried something else. Like a magic show the drain starts to open up. He recommends letting hot water continue to run down. He give me a couple tips seeing I have older cast iron pipes (house circa 1970). We then double check the problem js fixed by letting the tub water continue run. Then let the shower run for about 3 min each. No back up!!!

20 min and literally thousands of dollars cheaper than warranty company plumbers, my tub drains and works. Thanks Sierra Plumbing. Calling you first for plumbing issues in future. Cant speak to their AC but plumbing is 5star for sure.

Wow! incompetent representatives, horrible customer service. Had service call and guy collected no information, he had to come out to do same visit over again. When speaking with a supervisor, from the start she had a bad tone and attitude on top of that she did not express that it mattered at all how they dropped the ball and did not care to take any steps or make any suggestions on how to make things right. I would not recommend this company.

About10 years ago we had our ENTIRE HVAC units replaced by Sierra Air. This included AC compressor unit and furnace. Price was a bit high but it was LENNOX brand which is about The best in the industry.
No problems over the years. Sierra Air sent techs to inspect yearly when I made the appointments.

This year the tech said I had a problem with my start capacitor so I bought a hard start kit for $598. discounted PRICE with a $195. yearly service membership.
THEN out of curiosity I looked online at the prices of hard start kits for my 3 ton AC compressor. AVERAGE price was about $45. !! Highest price was $64.
After talking with a Sierra Air representative the most they were willing to give me was a 10% discount. This price gouging is absolutely WRONG.

I FEEL MY WIFE AND I HAVE BEEN HORRIBLY RIPPED OFF BY SIERRA AIR AND ARE DONE DOING BUSINESS WITH THEM!

I had Melvin come out to service my hot water heater. He did an outstanding job. He answered all my questions and he informed me on how I can keep my hot water heater in good order. The only miscommunication came with me and the young lady that I spoke to on the phone when I called to schedule an appointment. She told me that a new anode rod would cost $89.00. Melvin told me that the price was $138.00. The unit needed a new anode rod so I had him replace it at the $138.00 price tag. Melvin was excellent but the people taking calls need to be accurate when customers ask about pricing. There is a big difference between $89.00 and $138.00.

On 20 May 2020, Sierra LLC came out for routine maintenance. I was informed that there were specs too low and was recommended multiple parts to be replaced which would cost anywhere from four hundred to the six hundred dollars. I declined and had another company come out a week later and nothing was wrong with my unit or parts. The only thing needed was for my unit panels to be taken off and sprayed. I was with this company for years and every time it was recommended I replace a part. Luckily I declined every time. This company just attempts to take money when NOT needed. I will not ever use this company again nor do I recommend them.

This company installed the HVAC system in my home 11 years ago. I've been using them on and off since then for maintenance , as needed. Overall the system has been pretty reliable (Lennox).

Last summer I did a regular maintenance service call. The technician suggested I upgrade my system with what's essentially a surge protector + new capacitor. This would prevent any issues in the event of micro or macro power surges.

The suggestion wasn't aggressive or what I would consider an upsell. The reasoning for the suggestion made sense to me. My area tends to get these types of power surge events so I agreed to do the upgrade (it also came with a new capacitor which was a plus as these tend to go out every few years). The total cost was $700 with install.

The technician came back for the install. But after the install , there was a problem and the ac wasn't blowing cold air. After some troubleshooting the technician discovered the part was faulty and caused a short circuit which triggered a circuit board to fry.

Needless to say , Sierra came back and replaced the board but also discovered that a zone deflector was damaged. They then came back and replaced the zone diverter/ duct.

All in all - the faulty parts caused a lot of damage. What impressed me was that Sierra took full accountability for the faulty part and fixed everything that was damaged because of the faulty part. Even the zone diverter which runs on a separate circuit - technically they could have argued it was an unrelated issue but they took care of it.

I've been burned before by shady companies who don't take responsibility for things. It was refreshing that Sierra took accountability and fixed the issue without any additional charge.

I know enough about manufacturing, mechanics and electronics to realize that faulty parts can happen. The fact they took care of everything stood well with me. The technicians were professional and courteous. They wear booties inside the home.

I see a-lot of reviews mentioning the additional charge for parts compared to Amazon. But you're paying for the peace of mind that the part will be installed correctly and if something happens there will be accountability. I've had enough bad DIY experiences to know that sometimes you need to leave things to the pros - but not every company is professional.

The mark of a good company is how they take care of customers when things good bad or unexpected. Through this experience Sierra demonstrated to me that they are an ethical and trust worthy company. Something that you don't see too much in the local a/c industry due to the dependence we have to them living in a desert.

So much for Sierra's SAM program. We have paid $16/mo for a service contract for nearly 2 years. We have a situation with a possible bad bearing in the fan motor. Sierra was scheduled to come in November for semi-annual maintenance & service. A request to come early to evaluate was met with a charge of $59. I informed the receptionist that I would cancel future service if there was a charge. Could not be sure, but it sort of sounded like, tough break. Maybe it was my imagination

This is an apology. Joe Ates of Sierra Aire came out to do our semi-annual preventive maintenance. He was most personable, efficient, and knowledgeable. He recommended a change in the type of A/C filters, as our current ones, changed on October 1, were dirty enough in two weeks to cause whistling at the intake when the fan was on. Tis is by far the best service we have received, and we will continue our contract, thanks to Joe Ates.

From the first time I have ever turned to Sierra LLC to now, the service and quality of knowledge and products have impressed me and won my trust. Today, another wonderful technician, Mathew Parayno, came to assist. It was supposed to be a system check for the summer, but he found a solution to a problem sure to bring out electric bill down significantly. His knowledge about his work also lead to us figuring out what was causing the whistling from the filters by showing us a better quality product. I would recommend Sierra to everyone, and I hope all of you get assisted by Mathew Parayno! Ask for the best!

Sierra LLC Air Conditioning & Heating has been my go to HVAC repair/replacement contractor for 21 years. Sales and Service technicians are professional, careful and they follow cleanliness and CoVid guidelines. The Lennox system they installed two years ago was pricey but high quality and is working well. Folks I've referred to Sierra have generally been happy with them too. Not only have I been with them for a long time but their team members stay with them too and this speaks volumes to me about the company and the people who own/operate it. It's hard to find high quality contractors in Southern Nevada. Thanks Sierra for being one of the good guys.

Horrible company. They try scare tactics to get you to buy a whole new system when there is nothing wrong with my current one. They also try and pressure sell you extra stuff that you don't need like surge protector and $120 air filters. Do not use Sierra.

I bought Groupon for an AC tune up provided by this company. The tech, Fernando, arrived promptly and checked my 30 yr old system. I asked him if he could give me quote for a total system replacement. He could not since that work was provided by another tech with the company. He then called the company and they sent the tech (Shawn) to look at my system and provide me with a quote. I feel Fernando and Shawn went above and beyond what was required. I appreciate their expertise, honesty and knowledge.

Big Thanks to Tracy D. for showing up to fix our AC on this extremely hot summer day. He got to work quick and our AC was blowing cold air again within 10 minutes of his arrival!

When the repairs were done, he came into the house with his mask and gloves on which I really appreciated. Tracy was friendly and took the time to answer all our questions.

We had overall great experience today with Tracy and Sierra Air.

Our tankless water heater had a leak. Sierra sent Melvin that evening even though it was after hours. He was quick to figure out the problem. I received the replacement part within a few days. Melvin came back and was able to complete the repair quickly. He was very professional and great at explaining the cause of the issue. Thank you for your help!

Extremely pleased by the quick response to a leaking unit in the attic..
Drew came out and found the problem right away. When unit was installed it didn't have proper pitch to drain he quickly fixed the isssue and now it's draining correctly!
Thank you Sierra Air for coming out within the hour and Drew for quickly fixing the problem..

If i could give this horrific company 0 stars i would, My house was built in 2015 and they installed my AC unit. The AC unit is under warranty for parts and had a 1 year warranty for labor. This company wanted to charge me $89 dollars to come out and diagnosis the problem, After my complaints, they offered to lower the service call to $59, their preferred rate..BS. I called multiple companies and most don't charge to come out or a very reasonable fee, this company here is pathetic in their business practice and I would not recommend them under any circumstances!!!

I have worked with Sierra Air for years and would not use any other company for servicing our home HVAC systems. We recently had a repair completed and signed up for the SAM Maintenance Plan. We had our included heating system tune up scheduled and Justin C was our tech. He was on time, knowledgeable and friendly. He thoroughly explained what service was being completed, with pictures to document the service. We will be requesting Justin C as our tech when it's time for our cooling system tune up or any required maintenance!

I have never worked with Ulysses before in Las Vegas, Nevada and with his thorough and go to work right away approach it was refreshing and definitely professional-- he can come back again. I don't give 10/10 very often but when I do as my friends would say that is saying something right there. He definitely gets a 10/10 and made very little clean-up and left no damage. He also went over the notes from the last tech by actually pulling out his phone to read what if anything was said and while nothing was noted as the last tech assured me it was I was able to get the notes from the last visit and Ulysses went through what he wrote and got me the actual price I'd pay as a SAM member not what the last tech wrote as a non-SAM member. It pays to be a SAM member as there's always a discount on parts and that's key nowadays. Ulysses is a good asset to Sierra Air as a company and that they should keep him for as long as he wants to stay.

Had Sierra Air come out for maintenance on my A/C since it was installed by the builder. They came out on June 11,2020 and gave me a list of problems, I called back to ask a couple of questions to the Technician that came out and to set up an appointment for repairs, they said he would call me back, never received a call, so I called back a second time, again no response, so I went with another company.
I had signed up for their year service, which included a Summer and Winter maintenance which would cost me $16 a month for 12 months which would be $192 for the year. When I called today, July 17th to cancel their year maintenance, they tried to charge me $193 more today, plus they already took out $16 for June and $16 for July so that would be a total of $225!!! She said that I would be paying their regular price if I cancelled their maintenance service now!! Be very careful when using them.
Update**** Received a call from Zach, he was able to rectify the problem above, he will be following up with the office staff to see where the ball was dropped.

Sierra LLC Air Condition & Heating just completed a repair and maintenance visit at my home. My furnace drain line became plugged from dirt and grime dropping down by flue into the furnace. I contacted Sierra late Thursday afternoon and they were able to schedule a repair visit for first thing the next morning.

Darrel O arrived within 20 minutes of the morning call that he was in route. The appointment was for 8-12 on Friday morning and the appointment started just after 8:30. Upon arrival, Darrel introduced and identified himself. He provided me with background on himself, identifying his total experience and employment with Sierra. Darrel's manner was professional and he completely reviewed the work that he would perform and outlined how my heating and cooling system worked, before embarking upon the repair. His purpose was to ensure that when he reported on the situation in my furnace and drain line, we would be starting from a common position. Having little furnace and heating experience. It was a great way to start.

My emergency problem was a plugged line which arose from materials falling through the ventilation pipes of the furnace. Darrel cleaned and tested all vents, pipes and drains that were necessary to eliminate the current problem and prevent any near term future issues. He checked the furnace pipes and connections. My second issue was that my supplemental air circulation controller's display had ceased to function. Darrel made a recommendation to replace the equipment and installed the new equipment in a timely manner.

After completing that work, Darrel presented alternatives for us to consider regarding future preventative maintenance visits and services that were available. If we elected to sign up for the annual maintenance program, Darrel would perform the seasonal maintenance on our air condition unit and exterior heat pump. We like the price and especially the convenience of having the work completed at this time, avoiding scheduling a second near term visit. The inspection and preventative adjustments and other work was completed in a very prompt and professional manner.

The heating and cooling system was fully tested while Darrel was here and the system operated just fine. Darrel completed his work in a very thorough and timely manner.

We are extremely satisfied with the timely repair, installation and preventative maintenance work which Darrel and the Sierra team provided to us. We felt we received great service for a very reasonable price.

Let me say if i could give less than one star i would so monday night my ac starts shutting on and off was told the compressor is going i called my warranty company who gave me a company who had a six day wait period which i can understand its las vegas it's hot however about ten o'clock i call sierra who says they will come out if its an emergency which i have a child and animals and i myself get sick from prolonged heat so i say yes please come out they say someone will be there within the hour so 11 ish a tech does show up i tell him the compressor is going off and on and it's blowing the fuse and there was no power to the thermostat cause it's blowing the fuse, he then says well thats why the ac isnt working cause there isnt any power to the thermostat as if he heard nothing i said but im dont work in the ac business so what do i know he walks over trys to take the faceplate off the wall and starts pulling and juggling at it and throws his hands up and says he doesn't know why it won't come off...the finally takes the screw out that holding it on and it falls apart so clearly now i need a thermostat at 139 dollars , which is fine nothing i can do now so he replaces it surprise still doesn't work like i told him, he then goes up on the roof and comes back down and says the fuse is blown ....still i had already told him that so he switches it out and it comes on he goes outside to wait to see what happens and of course it shuts off again he says well i guess it wasn't the thermostat then tells me its 139 to go back onto the roof to see what else it could be while in the house he keeps telling me man it's hot in here he can't keep the sweat off as if i didn't know that that is why i called you out so he goes back up on the roof tells me its the fan that's going out and for 600 bucks he can replace it at this point if its just a part then im ok with him fixing it i eve said so its not the compresser he said no just the fan i said are you sure he said yes mam so i say ok we'll do what you have to if it's going to get it back working....he comes back in to ask me if i have a screw driver he broke his never thought anything about gave him the drill with screw bit he's up there awhile comes back says it's wired wrong it's late he's tired he'll come back in the morning he takes my drill with him he then shows up in the morning and i ask if he still have my drill he says yes mam i don't need i have a screw driver so up on the roof he goes then comes down tells me its the fan and the compressor and that id need to replace the whole unit after i had said i didn't want to bandaid anything for a large amount if i was just going to have to buy a new one and then magically i need to replace it he then calls a salesman who comes out tells me 8770 for a new unit i tell him i'd have to think about it the tech then calls his boss and he starts ranting and raving he was here all night and now he needs to take the parts back off cause i'm not buying their unit and how is he gunna get paid because he was here all hours ...as if blaming me because he couldn't fix it and i wouldn't buy a new one from them, they i call to have the warranty company come look at it to find out he didn't even put back on the items he took off just left the wires hanging out and the broken fan laying on the roof with a broken screw tip hmmm wonder how that happened?? So now i'm forced to buy a new ac because they couldn't even put it back the way they found it because he apparently didn't get paid enough for not fixing my ac ....i then call to speak to manager or someone i get told no one is there who i can speak to but i can leave my number or a voicemail which i was angry said i would take it up with bbb and hung up then i did call back because i wanted to see if someone would actually call me back three hours later someone calls me back that calls from a blocked number and doesn't leave her name says she call back tomorrow so now all these things that happened and your boss calls from a blocked number hmmmm now everything seems planned out to get me to buy a 8000 dollar ac unit as a manager or supervisor who works in customer service and you can't leave your name or a number to call you back seems like they don't care about their customers however i'm guessing one angry customer to the 99 others who are doesn't really matter...i won't go back there and good luck to anyone that does.

Always professional & prompt Sierra should be applauded on their hiring process/employees.

I've had several technicians in my home and never felt uncomfortable or uneasy with any service evaluation I've received.

My last technician was Andres.

Overall, I was most impressed by his professionalism and friendly demeanor.
He was very detailed with explanation of fees and photos of each repaired item including before and after pressure readings.
I will be requesting Andres for my next seasonal checkup.
Thank you Andres & Sierra Air.

Do not trust Sierra Air Condition they came out and said I needed the following parts replaced Control Board/Blower/Start Device. Charged me $2,600 for parts the system worked for three days actual cost of the parts $661. Called them back they said $7,700 to find out were the leak was coming from.

It's funny that all the good reviews have one review and no pictures or friends. That's shady right there!! Just like this company!
My mom called this business to have her heating checked. The technician was 3 hours late and spent some time in the attic diagnosing the problem. He came down and quoted her 8000 dollars. Then he called his friend to come out- who showed up with a binder and told her she should buy an all new heater and air conditioning system. Even though the entire air system was replaced 4 years ago. He tried to sell her on the 10,000- 11,000- and 12,000 units. When she said no, he pressured her like a car salesman!
So we had another HVAC tech come and check it out- a friend of the family. He fixed the heat for the cost of a $40 part!!! 12,000 to $40???
Is this place a joke??
They tried to take advantage of my mother...which is even worse in my eyes.
The supervisor called to try to to smooth things over and say that their assessment was right and if the unit is fixed then they would like to come back out and verify it and handle the problem with their crooked techs in house. But these people are never coming near my mom again!
Get second opinions people!!!

We've done business with Sierra on a couple occasions now, and with each visit the quality and service has been excellent. The house we moved into had a bad hot water heater and typically hard Las Vegas water, Ruben came out and was able to get us taken care of on a new water heater and a whole house softener system that was ideal for our needs. The installation was professional, they resolved some issues left by the previous owners, and we're still very happy several months later.

Recently we had an issue with our air conditioner (existing unit from previous owner). Sierra was able to get a tech out quickly. Derrick was courteous and professional, quickly identified the problem and performed an inspection of the unit so we could identify any other impending issues (because nobody wants to pay to get the air conditioner fixed, only to have some other part of the unit fail next week, right?). He took pictures and videos to show us the problem, as well as a potential future problem. He was able to get the air conditioner back in action on the same day, and with a little extra work took care of something that could have turned into a big problem in a few months. We are very happy with this company.

Scheduled for a simple maintenance for my heating system because I'm in the program. The technician left the jumper cable in the mother board and I'm unable to turn off the unit all night . My house was on 98 degrees , had to sleep with my windows open. I've been using portable heater inside my house to save money but then again I'm not sure how much my gas bill this time because it was running for 24 hrs cuz I couldn't turn it off. Such an inconvenience and a waste of time and money . Would not recommend this company.

Came home with water all over my garage, leading to the water heater. It's 8 years old and I'll admit was not maintained well. Made a call and a few hours later Ruben shows up, he had a plan to replace it same day. He's very professional and delivered on his promise. He worked late to make it happen but it's nice to have hot water in the AM. I highly recommend Ruben, he gave tips to extend the life of the new water heater. This company is first class in customer service. Not easy to find that today.

We had an AC scare, plus the unit was 20+ years old so we started getting quotes. During the decision process, the AC went out on a Saturday night on the hottest day of the year. Called our sales rep, Shawn, & asked him to plz call back. We had made the decision to go w/him but we were going to call on Monday to move the purchase forward. We weren't even an official customer yet but he called back w/in minutes. He said they were hugely overbooked but he offered to come by at 8AM the next day, a Sunday, to diagnose the problem & text a tech to come w/the correct part to get the AC up & running again. Can't say enough good things about Shawn, the tech that fixed our unit & Raul & Omar the guys that installed our new AC. All were exceptionally nice & competent! But then we had to deal w/the office/billing side of the company. OMFG, it could not have been worse! We had an agreement in writing that we would charge 10K on a credit card & write a check for the remaining balance. Before the install they tried to run the full amount on the CC, it was denied as it was over our limit. I was not happy as this is a ding on our credit report. Shortly after the install they did the same thing again even though they had already cashed our check. They dinged our credit report again & we're in the process of applying for a loan for solar panels, not happy! 6 days after the install they did it again! This is 3 screw ups all affecting our credit rating! I can't say enough bad things about their office staff & management that allows this kind of incompetence. Great sales & install, horrible office support. I do not recommend this company unless you're paying cash or don't mind your credit report negatively affected.

Update: 8/25/2021, there was a problem w/the initial install that I was told about, housing from unit to house wasn't fabricated correctly. Not a problem, they were up front about it, had a temporary work around & a permanent fix to be installed shortly. Raul & Omar came back today to put in the fix & again, I just can't say enough great things about these guys. They are the gold standard representing a company. They communicated everything they were doing in a clear & concise method, being respectful of my time & highly conscientious about doing the job to their hi standards. Polite, respectful & hard workers. Clone these guys then all installs will go as well as ours did! Upped them to 3 stars from 2.

Because of the power outage last night , one of our A/C's broke down. Called this morning and fortunately after 12pm appointment is available. Tracy is so knowledgeable with job and explained to us what went on with the problem.

Also recommended and explained the program , i signed up with SAM and instantly with the diagnostic fee, i saved $30. Tracy is professional and was able to answer all our questions. This will be the start with our professional dealings with Sierra as we just moved here last March 2020 from San Diego.

More Power to Sierra Company.

Our AC went out in our home and AHS home warranty could not get anyone out for a week. After two nights of 90+ in our house, I called Sierra Air Conditioning & Heating on Friday. They had a service tech out to our house that evening. The Service Tech Jared was professional, knowledgeable, and helpful. He wore booties as to not get our flooring dirty and put down a pad to protect our floor when he setup his ladder. Jared explained the problem and answered all our questions. He was able to fix our AC unit in less than hour. As our HVAC unit is over 15 yrs old, we will be replacing it and using Sierra Air Conditioning & Heating! Highly recommend using Sierra Air.

Can't say enough great things about Sierra Air Conditioning! We had to replace our A/C unit this week. Not only were they very competitive with their pricing, but the two technicians that came out to install the unit were very polite and professional. They were very thorough in their work, answered all our questions with our new unit / thermostat and made sure everything was working properly before they left. They cleaned up after themselves and left our house spotless. They kept us informed every step of the way. I would highly recommend Sierra Air Conditioning to anyone!

DO NOT USE THIS COMPANY FOR REPAIRS TO YOUR AC UNIT! Unfortunately, the builder of our home used Sierra to install our AC. After being in our home 1 year, we noticed that the AC unit downstairs didn't feel as cool as it should when we changed the temperature on the thermostat. We told our builder and they had Sierra come out and supposedly fix it. We don't run our AC below 75, so we didn't really notice a difference. Recently, we had it checked again and it was the same issue. The charged us $800 in labor fees to fix the same issue - this time saying it was a different repair that needed to take place. The unit is literally 4 years old and we don't run it very low. I asked Adam the manager of COD department to refund us the labor fees or do something meet us halfway as its the same exact issue we dealt with before. It took him a week to get back to me and they weren't willing to do a single thing. I asked if the 1st technician could have made a mistake and repaired the wrong thing.. he said YES, but still wasn't willing to do anything about it. I will NEVER use this AC company again.

07/11/2019 12:00:00 SA

My AC unit is less than a year and a half old and we had to call out a tech. We called this company because of the warranty. I was told the warranty would not cover the labor and that it would be an $89 fee for them to come out. This is standard and not where the problem lies...I was also told over the phone that $89 is all I would need to pay and everything else would be covered under warranty. Then after the technician arrived and spent less than 5 minutes diagnosing the problem, I was told that it was a bad capacitor. This is a $30-$60 part and then I was told there would be an extra labor charge of $171 to fix it on top of the $89. This made the total $260 to fix a warranty part. I had to call and complain just to get the original $89 as part of the labor fee. So I paid $171 for a part that he spent less than 5 minutes to fix. I could've called another company even after paying the $89 and still saved money. Even with the parts under warranty, I will never use this company ever again because their cost for labor is insane. How do they stay in business? It won't be because of me...that's for sure!

Sierra also will refuse to give you a breakdown on what your paying for the AC unit, furnace, labor. The reason they do this is to high gross you and if you have to take them to Court they will only have to pay standard rate and charges back. Basically they double the price of the unit and the labor. Full retail on the Goodman AC and furnace package 13 seer is 2,800 so a 9,000 quote is downright theft for a 4 hour job. I'm more then happy with the work and the price I got with Air Supply 2 year labor warranty and a name brand Amana unit I also had the choice of a York for a little less or a Trane unit for same price.

Our service tech, John Skura, from Sierra came out today for our first service with this company and the experience was wonderful. John was professional, friendly, honest and straightforward. He did a fantastic job on the maintenance of our A/C unit. I also signed up for the Sam's Service Agreement they offer since the value is worth the modest monthly charge. I can see why Costco chose Sierra as their go-to HVAC company. This was a great experience overall and highly recommended!

Called late last night about my ac unit not cooling the house down. It wouldn't go below 82. I called the company that installed it 7 years ago and they recommend replacing it. I called sierra ac and they came out the same day....replaced some part....cant remember what he called it and it is working fine now. I am happy with the quick and honest service. I Will use these guys again and tell my friends about them too.

I am so happy I found Sierra's booth at the GreenFest event and I'm even happier that I was assigned Richard A. for my service call. Richard was AWESOME. He ensured that my system tune up was complete and that I understood what was going well and what items needed attention. I will be requesting him for all my future service calls. Sierra LLC just earned a lifelong customer today.

STAY AWAY. They came out last night, charged us $350 for a $25 thermostat that still doesn't work, and then wanted several hundred dollars for 12 pounds of freon and told us it could cost $3000 to fix the leak. AFter telling them to leave we called another service company who found the valves were loose and put in 2 pounds of freon and we have heat. Sierra will size you up and try to get as much as you can when you are vulnerable with no heat or cooling. STAY AWAY.

ZERO stars. Incredibly upset with this company. We bought a new home and moved in last August. In November we started to turn on the heat and noticed a gas smell. We reached out to the customer service rep for our builder and he said the smell was most likely a metallic burnoff that most new homes have and we believed him. We ended up calling Sierra Air directly in January because we were still smelling gas. A tech came and said that he found a very small leak and that he fixed it. Two weeks ago I turned the heat on again and left the house for a few hours. When we got home the entire house smelled of gas. I immediately turned off the heat and ended up calling Southwest Gas. they sent a technician out immediately and he found a HUGE leak in our attic. the cap to a gas valve was missing completely. he said thank goodness we called because we could have had an explosion at any time. I then proceeded to call our builder's customer service rep and he said that leak should have been found before we even recieved the keys to our new home. So my entire family has been breathing in gas for months due to Sierra Air's gross negligence. Steer clear from this company! Your life literally depends on it.

I had a terrible experience when my AC stopped working, but fortunately, Harry A. arrived promptly, assessed the problem, and fixed it within an hour.

We just received our service from Michael Johnson from Sierra. Very professional. Explained everything we needed to know about our AC and UV filter system and suggested upcoming maintenance that we should consider on next visit with all of the options. This was recapped in writing and emailed to us for our files.
Sierra is a great business to work with and we feel they take amazing care of their customers.

Jonathan and Pedro came out and fixed my AC unit. They were on time and were able to pin point the problem quickly and economically. Jacob from the warehouse team was also great to work with and was able to consult the technicians onsite and was able to fix the issue. This is a great and honest company. I would highly recommend them.

POOR CUSTOMER SERVICE, UNRELIABLE, AND DOES NOT OWN UP TO THEIR MISTAKES: Sierra Air installed our AC in 2012 and has performed the maintenance for it until 2017. At that point, we were no longer happy with the quality of their customer service and switched to a competitor. When the compressor of one of our two units failed in 2018, the other company discovered that Sierra Air had failed to install a metering device that resulted in the early failure of the compressor. We talked to Debari at Sierra Air on 6/14/18 who, by phone and without examining the system, denied the possibility of them failing to install the metering device. They implied that the other company took it out to make our system fail. Debari said he will consult with his leadership, call back, and send a technician on Sunday 6/17/18. We made arrangement to be available on Sunday. He didn't call back. I called twice on 6/15/18 and was told that he was at lunch then unavailable. Finally, McKenzie told us and that no technician was available on Sunday. She said she would send someone on Saturday between 2 and 6 pm. I explained to her that we had plan and needed to leave the house at 4 pm and that they would need to be done by then. She said that she will try to make them come early. She also said that her supervisor would call us in the morning of Saturday 6/16/18. It is now 2:39: no phone call, no technician, and more importantly no recognition of their failure to install a device that resulted in the early failure of the compressor, a more than $3,000 cost of repair.

I couldn't have been more pleased with the service and the speed of Sierra. We called them at around noon on a weekday, hoping that someone could come out quickly to help us with a clogged toilet. We had tried our plungers and snake and seemed to only make things worse by also breaking the sewer seal. We had water coming up from under the toilet and dripping down into our garage. I was initially a little annoyed, as the dispatcher wouldn't give me a timeline for service. I had work, so it would be nice to get an idea of when someone would be able to come out. But we put our name down anyway and waited.

Thankfully someone texted us about an hour and a half after we reached out, notifying us that they would be at our house in 45 minutes. Richie was here right when he said he would be. He was really knowledgable and friendly, and got to work right away. Unfortunately the clog was further along than even his 30 foot snake, so he had to call in a drain specialist, Logan. They brought in a 75ft snake that finally did the trick. When they were done they cleaned up the area thoroughly and re-caulked the toilet.

It wasn't cheap. The whole thing was about $900. But considering we don't have a 75 foot snake laying around we really couldn't have done this specific task ourselves, even if we had wanted to. If we ever need anything HVAC/plumbing related in the future (which seems likely), Sierra will be the first folks that we call.

There wasn't any cold air blowing in my downstairs AC system so I gave Sierra Air Conditioning a call and the tech they sent out to have a look at it was Andres Valdez. He initially informed us that there was a leak coming from somewhere but he didn't know exactly where. He recommended they do a leak test the following day and luckily they were able to detect where the leak was coming from. Andres was very professional, knowledgeable and helpful explaining all the problems they found and showed us pictures and videos of all the work they did which I truly appreciated. So glad he was able to fix our AC system in time for my little girls party! Would totally recommend Sierra and Andres for any AC issues you have and we definitely will be using them again and asking for Andres to do our yearly maintenance checks!

Today I had my rooftop unit replaced. My installers Jayce and Jayrell were amazing. Work with the crane operators was very smooth considering the wind. They were polite and professional, they knew exactly what they were doing and had all materials needed to do it right the first time. They wore booties in my house and even greeted my dogs. I'm very excited to know I have a well installed, reliable system for the summer.
Highly recommended

We have had them out numerous times. Our property management sent out a sketch company. After 2 weeks in vegas with a $300 power bill we called Sierra. They showed up on time. Very friendly. And a great price. Now if I could only find a new property manager.

Today we had our scheduled maintenance for the first time through Sierra. Josue arrived on time and was very professional. He walked us through every step of the way, explained everything to us and answered any questions I had. We had a wonderful experience and I can't recommend Josue and Sierra enough.

Sierra is an excellent Air Conditioning & Heating company, very dependable, honest & efficient company, the office staff & service technicians are very nice & very helpful. We had our Fall/Winter Furnace Maintenance done today, we received excellent service from Eric Otero, our Service Technician. He is very nice, pleasant, efficient & explains things very well.
We're also glad that they have a Sierra Maintenance Program (SAM), it reminds us to get our AC & Furnace serviced regularly. It is affordable & reasonable.
I would highly recommend them.

Absolutely hands down the best customer service my wife and I have ever received! Robert was absolutely INCREDIBLE!!!!!!! He explained every step of the way and fixed our air conditioning unit on a 108 degree night at MIDNIGHT while my pregnant wife and I sweated. Robert is a TRUE PROFESSIONAL!!! And if your able to request him you absolutely should!!! I seriously cannot say enough good things about him! From the minute he walked in with booties on his shoes, to the professional and sheer perfect service and assistance. He even went above and beyond to correct every single tiny and minute detail pertaining to our AC unit. His knowledge of HVAC is unmatched and we will never use any company other then Sierra because of this experience. I'm amazed that Robert is not the area manager or super intendant because of what an amazing and thorough job he did. He turned our desert of a house into a cool and comfortable home. We can't thank you enough for everything you did Robert!!!!

Our ac gave out and Sierra sent out three technicians who immediately set up our new system quickly and efficiently. They were very professional and answered all my questions. I want to thank John , Miguel,and Daniel for such an amazing job they were very genuine and helped us get the perfect new system for our home. The system was also quite big which meant they had to remove some drywall from the attic to get it in. They promptly brought in a drywall team to leave it like it never happened. I would recommend Sierra for anyone looking get a new air conditioning system or like me finding yourself unexpectedly needing a new unit they saved the day.

I have used this company for many years for my A/C and heating. They are timely reliable and effective efficient . They always notify me if the technician is on the way, including sending a photo so you know who is coming. I recently had the spring maintenance on my A/C unit that they had installed 4 years ago. The technician, Robert Young, was pleasant, polite and friendly. He put on and took off his shoe covers each trip in and out of my house. He carefully explained the maintenance he had performed, and any suggestions for better performance. I recommend this service.

Absolutely terrible customer service.

We purchased the service plan that gave us priority service and two inspections per year.

Made our service appointment three weeks ago for Monday the 17th and i was told it would be between 4-6pm. I marked it in my calendar as that as well while
Talking to the girl on the phone.

Monday comes and at 6pm no tech has come or called. I called Sierra and was told it was an appointment for any time after 4pm until whenever midnight who knows.

I told her no I was told it was for between 4-6p to work around our schedules.

Even though we had the service plan they would
Do nothing. I have asked for a full refund of the service plan and I am disgusted. Sierra installed our unit and I paid for a service plan and I can't even get a simple service call to check on the unit.

I don't know if I will ever use these people again. This is a scam to purchase a service plan have to wait three weeks for the appointment and then no one shows and I'm told something totally different from what I booked.

I would hope someone would the decency to follow up from Sierr

Updated review

After the previous review was posted Susan called me
The customer service manager and set up a new appointment and apologized for all of the issues. I decided to go ahead with the second chance and everything went perfectly.

I am glad that even though they had some issues with customer service the company was quick to fix them and did and also had excellent follow up.

Will be using Sierra again and i was very happy with the way management handled this situation.

Thank you Susan

We just had our heater inspection with Tracy Denson and I must say he was knowledgeable, efficient, and courteous! He did the inspection and told us what was wrong and what he fixed under their inspection program and I'm so glad I signed up for it! I will also be contacting Sierra to make sure we only deal with Tracy from now on. I appreciate his customer service and details on his inspection. He was very clean and put down the cover on the carpet and did not bang the ladder off anything in the house so 5 stars to you Tracy for spectacular service!

John S and Jordan showed up to the house for a seasonal inspection. They were polite, respectful, and went through their inspection step by step with me. John S is passionate about his work and it shows.

Very satisfied with the quality of the inspection and working through the remedies with me. Is it the cheapest option, probably not. For me, that was OK considering my situation.

I had Ruben, head of pluming division come to my home today to check out my water heater. Ruben started off by explaining what he'll be doing and checking for with in my water heater. Ruben did a great job on costumer service, making sure if I had any question along the way. Once Ruben had mostly emptied my water heater he explained what he was looking for and what his pros and cons were about my ten year old tank. Ruben had more pros for me to hear and that just made his visit even better. So at this time Ruben did not have to repair anything on my water heater. Like I said before, Ruben always asked if I had any questions or concerns. I did have a few for him and Ruben gave me some great info to my questions. Ruben knows his stuff. So if you ever need a plumber I would highly go with Sierra LLC and ask for Ruben.

I used the yelp project help to find a company to handle replacing our HVAC unit. Due to the placement of the unit I was turned down by 2 companies previously , they wouldn't even talk to me about it. Sierra answered pretty quickly and Drew came out the next Tuesday to discuss it and he was like no problem we'll take care of you. He went out of his way for us in getting the papers signed as my husband works crazy hours. Drove to him at his work. They showed up right on time today cut the perfect hole to get the unit out without destroying the whole wall. Kyle and John were diligent, friendly, and focused. I appreciated that. They believe in their products and company which made me reassured I chose the right place. They kept me informed throughout the day and cleaned up beautifully. I've got a great warranty and no worries. My house is so much more evenly cooled and feels great. Thanks Guys!

I called for a Spring tune-up; cleaning and freon. My a/c was working fine.
The tech did not bring the freon; and wanted 1/2 payment up front. No.
90 degrees today; turned on the a/c tonight-and nothing.
i called and got a service; who cannot schedule.
Zero stars would be the correct rating.

This review is updated and revised. In my initial review I praised the professionalism and courtesy of the technician who came to my house and I appreciated the promptness and response of Sierra Air Conditioning. My dispute was about the price. After my Yelp review I received a personal call from Zack. Zack offered a resolution that I was very pleased with. What impressed me the most was that Zack made me feel like a valued customer and made me feel important. I've made many reviews on Yelp and this was the first time I've gotten a call from the company appreciating my review, my criticisms, and business. All around I give them 5 stars.

The two technicians, Jordan and Dan, arrived on time to inspect the AC system, now on the maintenance plan. The worked efficiently and provided a reasonable assessment of the system's functioning. They took time to explain options for improvement of the system with potential benefits as well as cost. We are happy with their work.

So thankful for Sierra Air!!! My AC unit went out last summer and they helped me out big time. It was so hot in my house that the thermostat didn't even read a temperature. I called Sierra Air and they were able to send somebody out right away.

Their pricing is very competitive but more than that their customer service is unbeatable. Since replacing my unit last year, my electric bill has dropped in half. It's instant savings!

In addition, Sierra Air sends me friendly reminders to schedule my fall and summer maintenance to ensure my unit is running at peak performance in both the winter and summer months when it's used the most. I can feel confident my unit will last much longer due to these occasional inspections.

Highly recommend. Professional staff, great pricing, and easy to book!

7/30/2022

Can not say enough good things about this company. Every tech was very professional and the service was great.
Our a/c started going out the end of last year and they made it work for us. However it finally died this year and not only did they try to fix it again but gave us a temporary motor to make it work through the heat of our summer beginning, till the new one came in due to supply issues, they were on top of it the whole way through and gave us the best discounts and offers we could get because as we all know replacing the a/c is not cheap, unless your replacing it on a regular basis. Thank you Sierra for a great job!

I have used Sierra Air Conditioning at my house and at two of our businesses, they are prompt, knowledgeable, and do an excellent job. I also received two follow up calls for follow up inspections to make sure that the unit are working properly. They even sent a painter out to touch up a small piece around my thermostat. Great company and 100% honest.

06/07/2019 12:00:00 SA

Great service from the technicians Drew and Brandon.

The only downside to this is within the past 12 months they've been to my home to service my AC 3 times. The first time it cost me about $1500 and the following routine check up which was only months apart from the previous visit cost me about $600. This time I was expecting to pay yet another $$$$ but due to their previous work being faulty, I actually paid nothing.

So here it goes - it sucks when you're AC goes down for any reason especially in the freaking summer.

It sucks when it's out of warranty and you have to pay $$$. It sucks when each time they come out it cost you $$$.

It sucks when the work you paid them for is faulty.

But then the upside is... when they figured out it was their fault and subpar repair... they charge you nothing. Not even for the service call.

So. Yeah. Good job, thank you.

Had a recent problem with our air conditioning system. We have a multi zone system and one of the zones wasn't working. Called the HVAC company we have been using for our maintenance. They came out and determined it was due to a damper not working. They told me they do not work on the zone components of a system and suggested I call Sierra Air.

Called them right after and was told someone could come out that same day. That was unexpected since our other HVAC company took, 5 days. They couldn't give me a window but said they would be out there. Around 6:00 pm. Tyler and another technician arrived. They were friendly and courteous from the start and it got better after that. I told them what the other company told me and they checked the dampers, but they also went over and above by looking at everything else to make sure that was the only problem. They found that exact problem and replaced the part. Even better, the part was still under warranty.

Great service. They put on protective shoe covering when they came into our home and spread out a drop cloth under the attic access before they went to check out our problem. Based on their service and knowledge of our type of system, this will be our go to HVAC company going forward. Great job Tyler.

There service techs are always courteous and thorough. Jose Ramirez was our recent service tech who was very helpful and courteous. We also upgraded our thermostats recently and he did a great job. He was very patient and explained everything to us. It is customer service like this that will keep customers loyal to there company.

We had Sierra give us a quote on replacing our hot water tank because Costco works with them. Ruben came out, and was friendly, professional, and we felt the price was reasonable. We were very happy with the service Ruben provided, and even though we opted to not have the work done, we will keep Sierra in mind in the future!

What a horrific disaster these people are.

They did the original install on my AC according to my builder. So when my AC unit started leaking I called them since my house was less than five years old I figured they might know a bit or give me a deal since the AC went bad after less than five years. Boy was I wrong.

The guy they sent over was not unpleasant, but for some reason when talking to his back office over the phone he couldn't give me an estimate. When I repeatedly requested some sort of price the repair guy said somewhere between 1800-3200 bucks he guessed. He promised the office would call me in the morning. Also on the way out the repair guy kicked my three year old in his face! I called them that next afternoon wanting to know how much it would really cost and why they hadn't called me. They assured me they would call me the very next day. They didn't of course.

After I called them five times on five consecutive days they finally gave me an estimate of $3200 bucks. I got a second opinion, you know what that (highly reputable/highly rated on yelp) second opinion did? They fixed poorly installed parts (poorly installed by Sierra) completely negating the need for any part replacement. And apparently Sierra flat out lied when they said I needed a new coil: about $2000 in work.

Sierra told me $THIRTY TWO HUNDRED DOLLARS TO FIX THEIR TERRIBLE INSTALL.
and then a friendly, more reputable place did it in EIGHTY FIVE DOLLARS. EIGHT FIVE.

SIERRA CHARGED ME SEVENTY-FIVE JUST TO SHOW UP!

(Okay they didn't kick my three year old, but I bet they wanted to.)

I scheduled an appointment to have my tankless water heater flushed. The appointment was scheduled for after 12pm and when it was close to 4pm, Hayden Concepcion, the plumber, called and apologized for being so late in the day because his previous appointment ran long. He asked if it was okay to come or feel free to reschedule. I wanted it done so I said to come. He promptly arrived and we talked through what I wanted done with regard to the tankless water heater as well as a couple of other minor nags--low flow rate in bathroom sink and low toilet bowl water level. After completing the tankless water flush, he addressed the other items within minutes and asked if there was anything else he could help me with. I have to say that Hayden was a pleasure to work with and very professional. He took the time to explain what he was doing and how to solve future similar issues. I could not have asked for a better person to handle my plumbing issues. It is people like Hayden at Sierra that will keep my business. He is an excellent example of an employee that represents the company in a very positive light.

Sierra was the subcontractor for our homebuilder, William Lyons Homes. We contracted for a SEER 15 A/C and a HEPA air cleaner and paid dearly for it. Upon walkthrough, I discovered that the HEPA air filter hadn't been installed. Lyons checked and I was right; Lyons went to bat for us and forced Sierra to make it up to us by installing an electrostatic air cleaner (an upgrade) with two years' maintenance. After this, I checked to see if I really had a SEER 15 unit - I did not. Again, Lyons went to bat for us and forced Sierra to upgrade us to a SEER 17 unit.

Sierra was supposed to clean out the electrostatic air cleaner every six months for two years. They came but we didn't see much cleaning, but I attributed this to the fact that the filters are in the attic (unlike normal filters). However, my wife began to say that the aircon smelled bad. After the two years was up, Sierra wanted $500 to do the six-month service. Instead I called Infinity Air (see my review there) and their tech removed the filters from the electrostatic air cleaners and showed us that they had NEVER been cleaned before. He cleaned them and guess what, the house smells much better now, my wife is happy and the aircon's job is much easier now that it doesn't have to force the air through the clogged filters.

All I can say is that Sierra was completely dishonest with us in every single dealing. Use them at your own risk.

Another great routine maintenance from this company. Timely with 45 minutes reminder before arrival. Daniel Perez was courteous, worked neatly, communicated results and findings clearly. No hard sell, which is rare, just suggestions for pro active and preventive upkeep of my HVAC units. Sierra has served me well in all of my residences

It's always unsettling when you have an unexpected problem with your AC (especially when you are selling your home in the desert...). The Sierra AC customer service rep that scheduled my service got me an appointment for the next day and she was very professional and helpful in explaining my pricing options. The customer service rep sent reminders by phone and email; I was called when the service tech was enroute too.

My Sierra AC tech, Tyrone, quickly found the problem with my AC unit. He even gave tips on preventing the problem again. Great service from a skilled, honest guy. Thanks Tyrone!

Sierra recently did a full system replacement for my home. The experience was nothing short of amazing. The timing and efficiency of the work was extraordinary. I mean everything done in a day! The quality of the customer service from the people on the phones, the technicians, the consultants, even the contractors were superior and the best. Living without AC is no joke here in the Valley. Having your complete AC replaced is a long term investment and sometimes a scary experience if you don't have the right company guiding you from start to finish. I was fortunate enough to not have any of those issues. The process was smooth and gave me a lot of comfort in making the right decisions. So my investment was definitely worth it. I also gained a better understanding of what i was investing into for the long haul thanks to the knowledgeable technicians and consultants on staff. They were very helpful and answered all my questions. I feel great now that my family can stay cool for the remainder of summer and problem free for years to come.

I bought a brand new house with an air condition unit installed by Sierra Air. One year later my unit stopped blowing cold air due to a leak causing the coolant to leak. This was repaired and I was not charged due to it being an installation error by them. One year later I experienced the same issue and was told by the tech that the first tech who came out did not fix it properly. Again I was not charged due to installation error. This being said my unit had now been operating for two years with low to no coolant in its system. The third year my compressor went out and I was told my warranty covered the parts but not the labor which was $900. The tech who came out even admitted the low coolant would cause the compressor to go out much earlier than normal, stating a new compressor usually last much longer than 3 years. I explained all this to the supervisor who did come down $300 in price for the labor ($600 out of pocket). My experience with the company was not bad and everyone was very professional, however, I did not agree with their decision and believed with my history it was a defective unit based off installation errors. I would not recommend this company based off their work and my experience with them.

Ulises came by right when he said he would and was great. He was able to figure out my issue and get it fixed in no time. I spoke to Nick as well and he was super friendly and helpful. Because of both of them, I will always use Sierra and recommend them to everyone!

I don't do 1 star reviews but this is necessary.

I called Costco and this company is the one who called. when the guy came out he had a questionnaire and when it came time to see what I'm looking to spend and afford.

First off, he quoted me 80% higher than everyone else. I didn't say anything at the time but then when he tried to close me I told him I was getting other estimates he knew he quoted me too high (he said Oh I wish I would have known that first). So he made the point to make another appt to make it more comparable. Now I get a call today that the guy is now on vacation and will have to reschedule. Who initiates an appt then goes on vacation? Did he not know he was on vacation when be made the appt? Does he not care about getting new business that he can blow off an appt to go on a vacation? Are these the type of ppl that this company hires? Does this company only have one person to handle all the work? If it wasn't for Costco would these ppl even have any business? Very disappointing and I am glad I am going with another company. AVOID AT ALL COST! BETTER OPTIONS AVAILABLE.

On 06/27/18 I called Sierra LLC's emergency line at approximately 5:45 am due to my air conditioner not functioning hoping to get a technician out before the temperature surpassed the 109 + degree predicted weather for the day as my house was already at almost 90 degrees. The emergency line told me it was not an emergency and to call back when the company opened at 7am. If your air conditioner not functioning in the middle of summer, with heat warnings, is not emergent enough to even take my name and number or to schedule an appointment, I would like to know what this emergency line considers an emergency, perhaps I should have waited for my AC unit to catch fire before calling this line.
I ended up calling another company to service the AC and from the second I called they we friendly and provided wonderful customer service and immediately scheduled for a representative to come out when I would be home. Unfortunately there was a lock placed on the air conditioner so they needed to retrieve the key. As my luck would have it, the last company to service my AC was Sierra LLC the same company I had attempted to originally call so I thought perhaps I would contact them to see if they had the key available since they serviced it last and to hopefully speed up the process as it was now more than 102 degrees outside and the house was heating up quickly.
The representative was friendly enough until I started to place my complaint about their emergency line.I was then told that they needed to verify my claims as that is not how they run their family business seeming to imply I was not being honest about what had occured. I don't know about those of you reading this, but sitting in a hot house in the Las Vegas weather is not my idea of a good time. All I wanted was to know if they had a key available and even though they are supposably running a special that allows a technician to diagnose AC issues for free, they wanted to charge me close to $50 to have someone come look at the locks on my AC to decide if they had the keys or not. After requesting to speak with a manager multiple times and them checking to make sure I was not lying about my experience with the emergency line(which surprise, surprise I wasn't), they said they would waive the fee for someone to come out. I was never able to speak with a manager during the initial call because every time the phone rep spoke with her she was magically in another meeting that could not be interrupted.
I was extremely clear with the representative that I did not want service from them, I just wanted the locks removed and verified there would be no charge for that specific service and I was told no charge. I ended up speaking with a manager by the name of Susan after the phone call ended, who also said they would waive the service fee but when the tech showed up it was a whole other story.
Not only was the tech defensive and impolite from the start (not knocking when re-entering the house on more than one occasion and smoking while outside on a phone call, so now my house also has the lovely scent of cigarettes on top of being hot and stuffy) he informed me that there would be a fee to have the key brought which they happened to have quite quickly for no one having any idea what I was talking about on the phone and them saying locks were not placed on units. Susan (the manager) even told me she asked people that had been there for 30 years and they had no idea that locks were placed on AC units.
When I informed him that I was told there would be no charge by Susan, he stepped outside to make a phone call and this is when he came back in to inform me there was a charge because the people on the phone didn't know about the locks or what it was.
So apparently even if you get verification from a manager that there will be no fee, there could still be fees and that is acceptable because as the tech said, they don't know about the units or locks at the call center...
So in summary, if you like companies that do not have a real emergency lines, lie to you, provide poor customer service not only in the call center but also in person, and on top of all of that have techs that smoke outside trailing their stench into your house; this is the company for you!

We used Sierra Air Conditioning the first time we moved to Las Vegas back in the 1990s and loved their service. What I liked most was, if you're on a maintenance agreement, they call and schedule you every six months...like clockwork!

We moved back to Las Vegas recently and again, decided to use Sierra. They continue to amaze me with their integrity and high level of customer service. Josue was our technician this afternoon and he stayed until 8:30pm to make the needed repairs to our HVAC system. He never complained or made us think we were interfering with his Friday night personal schedule. Again, Sierra continues to be the best IMO. Highly recommend.

Called last night about water heater breaking. Lady said they would call back at 8:00am today. No call, no show. We use these guys for all our air conditioner needs for years. We used to use these guys. When loyal customers get the cold shoulder, the low ratings and reviews start to make sense...I called a 5 star, they came in 30 mi

RJ-We submitted a yelp request for help after your office didn't return our call at 8:00am the next day, as promised. That's why you received an automated contact from us, the morning our call wasn't returned. It wasn't us trying to get you to respond, it was automated via yelp. We went into panic mode after you guys couldn't keep your commitment from the day before...a guy did come out for you guys, gave me a $1200 estimate, and a schedule date for a Tuesday (2 days). We got it done for $600, the same day, with RUUD equipment, and a warranty.

Total rip off... very dishonest employer. I was charged over $2K for something I didn't need. They disconnected wires and reconnected them in a wrong place. They also suggested to change the entire AC system in my 3 year old home and quoted me over $15K to do all the work. I consulted a different company and fixed my ac in less than 1 hr and charged me less than $400. Stay away from Sierra and I recommend to seek local family-own business and compare prices before making final decisions.

I scheduled an HVAC semi yearly maintenance. The technician, Nikas came early which I didn't mind at all. He did a thorough inspection of my system and even took pictures of the HVAC system. He explained to me how all the different components of the HVAC system worked which was very helpful because I didn't have this in Hawaii. I ordered a few modifications to the system to make it work more efficiently. Although it took longer than the estimated time, I can't complain cause those kinds of jobs you just can't rush. I'm an aircraft mechanic so I should know. Overall I was satisfied with the job done. Kudos to Nikas!

During the hottest weekend of the spring, our ac system just stopped, about 9 pm. Literally sweated it out, till 830, called and was scheduled for service call. Dispatchers were patient, and empathetic.

I was assured that the tech would show up. At 1900 Tim And Tony showed up, I described the symptoms. 10 mins later we have cool air again. They showed me the old part, where it came from, answered questions and were very friendly.

Sierra is on my permanent TO CALL LIST. For heating and air!

Very professional, worked quickly but took the time to explain exactly what he was doing and why. Also, he didn't use any high pressure tactics to up sell products. He simply explained the pros and cons of each option and allowed us time to decide what we wanted.
He was also very personable and courteous. Enjoyed talking and interacting with him.

Had a great experience with Vincent from Sierra Air Conditioning & Heating today. Vincent performed our seasonal air conditioning service and explained critical service points that need attention as we move into the hot summer months. We are new to the Las Vegas area and Vincent's attention to details and clear explanations provided additional value beyond the routine schedule maintenance. We are happy Sierra Air Conditioning & Heating customers!

My A/C unit went out on Saturday and the Sierra Air Conditioning tech arrived at my home within hours. He was wearing a mask (much appreciated) and quickly diagnosed my problem. My 22 year old unit required replacement. The tech explained the problem in detail. Ryan followed up and they were able to provide a temporary fix until the new unit was installed. Superior product, service, and installation. I highly recommend them.

Great company that I would highly recommend. Top notch service and they stand behind their work. Very mindful and courteous especially during these times where social distance is on everyone's mind. They provided an evaluation of the system prior to leaving and options for how things could be addressed. Able to feel educated without trying to just feel sold. Always nice to stay informed.

If I could give negative stars, I would. I've had the absolute WORST experience with Sierra.

Beware of and ready for lies, upselling, and a flat out ripoff. The tech that came to conduct our semi-annual SAM inspection told me that the amp draw on 2 of our units was far above the manufacturer's recommended maximum, indicating the motor and capacitor were overworking to start up such that we'd need hard start kits at the price of $600 each (x2).

Trusting him, we agreed only to find out that the part is $50-60 online, and YouTube shows you how to swap it out in about 10-15 minutes. As it turns out, after getting a second opinion, it turns out the tech was showing me a different number on his meter to make me believe the amperage was way higher than it was, which was well within the appropriate range.

Additionally, he charged me more than $300 to seal a duct in a location inaccessible to me, and the same company from which I got the second opinion showed me pictures that Sierra's guy didn't even use sealing putty/mastic; he just duct taped and zip-tied the freaking thing.

I will NEVER use Sierra Air again because I feel they cannot be trusted.

Amazing! Very polite! Ryan H. Helped us with the purchase of our new unit. He was extremely knowledgeable. Unit was installed last week and it's been great! Much quieter than our last unit. Install team was great and left no mess! Great experience!

OH man! What can I say. These guys are literally my heroes. One late night, I woke up to my AC blowing warm to hot air. I woke up drenched in sweat. It was about 1am, and the heat was just unbearable. I decided to contact these guys and they serviced me right away. I have never been so moved by the amount of service, knowledge, and professionalism conducted by these guys.
I'm born and raised in Hawaii, and I noticed that this company is full of 808s. Even more I felt like they were my extended family away from home.
I want to give a HUGE shoutout to Damari and Derek. Shoutout to you guys for dealing with my emergency that night. If it wasn't for you guys, I probably would have slept that night in my car, running the AC like crazy. Thank you guys so much.
I DEFINITELY recommend for everything!!!
5 stars and everything: service, professionalism, products, customer service, patience, and knowledge.

We have been on a service agreement with Sierra Air for 6 years now, they started when our home and AC unit were brand new and we have never had any issues with heating or cooling during the entire six years. At each service they make any recommendations and provide an estimate if they see something that could become an issue but they are not pushy about it. Today we had a regular summer AC checkup, our tech was John Morgan and he was on time, very professional and polite. My wife and I highly recommend Sierra Air! 5 stars!

Another great PM service provided by Tyrone. He has been our preferred technician for 3 years now. He is always on-time, polite, and informative. We appreciate his honesty, has never gave us false information and we know this because we own and operate an HVAC/refrigeration company back home in Hawaii. As long as he is employed by Sierra, Tyrone will be our guy!

I had my air conditioning unit stop working the first time I tried it this year for cooling... As promised they sent someone out David who in less than 5 minutes figured out the problem an air booster motor ( I think that was what he said). It took a day to get the part and come back, again it was David who did the work and is a friendly person easy to talk to and understand. He had it up and working in about 15 min and all of it was under warranty and cost us nothing. That was great, if you use them ask for David although I am sure the other people who work there are also very good I enjoyed my experience with David very much and wish the company and David well for a job done with experience and a friendly manner.

Happy to still recommend Sierra A/C & Plumbing . We had an unusual problem with our air conditioner. Starting the hottest days of the year, right before 4th of July holiday and no part in town, Harry was able to diagnose the problem, order the part on the 3rd and we were back in our house on the 7th. Sierra could work better at communication to let us know the part was ordered and give us an estimate time of delivery. I had to call every day to check the status and probably would have had to go through another weekend without A/C if it wasn't for the daily calls I made to ask if the part was delivered and I could schedule the work. Overall, I'm still happy to recommend Sierra A/C & Plumbing after a hectic and frustrating situation.

1 star since I can't give 0 star for service, however I would like to give 10 stars for SCAMMING customers. $89 for someone to come and diagnose problem. Then they charge labor fee to fix each problem since parts are under warranty. So if they find 5 problems, they will charge labor fee ($288) 5 times. Customer service explanation was because parts are still under warranty!! So I'm expected to pay more in labor since I'm not paying for the parts? In my opinion, I should only pay 1time labor fee to address all problems found doesn't matter if parts are under warranty because that is what the warranty is for. If this is how they do business, don't give warranties since they say they are an up front company.

My upstairs air condition didn't work and I found this company through listening to Pandora Radio station. The service tech Brandon Brown showed up. He was very professional and knowledgeable. He diagnosed the problem correctly and solved it. I was very impressed with his expertise and he educated me as well. As a result, I signed up with this company to do maintenance so I don't have to worry about problems with my air conditioning and/or heating. Let the professionals take care of it! Thanks Sierra for sending Brandon to do a great job! I would recommend your company to anyone as I was very pleased with the results.

4 years ago I had Sierra come replace my water heater. On Christmas Eve my water heater broke and I called to request that they come out and look at it. The tech arrived and told me that he could replace it but that the warrantee work would take several days. He told me the cost would be $1400 to replace the water heater with a new one through the warranty. He then told me if I wanted a water heater that day, that I would need to purchase a new one for $1600 for a total of $3000. He told me that the water heater was purchased through Ferguson plumbing. I called Ferguson plumbing and they told me that they would switch out the warranted heater for free and that they were open until noon. I asked Sierra to leave and then went down and switched out the water heater for free. I took it home and put it in myself. The best part is that I was in my fire department uniform and he still had no problem trying to rip me off. If they will rip off those that take care of the community, I'm convinced they will rip off just about anybody. Thanks Sierra for nothing.

I have utilized the services of Sierra Air Conditioning & Heating to install and perform maintenance on my home's heating and air conditioning equipment over the last 20+ years. Today they performed the the annual maintenance on my home's equipment. As has been my experience with them in the past, i was impressed with the technician (Ulises) that came to my home today. He was very professional, knowledgable and took the time to explain and show me what he was doing and the results of the testing as he performed it. I can't speak highly enough of him and my overall experience with the company over the years. A perfect 10!!!!

Our AC broke over night and we didn't know what to do. So my dad called Sierra LLC because that's the company of our AC at home, and let me tell you I'm SUPER HAPPY that my dad called them! We thought they would be closed today because it's a holiday, but they weren't! I don't know if my dad called them yesterday or this morning, but they were quick to respond to us.

Joshua was very helpful AND FIXED OUR AC IN LESS THAN 3 hours!!!!! To me that is fast because I assumed it would take at least a week. He ensured that we understood everything that he was talking about, and the quality of service that he offered was excellent! Thank you, Joshua! I'm all comfy and comfortable in my home :)

we just moved to Nevada 2 months ago. of course had to be hottest weeks out here. 95 degrees still at 1130pm, thermostat read 85 in the house. A/C stopped working.
Luis, serviceman dispatched to us was amazing. Outstanding service, explained everything in full detail, gave cost of parts and labor before service was performed.
Wound up being the capacitor, which was dead, caslusing the compressor not to start. Luis was professional and thorough! thank you Sierra LLC air conditioning and heating.

Our AC went out during a heatwave and I called Sierra. They were able to fit us in their schedule same day. Daniel arrived and was very nice and professional. He tried very hard to find a solution to fix the unit without having to replace an expensive part and explained everything in detail. We ended up needing to replace our compressor and Daniel continued to follow up with us the next day letting us know the status of the part and was determined to get it installed for us that same day. Fortunately the part was still under warranty and Daniel was able to get us a good price on installation. We are very grateful for Daniel for getting our AC back up and running so quickly!

This review concerns my hot water tank. I was at Costco and noticed they deal with such products. 8.5 years old is my existing tank. One day it didn't produce really hot water. Next day it was back to normal? Costco offered a free inspection. I was pleased to get the call from Sierra. I had used them many times before, for my aircon and furnace needs, not always great service. I requested a technician who knows his stuff because they messed with my furnace a few days before Xmas a few years ago and I froze those days. Anyway, Reuben arrived very early the next morning. He inspected the tank and gave me several options:
1) flush the system for $75.00 after noticing some rust on the top of the tank. Great, let's do it. He couldn't because there was a plastic hose attachment and he might break the unit!
2) tune-up for $810.00!!!! I could buy a new one.
3) replace for $2349.00!!!!! Wow, that's pricey.
I really felt I was being scammed. He must work on commission.
Would love to hear back from the owner, but then, he only responds to the 5 stars reviews.
Must let Costco know these results.

Be Careful!

Last year Sierra installed my new HVAC system and I couldn't be happier. Yet, a year later, I am wishing that another company was used. It was time for my yearly service appointment and at the same time I was having my filters changed. I made a call to set up my appointment on June 11 and the soonest they could come out was July 3. They arrived and started the service. I made a comment about the filters and the service guy stated he didn't have it on his truck. He was not told it was part of the service. Yet, when he looked back at the notes from my original call he stated that he should of been given the filters. He told me that I would receive a call on Monday about scheduling the filter installation. Monday came and went and nothing. I waited until Friday to give them a call. They claimed the part was on order and they would call me when it got in. It has now been four weeks since I originally requested the part. No part should take that long. I once again wait for another week. They called and set up an appointment for July 21st between the hours of 2-6. I spent the day at home waiting. 6pm came and I called to figure out what was going on. I was informed that the serviceman once again did not have the part on his truck and would have to go pick it up and it would be at least an hour to two before he would arrive at my house. I am sorry but an 8pm service call is completely unacceptable. I told them it would have to be rescheduled. They did come out today and replaced the filters. There are plenty of other HVAC companies in the valley. If they can't even order a basic part I would be hesitant to let them work on my system.

Sierra will not quote any price without having their technician diagnose the problem. They charge $75 for a diagnosis.

They improperly installed my system only 4 years ago. Their improper installation led to the failure of the compressor on my A/C unit, yet they will not quote a price for a warranty repair unless I pay them $75 to diagnose it. I told their representative exactly what the problem was, and exactly the service that I wanted them to perform, yet they insist on having their technician look at it before quoting a price. Even though they installed the system, they will not waive the $75 fee.

This company installed my air conditioner on a new build. The system is less than 4 years old and went out just the other day. I called to get someone to come out on Saturday to repair it. Reached them at 6 am to get someone to come out and was told that the on call technician would call me right away. Never called. I called back and was told that they didn't have any record of my call. Scheduled something for their first available 4 hour window. The tech arrived and was courteous and knowledgeable. After 40 minutes the system was blowing cold air again. 2 capacitors burned out but they were under warranty. Despite that, the bill was $380! For 40 minutes in labor. The diagnostic fee and almost $300 for 40 minutes worth of work. I had to use this company because they installed the unit and have the warranty information, but you don't. Steer clear! One star.

Update: received a call explaining that they were both training issues. The representative was professional and courteous. Very responsive. I can't help but wonder if I hadn't known the charge was too high if they would have caught it or if I would have been out $160 bucks... still, they responded quickly and owned the mistake so I can't, in good conscience, leave them with a 1 star review.

Just had my Bi-Annual Summer service for my home's HVAC and Francisco was sent to my house. He was professional, knowledgeable and courteous. At the beginning he called multiple times but I missed the calls. When I finally called back, he was out on lunch. After 11 minutes, I got a call back and was told that he was on his way. When he left after the service, he later called back to remind me to secure my side gate. Thank you for a great service.

Sierra is a well run business. We have a maintenance program with them where they do the work... remind us it's time schedule apt and show up. Our technician Matt B. is incredibly kind courteous and knowledgeable. Having contractors in the house is definitely a inconvenience but he made it painless. Thanks Matt!

We just moved into our new home and needed help with setting up the thermostats. Sierra HVAC installed our systems so I called them and within a day Matt and Vincent showed up. They were patient and kind to show this non-technical senior citizen how easily they can be set up with WiFi. Since they were here I had them change the air filters to HEPA quality standards. The filters are superior to what was put in and we believe they have improved our breathing. I highly recommend Sierra.

If I could give 10 stars I would! I highly recommend using this company. I had the best experience today with Tyler. He went above and beyond to explain the services performed in great detail. He was super friendly, and very knowledgeable. I even signed up for their maintenance plan which is a huge $$$ saver! I can't believe I had such a great time having my HVAC system serviced today (lol). I'm even having them handle my plumbing needs moving forward. Thank you Tyler & Sierra Air for making my life easier. :-)

I really like them as a company. I have three homes on contract with them so like their service.

I was bothered though today during a routine spring service call. A $245 estimate to replace a $20 capacitor in the evaporator (indoor) unit for the fan motor.

Come on guys. This just reeks of up sell and gouging. The tech has the unit open. It is about 5 minutes to swap a capacitor not requiring special equipment or special training.

If this keeps happening then I might look elsewhere. Do NOT gouge or up sell me. I am your customer with 3 service contracts, so you do NOT need to be greedy.

Refused to cover new home install warranty issue because I never called them with a problem. Being new to purchasing a new build I used a home warranty company to check the air flow issue. They informed me that the HVAC was installed incorrectly and should be under warranty with the installer that Lennar used, which was Sierra Air back in Oct 2016z so when I reached out to Lennar they pushed the issue to Sierra Air, who told me to send a copy of the 3rd party report. When I did, Sierra Air called me back and said my issue was not under warranty due to never calling them in the first place. I wasn't aware this was an install issue and never thought the warranty was still in effect. So now, which out even offering to come look at the problem and stand behind their work, they kicked my issue right to the curb. When they called me, I was with a client and could not dive deeper into the issue at hand because it wasn't going to be appropriate at the time. Sierra Air lied to me when I first called them. I sent a picture and the document from the assessment of the home warranty repair tech who only looked at the issue and recommended a different air filter. They didn't touch the duct work. Sierra Air doesn't give a you know what about their customers and makes ZERO EFFORT regarding customer service or their reputation. I have worked 30-years in retail as a Regional Manager and have never been involved with this type of negligence in my experience. Currently I work in a service department for a large corporation and I can promise you this, I will NEVER RECOMMEND SIERRA AIR to anyone who inquired about I air conditioning or heating...NEVER!
I AM SHOCKED by Sierra Airs 0% of effort and customer service. Extremely dismissive, unaccountable and 1000% criminal behavior. DO NOT USE SIERRA AIR!!! They do not have your best interest at heart. Very disappointing! My air conditioner is only 4 1/2 years old and works fine. Except where the install is CHOKING off the air to the front of the house because they installed one section incorrectly!!! They won't even come out and look at it! Can you believe it! I think my head is still in shock over what the lady told me. And she truly couldn't give a you know what to the problem. Of course she offered to transfer me to the department to schedule someone to come and fix the issue as she reminded me this would NOT be under warranty!!! Are you kidding me! Why in the world would I pay to have the scam of a business come to my home and rip me off more! That's like asking for another slap in the face! If they truly cared about their work, they could come out on their own dime. (Aka warranty) and inspect it themselves! But that of course is NOT an option for this route 91 survivor and single mom who only tried to fix a problem the best way she could. SHAME ON YOU SIERRA AIR! SHAME ONE YOU!

Save your money on their one year maintenance. They will sell you their maintenance service to give you a discount on their job. Wait til you make an appointment for the maintenance and gives you a time window. They only show up if they have time for you. Happened twice! Had to re-schedule for the summer service and now for the winter service.

Definitely not hiring their services again! I trusted the company since they have partnered with Costco. Very disappointing.

I am SO extremely grateful for this company!!

We had been waiting over a week for our AC to be fixed through our home warranty (First American-do not recommend!)

Our son has disabilities so we are unable to get a hotel due to specific things we need in the house for him so we needed it fixed ASAP.

After over a week of waiting for other companies to come but no availability, being told they couldn't fix it that day, or being rescheduled we were finally able to get authorized to use anyone and be reimbursed by our warranty.

Within 3 hours of calling on a Sunday Sierra AC had a tech out here. In less than an hour of being here Francisco had our AC fully repaired & running again.

He also explained what problems we might have in the future (due to it not being repaired for over a week & just the age of the AC). He was so nice & reassuring. He double checked the temp upstairs & downstairs before writing up the paperwork.

It can't even explain how happy i am to have our AC up and running again (in July)!!

Highly recommend this company!!

A special shout out to Jonathan C - we had to reinstall our ac as part of a pool project (not a Sierra issue) and Jonathan was here to do the job! Stayed very late on a Friday night to finish the job. Highly recommend the company and the team!! As Jonathan said have a cool summer! We will - thanks you!

So we've been customers for 3 years now and pay for their SAM maintenance contract which is supposed to give you priority service. Both our AC units went down on a Sunday. They are 3 years old. We just had maintenance end of May.
Its 115 degrees right now, so we called for an emergency service, something we thought we were a priority for under their program.
it's now Monday, at 5pm and we are STILL waiting. We've called 3 times and were told we were next but the technician wasn't done at his previous call. We've been waiting here - ALL DAY.
So in comparison to any of our service contracts back east, this is a joke.
Sierra might be fine if you aren't in a hurry for service, but in an emergency, you are basically screwed.

What is it about service companies in this area ? Not a phone call from them all day. same canned answer every time we call.
I cannot believe that people accept this level of poor service.

we are certainly looking for a better alternative. Too much money to be now held hostage for 28 hours now waiting for a tech.

The technicians were great! We are part of their plan so we appreciate their service. For our a/c check recently, they said we could use a new capacitor... but it wasn't absolutely necessary at this time. We know nothing about the cost and difficulty to install, but figured it was good to get it done. It was $280ish all in with the plan discount. I found a capacitor of the same type online for $22. Appears we paid $258ish for the install. Not happy about the overkill on the cost as it seems to be a pretty simple install. We may keep the service ($25 a month), but will most likely never use them for the fix it service. Very much a shame.

I had quite a project for Sierra Air. Had a new water heater installed and repiped. Then an entire replacement of my
old aqua therm air conditioning unit. From beginning to end all quality. All the techs, salesmen, installer and inspectors that came to my home were knowledgeable and professional. Always courteous and answered all questions. Never left without making certain everything was in working order. I will be a loyal customer.

Garbage service. Technicians claimed I had a leak in my AC system and I paid there service fee, they told me it was extra to find the leak an extra $600 charge. I called another company out and they serviced my AC (refilled the refrigerant) for a fraction of the cost with no leak indication and my AC now works great, better than it ever has.

I called a week ago to set up an appointment to get an estimate to replace my AC units (because another well known company said our AC was on it's last leg). The first mutual appointment time was a week out between 4 - 6p. My husband rushes to get home and waits and waits. I arrive home around 6:30p and nothing. No one called and no one showed up. I called and the lady was like oh we've been crazy busy with the heat, let me get a hold of dispatch and find out where they are and dispatch will give you a call. Dispatch calls and now they had computer issues and they could get some one out on Thursday. WHAT!? How did you make it to all your other calls that you were crazy busy if your computers were down. Then to top it off you wait until 24 hours AFTER my original appointment time to call and apologize and reschedule for tomorrow? I asked about the inconsistencies between the two stories and she said that was probably the after hours phone service (she never once said she was the answering service and I have called other businesses and they always state we are just the answering service - which leaves me a little leery). Maybe a phone call first thing this morning I would have been a little more inclined to give you a second chance.

Thanks, I'll go with the company #2 that showed up on time AND sent a tech out for free to verify whether our ACs really did needed to be replaced or could simply need a quick fix.

Best of luck to you if you use this company, hopefully they show up for you!

Our technician, Darryl, was awesome. He was professional from the get go and was on time. He even wore booties over his shoes which was very considerate. Darryl was extremely knowledgeable and explained everything very eloquently.

Our downstairs heater wasn't working before he arrived. He went up into the attic and took a video of the problem with our furnace. He went out to his van and retrieved a new replacement item and changed it right away. I am no longer freezing!

This company pricing is fair and affordable. I will always call Sierra Air if there are any future issues. Thanks Darryl!!

We've had Sierra come out a couple of times to do routine maintenance on heating & air conditioning units. This time a tech named Eric O. came out and was he super! Very pleasant to speak with and very knowledgeable. He told us our unit was in good shape and made some suggestions about different things we could add-on but didn't overly sell it. Which was nice. He kept the area he was working in clean - no dust or insulation fuzz anywhere. Plus, he didn't mind our dogs jumping to greet him.

We will definitely be using Sierra for all our heating & air conditioning issues and Eric O. is the only tech we'll be requesting!!!

AJ was great, fixed the problem, cleaned up, and checked out the attic part of the unit. He went above and beyond.

I highly recommend their monthly maintenance program. They come out twice a year and clean your AC/furnace system. Jonathan from Sierra recently came out to service our system and was amazing! I can't thank him enough for going the extra mile to answer all my questions. He really put my mind at ease knowing that my system is working perfectly and made some great recommendations.

We came home to a WARM house after an hour long baseball practice OUTSIDE on a Saturday afternoon. It was a long holiday weekend and the temperatures were in extreme heat advisory conditions. After calling and speaking with Kim, who was very sympathetic, polite and helpful, she said she could get someone out that night but it wouldn't be till late. After waiting till 10pm, I have her a call back and asked if someone could come by in the morning since my son had just gone to sleep. She then gave me a window of 10-2pm.
At 9 am the next morning I got a phone call saying that someone could be here in the next 20-30 minutes!!! Liam was our tech who serviced us. He was very professional and kept me updated every step of the way on what he needed to do. The whole thing took maybe an hour tops, because of the part we needed not being on his truck. I'm the end we signed up for the maintenance club that is more than worth it for the peace of mind.

Sierra arrived to conduct a 1-year service check on our hot water heater. I was met by Ruben who did a fantastic job. He explained what he checks prior to starting the service and walked me through on how to extend the life of a hot water heater. Those of you that have a water softener know the challenges it creates with a hot water heater and leaks.
Ruben then proceeded to conduct the service checks as he had previously outlined and finally conducted a post service discussion.

Very thorough, very polite, right on time, and informative. We'll look towards Sierra and Ruben Dominguez for all our plumbing service calls.

Nice job!

Called to arrange a date/time for a technician to come out as busy schedule for both technician and me; each time I called, they
- answer phone calls right away
- are professional
- are kind and understanding

The technician did come out and fixed it
- on the day/time
- professionally
- was very helpful

Yes, I was frustrated, but they resolved it.

Our A/C had went our yesterday, so we called Sierra to come out and service the unit. Not only did we get same day service, but the technician they sent out was amazing!

Jose was very transparent about what he was doing to our unit and took time to educate me on the process. He discovered that our capacitor had went out, causing the compressor to not engage. He replaced it and got us with cool air again.

These guys are out here saving the city! It's easy to take climate control for granted. I highly recommend choosing Sierra.

Our AC died in the middle of the night. Having used them through Costco in the past we decided to use them again. We called early in the morning. They were able to come out before lunch time. Instead of putting too much money into our old system we decided to have it replaced with a newer more energy efficient system. They found a unit out of state and got it transferred quickly. They were able to get everything done quicker than we expected. Everyone was professional and answered all our questions. They will be our preferred ac service provider from now on.

The people who work for Sierra are tops. Starting with Drew for the initial consultation/sale and the two tech's, Hugo and John were awesome! From start to finish, they were helpful, friendly, considerate, polite and knew what they were doing.
We had a total replacement of the condenser, plenum, furnace and nest thermostat. They weren't the cheapest, but not that much more expensive, (we used Lennox) but with what they did and the followup they will be doing for two years, they aren't a hit and run company. We had three other bids, and trust is a big issue for me. They gained my trust, we left the house while they were working and never had a second thought.
They were on time, thorough, and finished the job in about six hours. Neat and clean, they did the job right. There is some sheetrock work that needs to be done, the opening wasn't big enough for the furnace. That will be fixed in a couple of days by Sierra.
If you need a reliable company, give Sierra a call. 702-798-1055

I'm way over due for a review. I'm not going to lie I been using this company for couple years and have nothing but positive things to say. The customer service is good. All the technician i came across is professional and great. But if it wasn't for Melvin Guerra I wouldn't put a post. Shout out to Melvin Guerra for being a good, responsible, reliable technician. He was very throughly and did a fantastic job on my tankless water heater. I will know who to ask for when I need you for any other repairs. Thank you Sierra LLC Air conditioning & Heating for having Melvin Guerra in your company he is awesome!

Buyer beware
I signed up for the seasonal checkup of my air conditioners. What a farce, the guy used a spray bottle of chemicals that was supposed to be $360.00 chemical treatment. Then the service worker wanted to up sale me a start assist kit because my system was using more amps that on the recommended startup. He didn't mention that everyone around me had their air conditioning on which was taking a lot of the voltage in the area driving up the amps required to start the air conditioners. But anyway he just happen two have two start assist kit in his truck and could put them on for $560.00 for each air conditioner. The cost of the part is $27.50 on Amazon with a two wire installation. These are the worse kits to put in your air conditioners unless they are not starting PERIOD!!
This company will never be called back to my hone they should be a shame of themselves for up selling of unnecessary parts.

Outstanding company. My split A/C & heating system inspection revealed my 12 yr old larger unit was nearing end of its life cycle. Sierra's consultant Jeff was most professional and honest. He showed me the defects and explained everything and provided me options from repair to which new split systems best matched my home. I have never had such professional service from from any A/C company in over 30 yrs of owning homes and rental properties. I decided to have Sierra replace my larger split system. The team doing the install were all professional, friendly, and answered all my questions during the process. I observed the A/C removal/install outside, furnace in my attic and thermostat replacement. I have never been so impressed with the professionalism, knowledge and experience of both David and Bryan during the installation. I highly recommend Sierra Air Conditioning to anyone seeking an honest, no pressure evaluation and an installation that is far better that you would ever expect.

I have used Sierra air for 3 years for maintenance and a new HVAC system on a 12 year old property. They were the company my new home builder used to install the HVAC system. I have had them come out a couple of times for maintenance at my new house and the techs have always been very helpful! Recently, I went to Lowes for a new HVAC system and Lowes sent out SIerra air. They replaced the AC and heater in my 12 year old rental property. I feel like they are honest, they treat both of my properties with respect, and their pricing is fair.

Our annual AC maintenance was scheduled later than usual by my not setting an adequate reminder. Won't happen next year. :)

During Mathew Parayno's maintenance on 7/12/23, very late in the day, his 10th call of the day, in very high heat, over 105, he found the unit in the attic to be functioning fine and made a suggestion that the winter heater maintenance be scheduled prior to Thanksgiving, after the weather outside chills a bit.

While doing maintenance on the outside AC unit, he found the startup amps were too high, harming it & reducing its potential life. We accepted his recommendation to install a high startup package.

It was quite late when he finished, having done 10 calls today & having worked thru the weekend. His demeanor was excellent as was his professionalism. We want him to do all future maintenance calls!

As fate would have it, on a holiday, our heater went out at my daughters' house where we were staying over New Year's weekend. The warranty had expired and the heater simply wouldn't stay on. It would fire up and then die. Ulises Hernandez the tech that came on New Years Day was outstanding. I descibed the scenario and up he went into the attic. Within minutes he showed me the cause of the problem...Pidgeons! They were pooping down our exhaust spout and clogging the necessary filters to run the unit. He cleaned everything out, didn't try to upsell me anything. Described the problem, found the solution, fixed it and off he went. I HIGHLY RECOMMED Ulises, he's a class act, knows his trade, extremely professional and Sierra LLC is fortunate to have him as an employee. Thank you Ulises, you made my wife very happy which in turn made my holiday. Much appreciated. Chris McMahon, Paradise NV

Tyler was a wonderful technician. He was 15 minutes early for our appointment. Explained things clearly. Did all that he said he was going to do. Cleaned up after himself. We could not be happier, well if it was free we would be happier, but that's beside the point. We will want him to service our HVAC units again.

Jose V Ramirez was our service tech he arrived with his mask on ready to work. He was very professional and hardworking. He answered all of my questions and explained everything he would be doing step by step as well as showed me everything he would be doing. Jose did excellent work and they have a great savings & maintenance plan. Don't hesitate if you need service please call them and ask for Jose to come out and service your home he is the best!

Mr. Longoria, Antwonn, and Ruben (plumbing) were professional, courteous, and diligent in the installation of my AC unit. They took the time to answer all of my repair-related questions, and ensured that I was comfortable with the installation. They even spent some time explaining other home improvement projects that I have been considering. They truly provided a Disneyland experience today.

Being a Flo-grown and moving here to Viva Hot Vegas, AC is always of the highest priority to myself and my family! I have been very happy with the service we've received from Sierra AC. The staff is very flexible with maintenance scheduling. The techs who come out know their stuff and explain each steps of the process as they went through our system to make sure everything was in working order and in terms I understood (which are super simple ones.) The techs even take the time to cover their shoes to be respectful of our flooring in the home, as well as to shut doors to keep bugs and hot air out of the house. They were friendly to introduce themselves and even took the time to entertain my kiddo and pup. We've had Matt and Kyle out who are very knowledgeable and thorough so that we have no worries after they leave. I like their honesty and understanding of the HVAC system because we all know that you can't afford to have no AC when it's over 100 out in the Vegas Summer!

Tech was late for the very first visit. I had to personally call them to inquire after my 4hr window time had already passed. They informed me the tech was running behind. I let it go, even though I was not happy they couldn't call me to inform me. Bad customer service. After seeing the tech for a diagnosis of my unit, I scheduled a second appt to repair what was suggested. On my second appt, I was scheduled between 12-4. I fell asleep on my couch waiting for a phone call or knock on my door, which I did not receive either. It was 5:30 when I woke up and I hadn't heard anything from them. So, I personally called again, like I did my first visit, and the girl couldn't really explain what happened only that she would reschedule me. I denied and hung up. I received a call from Susan, supposedly a manager, I missed her initial call and called back. She has yet to call me back. Horrible experience! I had a referral lined up, too, I let them know right away my horrible experience. I found another company.

Please people do NOT get ripped off by these guys. Came and said our blower motor was bad on our system. Then told us it was going to be 1,100 bucks to fix it. When I asked how much the labor was and how much parts were the technician couldnt tell me. They carry a book with various prices to fix different HVAC systems. The page they show you will have the name of the problem and just a price. RED FLAG !!!
This is like 600 bucks overpriced based on our model and tons efficiency etx. Dont get jacked up. These guys are rip off artists!

Our Water Heater starting leaking so we called Sierra on Saturday of the Memorial Day Weekend and they came out that day. We were more than pleased to see their technician Rueben show up to take care of our issue that very same day. Rueben had been our technician previously when we installed the water heater and he did wonderful work then and he did an excellent job again this time for us. Rueben is quite a wonderful person and he is VERY VERY GOOD and he is VERY VERY THOROUGH about his work. Rueben is very good communicating what issues are at hand and also at explaining solutions that are available. He works efficiently and neatly and cleans up after the job is completed and leaves behind an environment better than it was before he arrived. We feel very confident that the job was done right after Rueben gets done with it because we see it in his work routine and his desire to do things right.

We feel very satisfied with Sierra's service and hopefully if we need service in the future Rueben is the one who shows up to save the day !!!

Thank You Sierra and THANK YOU RUEBEN !!!

RIP-OFF ARTIST. Had a friend, that is an A/C repair tech, look at my units and tell me my compressor was out on one, and added 2lbs. of freon to my other unit. I payed the $75 for their diagnosis to get them here, even though i knew what was wrong. They quoted $4000 for the new compressor so I told him to leave, he said he added 7lbs. of freon to the other unit, without my say, and gave me a $495 bill. I said i was not going to pay it. He said they will send me to a collections company and mess with my credit... . so i payed..

So 7 years ago Sierra installed a new a/c Thur Costco and I couldn't be happier till today. Thought Costco I have the come out today and tune up my a/c that they installed. So at about 11 am this young man shows up as clean cut and courteous with perfect customer service skills. He showed me what he was going to do and the price of course I agreed and for the next hour this young man worked even got up in my attic and did whatever to the air handler (which no one ever did before)now
I know why they have been in business for so many years. The young man name is ulises and what an asset to this fine company.
Are they the cheapest No but if you want great workmanship for a fair price this is it. Oh Thur Costco this service was less than anyone I've seen.
Keep up the fair and honest work it's refreshing and thank ulises his folks did a great job

I am impressed with Sierra Air. I have received service twice from their company. I appreciate the care they take in your home--wearing shoe covers and placing a drop cloth on the flooring before setting their ladder down. (And they bring their own ladder! I've actually had an HVAC technician ask to borrow one. )
Tim D was extremely polite and professional. He was patient in taking the time to discover the problem I had called about. 'Cause wouldn't you know, the sounds I had been hearing weren't happening when he got there. He really took the time to figure out what might be causing the concern I had. I'm glad he didn't give up because he finally got to hear what I had been talking about. He had assured me that the problem we were having would be resolved that day.
He also addressed another smaller concern. And he gave me tips on setting my thermostats and the types of filters I should use.
Give Tim a bonus! :)

Called them up and they managed to get someone out here the same day which was great because it was 105 outside. Jonathan showed up and went through everything until he had a full understanding of the problem and explained our options to us very clearly. He was super clean with face mask, shoe covers, he even laid down a tarp where he was working inside so he could take the mess with him. Long story short, we were really satisfied because he got us back up and running for a fraction of the cost we were told to expect by other companies we had called. Thanks Jonathan !

Our heating unit broke down at our house and Sierra sent a couple great guys, Jonathan and Grady, over to triage and fix. The two gentlemen were nice and respectful of my family and house. They were able to immediately diagnose the problems with our heater, explain the problem in laymen terms to me and even provided picture and video of the issues with the heater in my attic. They went so far to send the pictures/videos to me for my files. The fix was immediate and just in time before the winter weather settles in next week.

They even gave me additional advice on installing smart thermostats in my house and gave me safety tips on powering down the FAU breakers before installing. Jonathan and Grady were great guys, with good information about HVAC systems. I totally appreciate their respect and customer service. These are good guys you have on your team, Sierra Air!

We were not looking forward to the process of buying new air conditioners due to huge investment. However, Thanks to Ryan Hernlund, we just had the best experience. Ryan is the most knowledgeable and honest sales advisor we have ever met. He took the time to thoroughly answer every question that we had. His overall knowledge on their product, warranty, service, contract, and all the other questions we threw at him, was very impressive. He went above and beyond for us and we will definitely recommend Sierra to others!

Another summer and the pipes to my AC froze over again. Turned the AC off and called my home warranty. Of course the people they suggested didn't call and we tried to call them. No luck. I called my home warranty and said I'm call SIERRA!! They answered right away and these angels over here said they would sent someone out SAME DAY! This is a busy time for AC techs so it did take a few hours this time to come out but I was still happy they could come same day. While we were waiting, the pipes outside unfroze and I started my AC back up to see what would happen. It was working! When Sierra called and text to let me know PAUL was on his way, I still decided to have them come out because nobody wants to wake up I'm the middle of the night and have no AC again. Come to find out it was mostly our own fault. The filters were dirty and wasn't providing enough air flow so it was over working and froze the pipes. Still worth the $89 service fee for a peace of mind. He did suggest a couple maintained and parts that may go out at some point so might end up doing that next. Will continue to call SIERRA for our AC needs.

Our company was using another service and they would come out & never get anything resolved. They would say they are returning and never come back yet they would bill us for hours and hours of work with no result.

I chose to call Sierra LLC Air Conditioning & Heating and they came out the same day and fixed the issue right on the spot. Their customer service person, Jen S., and their Serviceman, Frank, took amazing care of us and got our AC issues resolved. From that point on we ONLY use Sierra LLC Air Conditioning & Heating!

They've come out a couple of times since then and always give us same day service and resolve the issue immediately.

I would HIGHLY recommend Sierra LLC Air Conditioning & Heating to anyone needing their units serviced!!!

They told me they would go out and give my rental property an energy auditand email me an estimate for a new unit. The existing AC unit died and I was getting multiple estimates.

The energy audit consisted of the technician coming out and asking the sq ft of house, calculating 400sq ft per ton and then bumping up the unit a half ton in size. That is not how you calculate how big a unit you need. Google AIR CONDITIONING SQUARE FOOTAGE RANGE BY CLIMATE ZONE. Most AC companies will oversell on size of unit needed. His calculation will definitely oversize the unit needed. Then we get the estimate. Only thing it says is basically size of unit and the price of job. No model number of unit, no price of unit and no breakdown of labor cost. I was told by rep this is the industry standard estimate?

Our company has been in property managment and real estate investment for over 10 years. We've had to replace and repair many units over the years. Yes. It's the standard if you are hosing your customers. Their estimate was over 50% higher than our other 2 estimate.

Got scammed of $85 and if not from the other reviews here could potentially be more! The guy this company send told us after few minutes of walking around that there's a leak in freon which I suspect is not the problem. We didn't agree on the repair so the guy left. We decided to call a different company with the best reviews the next day, lo and behold the problem is just electrical and the line is completely toast! How could the first guy miss the basics and already decided to go on a more expensive one? Thanks to the honest reviews on yelp that help us saved money. Here's the picture of the real problem in our a/c system-

When Pulte built my home they selected Sierra, who installed a York A/C unit that failed due to tube joint fracture after just 3.5 yrs. The unit is under a 10 year warranty (parts, not labor) from York, which the nighttime tech and his call-in manager (worryingly) did not acknowledge, but that the day manager corrected the next morning (without my prompting or arguing about it--he called me to correct this). Since this York A/C condenser manufacturing series had some known issues discussed in on-line forums, Sierra quoted a fair, low, price for labor and a completely new condenser & refrigerant, to eliminate all doubts about keeping the failed one as a repair job. As I would have been on the hook either way for the labor, the difference in cost I paid to obtain an all new piece of equipment I think is very fair and reasonable. They did a detailed quality job of cleaning, vacuum drying and testing the refrigerant loop and installing a new in-line filter. They showed up on the days promised and did quality work without rushing through it, answering all my tech questions (I'm an engineer). We confirmed the system is supplying the expected amount of cooling for the measured amount of power it is consuming. I don't have enough data and experience to say that York is a brand I'd recommend--time will tell--but as for Sierra's contracting, they did a good job in both the actual work and in communicating the details of the issues. The three techs I worked with arrived clean, behaved professionally, communicated intelligently, were well trained, and drive a clean well organized truck.

Sierra did the install on our last new-build home, this new one unfortunately had a lesser subcontractor do the install. Sierra has come out and fixed all the problems the original installer left. They even figured out some clever work around to make the system significantly more efficient for a pretty cheap fix cost. Huge shout out to Alain who is incredibly knowledgeable, honest and professional, really knows his stuff. Everyone who has come over the years have been great as well!

Do not use this company, I have a toll house that was built 2 years ago, I still don't have a proper air flow my girls room is either super hot or cold bc they never fixed the duct work. They must of come out 5-10 times and never fixed the problem. Till Brother never should of hired them in them for luxury homes. This company doesn't care.

They came out to fix our unit but when they had to put back our ceiling back together it was put back I. Patches and nails sticking out of the ceiling and said they would be back to repair it it's been 3 weeks and no one called to repair the ceiling's when they installed my new system they did not insert some kind of liquid to cook the house down so the sautés souls freeze and my house was hot for at lease couple days before they could come out and fix the problem again

I moved into a new build right before covid started and my heater has never consistently worked but due to covid I didn't get service I purchased a small plug in heater. I finally had Sierra Air come out to fix the issue since they are the company that installed my unit. The rep they sent spent a few hours running test and told me there's nothing wrong and changed the thermostat as the last result because he said that has to be the issue, the next day my heat was malfunctioning again so I called Sierra again and they sent a new rep Micheal Johnson to assist and he was extremely efficient in figuring out the issue so after several hours he had my heat up and running and as of now (7days later) my heat is working great finally. Thank you Micheal Johnson for your expertise, friendly demeanor, and time.

I would definitely recommend Sierra. I have two units both installed in 2013. I am signed up with their maintenance plan to have service twice a year. During COVID both tech Francisco and Miquel arrived on time, wore masks and shoe booties. They checked all electrical components
and connections. They tested the motors and checked for bearing wear. Assessed system refrigerant charge and overall performance. Cleaned outdoor condenser coil, checked indoor coil, and drain pan. Installed pan treatment. Checked blower wheel for cleanliness and proper balancing. Replaced air filters. Check the amp draw on all components. The only thing I noticed is that my invoice said they inspected my ducts which they didn't because I don't have a crawl space and they didn't look at the ducts inside. I called the office to notify them and they are suppose to call me back. Thank you!

I called Sierra Air at 7:12 PM to report that my upstairs unit was not cooling. I fully expected them to put me on the service list for the following day and was dreading trying to sleep in a 90° bedroom that night. Much to my surprise and delight, the gal on the phone asked if I would like a technician to come out that night. I told her YES please and she cautioned she didn't know what time he could get there. At 7:50 PM I received a call that the technician was on his way and he arrived within 15 minutes. Let me just say that Darryl O. saved the day! He was professional, clean, friendly, knowledgeable and got our air working by 10:00 PM so we could have a comfortable night's sleep. I highly recommend Sierra Air and Darryl.

We continue to have extremely positive experiences with Sierra AC and Heating. Our AC went out over the weekend and when I called Sierra on Monday morning they immediately scheduled a technician to come out the same day. Fabian Pantoja was the tech that came. He quickly assessed the problem and gave us several options for repair. Fabian did not leave until he resolved our situation. He was professional, incredibly knowledgeable and courteous. Lastly, Fabian was honest about what we could expect in the future. My husband and I only trust Sierra AC to handle our AC needs.

I have been paying for their service, $25 month, I scheduled a maintenance service on May 30th, 2023. I was told they were so busy that it would not be until July 28th, 2023. So today they send me a text stating they are too busy to come out. That is NOT how you do business. My schedule was adjusted to accommodate this scheduling. Why pay for a service and not be a priority? Sierra Air Conditioning and Plumbing is a huge let down and made me feel totally underappreciated.

Technician - 5 stars

Products/Solutions - 5 stars

Customer Service - 5 Stars

Called on a Wednesday morning about 8am after noticing that our air conditioner wasn't working.. the customer service team at Sierra Air made an appointment window for later in the day. They called about 20 minutes before arriving and had the problem diagnosed, remedied and the system up and working within 30 minutes..

As a family of six with many daily activities it was refreshing to know that they didn't waste our time. They showed up, in professional attire and got the job done.

A+ outfit, I'll be referring others to them!

Beware! If I could give negative stars, I would! Sierra Air will OVERCHARGE and UPSALE and PRESSURE you to replace an entire system at a premium price tag! We were charged $500 (approx $400 for the part and $100 for the labor....that was after a $50 coupon was applied). The tech also told us that our system was going to fail completely and tried to get us to agree to speak to a sales rep to replace the entire AC system at a cost of approximately $18,000+. He showed us LOTS of pictures of multiple parts and told us those parts were failing or going to fail. We declined to speak with a sales rep.
After we did our own research and got multiple other opinions from several different companies, we found out that the $400 replacement part SIERRA AC charged us for actually costs around $79! AND some of the other companies said they wouldn't even charge us for the part because it is a common part that goes out often. Additionally, the other companies said that there is NO REASON to replace our entire AC system. When we asked about all the other failing parts, the other companies physically showed us those parts and said that it was just normal wear and tear with some dust/dirt accumulation....nothing extraordinary. Additionally, these other companies told us our system should last another 1-2 years. We asked these other companies what the approximate price would be to replace the entire system if/when it ever fails. Uniformly, these companies quoted us between $9,000-$10,000. Think twice and do diligent research before hiring this company. The tech that came to our house was very skilled in using scare tactics about how decrepit our system is and high pressure sales to get us to agree to replace our entire system. Buyer beware!

Very pleased with Sierra Air. I had an appointment window of 8 - 12 and really appreciated that someone from the office called to let me know a more specific arrival time on the day of service. The technician Eric Otero was wonderful. He took his time to go over all the details of the service with me and also offered suggestions that I may want to consider going forward. He was very professional and thorough and a definite asset to your company.

I was such a pain due to my AC not working I called Sierra mind you it was around 10pm cause I couldn't sleep my poor babies my AC stopped working.. so I went to work and my poor babies stayed home I was told they would be at my house at 12 but I guess I misunderstood them, they said after 12, so if they say after a time frame don't worry they will come and they will deliver awesome customer service. Tell you upfront prices and give you options I felt at ease and again I do apologize for being a pain I am not use to this heat and I was just being impatient, to anyone having issues with your AC I HIGHLY recommend this company thank you guys for an awesome service thank you Jesus I feel like heaven in my house now!!

Posting for my parents, who don't have a Yelp account but wanted to give their input:

The motor on our heater broke, and as we found out that night, the desert chill is not friendly on old bones! We called Sierra AC and Heating, and Zachary Ruiz came to assess the fix the problem. He provided outstanding service - knowledgeable, quick, and very respectful. We were impressed with his work, really a job well done. We hope we won't have any heating/AC problems anytime soon, but we'll know who to call if we do.

I called Sierra due to the fact that one of my home heating systems failed. I was given an appointment the same day I called. Then to my amazement, Sierra called back and said they had an opening earlier if I would like the technician to appear sooner. Of course I took the earlier appointment. They identified the technician that would be servicing my equipment as WAYNE. Wayne showed up even earlier than the time quoted to me by the office person. Wayne was a very professional and personable technician. He diagnosed the problem, repaired it, and then checked the entire system to make sure all was in proper working order. Wayne explained the problem in layman's terms and fielded all questions I had about the problem and system. He was very knowledgeable and went above and beyond to insure my system was completely repaired. Wayne left the job area in pristine condition and also cleaned the components and enclosures of the system. His work ethic and abilities are exemplary as witnessed by his performance. Wayne is the second technician that I have had the occasion to utilize from Sierra and I would highly recommend him and Sierra to anyone requiring HVAC work. You won't be disappointed !!

This company wanted me to pay over $900 to install four vent registers...... So I would guess the labor would be $850 to remove 8 screws and install the four registers that cost $50!!

I had also purchased a annual maintenance agreement for $190 for the year. When my tenant called to say they were having an issue with the AC I called Sierra to have them perform the Summer check. They still wanted to charge me $69 for a service call. When I asked why do I need to pay for a service call when they were already compensated for the maintenance package? The said that they have to charge for a service call to determine the problem. I asked for have of the maintenance packaged to be refunded and applied to the service call.

I should have ran with my refund. Now the tech says that there is a leak at the condenser? Read the reviews.....I bet it will be $1000's. I will follow up. But everyone should stay away from this company. By the way, I am still waiting for the owner to call me back.

The outrageous quote and this company drove me to my first review on Yelp! So thank you for that Sierra! Now I will have to make some Friends...........
It is very strange to see such extreme differences of bad and good reviews. It makes no sense....unless something is fishy?

Follow up... $9000 for a new system as my system is too old. But I would get a 12% discount to net at $8000! My system is old, however doing some research I found that I could buy a complete brand name 2.5 ton seer 14 system for $1400-$1500. This is retail! I am sure Sierra gets parts for much less. Labor and other parts/fabrication of the air handler couldn't be much more than a $1000. Sierra has a job posting on Craig's list for HVAC techs up $30 per hour. So they are making a $5500-$6000 company dollar on my estimate?

I have 3 bids so far from a few of the highly rated companies in Las Vegas. The estimates are from $4400 to $6000. These bids seem much more in line with the cost calculations I have mentioned.

I will say that the Sierra manager did reached out to me. He was extremely professional and listened attentively. That has to be worth an extra $2000-$3600 right?

RJM (Rocky) if you read the review and talked to Jack, the exorbitant pricing was just a part of the problem. But with that said, thank you for the poor response.

Update1 : 7/20/2016 Black Mountain serviced my unit over a year ago for $200 and it is still working. Thank you Black Mountain!

Update2: 7/6/2017 It has been 2 years since my service by Black Mountain. Unit is still cooling.

I have an ongoing issue with Sierra dating back since the purchase of my new home. When it was in warranty and beyond regarding a/c and heat. I just had a tune-up in March 2021 regarding heat circulation. Each time the technicians come out they say everything is fine when it's not.

Zach, the manager was kind and offered an evaluation upon my request behind another technician work. Which I mentioned in my last review. The a/c units were cleaned and a diagnostic was done. Again, I was told that everything was fine and that the motor blower was a little dusty.

I asked if I needed duct cleaning and was told no. Zach said to keep in contact to see if the issue would get better since this has been an ongoing since the beginning issue for awhile. The problem was temporarily fixed but now I'm having the same issue with air flow and circulation throughout the home.

I did research and am wondering if the air ducts are the right size for the home instead of the a/c units. Sierra stated that the units are correct according to guidelines for the home square footage. My neighbors are also having the same issues and not just me. So, something went wrong down the line in construction of these new homes. And I would like to know what it is? I'm not receiving a straight answer neither from Sierra of the homebuilder.

I called last Friday, 8/6/21, for someone to come out. And they want me to pay $89 for a visit. I don't think so, for what? Just to tell me everything is fine, when it's not!

Either there's a leak or blockage of some kind when the air ducts were installed. Or something is wrong with the motor blower? I was told that a/c units run off of freon to keep the home cool and maybe low. With all of my dealings with Sierra, they have never mentioned freon before.

I've been looking into having my ducts cleaned. There's benefits such as over time, fine dust, dirt, dander and allergens build up inside your HVAC system. When your A/C or furnace comes on, you and your loved ones, are breathing this unseen dust. Cleaning your system will produce clean healthy air inside your home or commercial building. Besides breathing cleaner air, you will also save energy and have your AC system and furnace last longer with fewer breakdowns. Finally, reducing dirt and dust will help keep your home or building cleaner.

Both technicians in March of this year who visited my home said otherwise. And that it wasn't necessary although they saw that the motor blower was dusty. I guess Sierra main goal is for us not to use air duct cleaning services. because they will not be able to profit from a service that they do not provide. And dirty air vents will lead to the a/c and furnace units to breakdown. Causing the homeowner to purchase new ones which keeps Sierra in business.

Thanks, Sierra for your honesty and not sharing the benefits of having my ducts cleaned. You told me that the blower was slightly dusty and air duct cleaning wasn't necessary. But I'm constantly coughing and sneezing due to unseen dust being blown into the air that I breathe.

During the meantime Zach hasn't returned my phone calls regarding the matter. Eventhough, he asked me to follow-up with him if I continue to have issues.

Sierra is such a reputable company. Keep up the good work guys! Have a rest of your day!

Sierra Air conditioning told me my air conditioner was under warranty so they would charge me only for the labor and they would have to send a technician to do a diagnosis ($75). The techinician came out and did a two minute check and said the compressor was shot (I told him it was the compressor). Then called and was told my ac wasn't under warranty. I argued only to be upset to pay $75 for a technician do two min of work. HE ALSO HAD THE ODACITY TO ASK ME FOR TIP MONEY. WOW YOU MUST BE JOKING! NEVER AGAIN.

So my heat went down on a 1 year old house. Talked to builder and they said I would have to go thur manufacturer and they use a company Sierra that installed it. So I called and they came out 4 hours later
Which is already amazing. Dan showed up very professional and walked me thru what he was doing. He found the problem and took care of the issue. He filled me in on company promotions and other tips but in a non pushing informative way. All in all great service all around 10/10 recommend. Dan is awesome

If I could give no starts I would. Up until this experience I have always used Sierra LLC. They initially installed my HVAC in the house when it was built. When we lived in the residence we had them out a couple times and were pleased. Not sure what changed, but our AC went out on our tenants, so we called Sierra as we had in the past. They came out a day later, charged $69 for them to even look at the system. After they trouble shot for a while I get a call telling me the estimate is $1100 to replace a control panel. This seems pretty high so I ask them to not do the repair. Boy am I glad. The next company, Legacy Air, came out and it was actually the blower motor. There were also other issued with the HVAC from previous repairs, all done by Sierra. Legacy fixed everything for under $540! Never using Sierra again! Scammers!

I have been doing business with Sierra for years and their service gets better and better. Ruben assisted me with a reverse osmosis system and he was confident it would give me the results I wanted in our drinking water. I already own the HALO 5 filtration system and Ruben explained to me in detail how the RO and HALO work to improve our home's water. Sure enough, our ice is as clear as I have ever seen. Our water taste so crisp now. Thank you Ruben!

This was my first experience with Sierra doing a wellness check on my system. The technician Justin Carlyle was great! He answered all of my questions and explained everything in great detail, to where I could understand what was going with my system. He also gave me some ideas of how I could get my system running more efficiently which I appreciated very much.

I joined their monthly membership program and will be using them going forward to maintain both my cooling and heating systems.

Sierra air put in the air conditioners (2 units) in our new home in Buffalo Ranch which are now barely 2 years old. So when we got a flyer on our door offering a $59 servicing for our air conditioners I decided to call them to schedule an appointment. They had come out previously in Feb.and changed them for around $80 (it took him longer to take his ladder of his truck than it took to change them, probably 15 minutes) so I thought this would be a good deal. The customer person asked for my address, and then put me on hold. I had explained to her we did not need a service, only the filters changed and I was providing the filters! My husband worked on big Hotel chillers and air conditioners for years in Waikiki, so he keeps our condenser and evaporator coils clean as needed and takes care of our systems (which by the way he says the installation they did is a joke, we had to put shims and level the units ourselves because he put a level on them and found the were not level!) Once a year he polishes them to protect them with auto polish and they look brand new! But he is now disabled and unable to climb a ladder and I cannot climb a ladder to do the filters.

When the customer person came back on the line she said her boss said since we had two units, that the price would be twice what the flyer offered, even though we only needed someone to go up the ladder, change the filters we would provide and come back down! I guess when you get to be the biggest in the Valley and have so much overhead you have to take advantage of people. I reiterated to her, we only needed the four filters switched out, and they are located in the same panel door. She said double the amount! After reading these reviews I realize they probably knew they couldn't charge us services they might have found when doing the whole system since we told them we didn't need it.

Just so you know, many of the new units come pre-charged with gas from the factory. They should also have a tag on them telling you how much is charged either in lbs. or ozs. When they tell you they put so much in, check the tag to see if what they are telling you is the truth.

My husband has a new saying after seeing all the contractors in this town who are not ethical, Las Vegas is a very sunny town, with very shady people!

I called Costco program and they sent out Shawn Brown to give me a quote on getting a new HVAC system. He seemed like he was not interested in the job I wanted. He told me he needed to come back to my house again to talk to me about creating a new system with different specs. I asked him to email me, he said ok. I waited 13 days, nothing, so I purchased a complete HVAC frump another company and am extremely happy with the other company!

My water heater sprung a huge leak the day after Christmas. I asked around for recommendations and my folks had suggested Sierra since they had used them for their HVAC, so I called them. Ruben came out for an initial inspection and estimate the same day. And even during the holiday season, got it completely replaced and working 2 days later. The cost was a little more than I expected, but I did get hot water back very quickly. I appreciate Ruben and the work he did for us.

This company has the most professional technicians I have ever interacted with. They listen to your concerns and don't waste anytime getting down to business. I had the fortune today of having Fabian and Christopher come into my home and assess the problem with system. They completed a thorough diagnostics of the ac unit and the resulting diagnosis was spot on. They were went over the situation in terms I could understand enabling me to make an informed decision. Truly 5 stars is not high enough of a rating these two professionals far exceed 5 stars.

I have been a customer for the last 7 years and have always had a positive experience with Sierra. Their customer service and their technicians are always courteous and knowledgeable. Just had my summer tune up today performed by Derek S. and as usual I am totally satisfied. Also a thank you to the customer service rep that kept me updated as to my appointment time.

Cameron S.

My fan motor started malfunctioning Friday evening prompting me to call Sierra who was able to schedule an appointment for next day!

One of my biggest pet peeves for scheduling appointments is the large window of time they give you and show up with no warning. Sierra proactively mentioned they call 45 min in advance so I could run errands and go on with my life.

Overall I was impressed with how well they communicated and even followed up after servicing to make sure I was satisfied. They have most definitely won my business for the future!

It's also important to mention my part was ordered and installed in a quick and professional manner!

WOW!!! I am just so impressed with Sierra Air Conditioning. One of my 24 year old HVAC units went down on July 3rd. I immediately started seeking out reputable companies on the Web, but who knows which reviews you really can believe. Were the positive ones written by friends of the company, while the negative ones by competitors? So I asked my neighbors and Sierra's name came up twice.

I contacted them on July 3rd and they were out here on July 5th to assess the situation. They even offered to come out on July 4th at no extra charge.
I first met with Willie (their Sr. Tech) and after going up on the roof in 100+ degree temperature, I decided it was time to terminate the unit. Even though a repair would have been less expensive than a replacement, who knew what else would break...and 24 years is a good run for an HVAC unit.

I then met with Jared (Comfort Advisor) the same day, to pick the most appropriate unit. This was not a tag team pressure sales situation...just the opposite. They let me know which units would be overkill for my home, especially since I have two HVAC units. Willie and Jared were extremely professional, friendly, knowledgeable, agreeable, patient, funny, good listeners and down to earth. I chose the unit and the work was scheduled for the next day.

Adrian and Omar (techs) arrived around 9:30am the next day. Both gentleman were extremely personable and knew their craft. They spent hours on my roof where the temperature had to have been 110 degrees. By 3:00pm, the crane had taken away the old unit and replaced it with the new one. Adrian and Omar completed the HVAC installation and also replaced two old thermostats in my homes. The cool air is blowing as it should and my upstairs is now livable again.

Although I have a maintenance agreement (aside from the unit warranty) it's good to know that Sierra is there 24/7 with no extra charge for weekends, holidays or evenings.

With so many untrustworthy, irresponsible, deceitful, unknowledgeable and dishonest contractors here in Vegas, it's nice to find one that you can depend on.
Sierra Air Conditioning and Plumbing should be your first call for all A/C needs.

So two days ago we had our air stop working. The unit is only 7 years old. My wife called Sierra Air and got the run around, they told her it was out warranty after five years but Todd came out right away, check it out, contacted York and found out we had 10 years, I called Sierra back and still got the run around so even after they admitted it was covered, we decided to pay the extra $400 to go worth Black Mountain. If I don't feel I can trust you I will not give you my business. Labor and other parts would have cost us $1000, so we chose to go with Todd. I still had to pay the $1000 plus $500 for the parts but I can trust Black Mountain.

Both times I requested to make an appointment they were available to come out same-day, which I was very grateful for given the 105°+ heat and a dysfunctional A/C. I will mention that it was quite difficult for me to get ahold of someone in the office (no answer at times w a full voicemail so couldn't leave a message). I made my first appointment online and it was very easy. My second appointment, I called in. Ultimately, the gentleman who came out and fixed my A/C was able to pinpoint exactly what the issue was & their invoice to me via email was extremely detailed and thorough (photos and all). They were able to honor my parts warranty (I bought a newer home a few years ago), but the labor of course is what gets you ($$$). Luckily the issue was just over $200 and took maybe an hour to diagnose & fix (he had the part needed in his truck). My A/C has been running perfectly ever since!

Daniel Alcala focused on what was needed, and what could be invested in moving forward. He is a professional and stated that some things were not to his standard...I like that because my problem became his problem. He represents the brand well and took every possible precaution given COVID restrictions.

Sierra Air Conditioning and Heating is the ONLY company I use on my home and rental properties. I have them out 2 times a year. I have even replaced 2 units in my rental property. Easy to make appointments, techs call when they are on their way. Techs always explain what's being done. When inspection is complete they tell me what was done and what might be needed. Techs are clean and respectful and always clean up.

From the initial call from Dabari, the earlier appt available call from Susan and then our technician showing up, it was all a very good experience. Now our appt was the return cover falling off and we have a new build, so we didn't have some crazy crisis or expensive situation, but the professionalism was there.

Our technician Johnathan Escobedo was fantastic. Very professional , respectful, and prompt. Also, what really made him stand out was the time and attention he took to explain items to my wife and I. Instead of simply sounding like he was selling us something , he took the time to truly consult and advise us on our options. Because of Johnathan, we will continue to do business with Sierra.

I totalllllly recommend these guys... IF you want to be scammed!!! Long story short, I called these guys because there was a sticker on my AC unit with their information on it. You see, my AC unit stopped working and it was a 109ﾟ out. When I called I simply asked if my unit was still under warranty. The man on the phone assured me over and over again that it was (for parts, not labor). He said they were the ones who did the install originally so he would definitely know. I asked him specifically do you need the model number or serial number to which he replied no not at all. They sent a technician out later that day. He inspected my unit and made a few calls. Shocker! They made a big mistake! The unit is not under warranty after all!

Listen, I am a single mom and have no time (or money) for scam artists. Also, I am from NY & happen to have street smarts. I told the technician that I did not appreciate being scammed and asked the technician to leave immediately. He asked me to give him a another chance and went outside to make more calls. He came back in and offered me the work at a much lower price than originally quoted. At this point I don't trust these guys as far as I can throw them so kindly declined.

If you are looking for an honest company I highly advise you to continue your search. I ended up going with another company who provided honest, top-notch service. The company I ended up using thoroughly explained to me my options of either just replacing the compressor versus replacing the entire unit. I ended up replacing my AC unit for a very reasonable fee (and 10 year warranty). If you would like information for the company that I ended up using please send me a pm.

Sierra Air, in my opinion, takes advantage of their customers. If you are a single woman be especially careful! Shame on you Sierra Air! Would you treat your mother like this, your sister? Doubtful.

After calling Sierra Air Conditioning at 8:30 at night, a technician showed up at 11:30. He was nice but didn't seem to know too much about the trade. After blowing my breakers twice and messing with my furnace for 2 hours, Greg realized my air condition was actually out side. He thought that is was a spit system but it was actually a package unit. He spent another 2 hours messing with my air conditioner before informing me that he was leaving and they would send another technician out in the morning to fix it. He told me to wait for a phone call from the office. After sleeping in the heat with my 10 year old, I called the office only for them to hang up on me. I ended up fixing the problem myself, bad thermostat, but still haven't heard from Sierra Air Conditioning until 2 days later they called to try and send a technician out. No thank you, I will never call you guys again.

Tyrone came to our rescue! He came into our home kind & friendly prepared with his mask and booties during this rough COVID time! He was able to get the job done in a timely matter & knew what he was talking about. He explained what the problem was & what he did to fix it. He also answered additional questions we had. I Highly would recommend Tyrone if you are in need of An A.C emergency.

Excellent service. I used this company for 3rd time now on different properties. This time Zach was my tech. They give you a book with pricing and common failures. While Zach was on the attic checking my furnace I had plenty of time to go thru the book and also read recommendation. While wondering what is going to sell me I was surprised that the actual problem was the cheapest item on the book. He said this is to make it work. There are other items should be addressed and showed me pictures on the phone and explained step by stem how much and why it should be done. I told him house is for sale and only want to repair it not invest in long term items. He wasn't trying to push or sell anything just gave me my options. I loved it because that's exactly what I do at my business.

We purchased two new HVACs December 2019. Since have had two PMs done under the warranty feature. Always a pleasant experience and I appreciate the professional yet friendly service people. Phone staff are warm and pleasant.
The quality of work was great and they cleaned up any mess during the install. Our house has been comfortable each season.
We plan to continue to Sierra's maintenance program for future PMs.
Most definitely feel comfortable with Sierra and we do confidently recommend Sierra!

I have used Sierra Air for my twice-yearly maintenance (Spring/Summer and Fall/Winter) of the HVAC/furnace since I moved into my home in 2016 and will continue to use them for their consistent and thorough service. They are good about confirming appointments and keeping customers informed about where the service tech is and estimated arrival time for each scheduled appointment. I signed up for their maintenance plan, which provides more discounts and also ensures that your AC, furnace, and any other items they help service and maintain are being checked every year and in good order.

Tracy D. was my service tech this week, and he did an excellent job on letting me know of the furnace performance and filter condition before any work was completed. And he didn't rush through his inspection or the work he did replacing anything, which is always appreciated. I've seen some of the other Yelp reviews on Sierra Air where people say that they charged them for work not needed, and I haven't had that problem in the 4 years that I've used them. Tracy and all of the service techs have been very honest and hardworking, so I will stick with them.

We have been using Sierra Air for almost two years after working with several unreliable and unethical air conditioning contractors companies. Sierra Air has been established for years and came highly recommended by a friend who is also in the contracting business.
They are very professional-and actually come on time and very kind.
We purchased a maintenance contract with them and pay a reasonable monthly fee which includes 2 service appointments per year-one in summer to check the air conditioning units and the other for the furnaces in winter.
Our units are running perfectly. The tech we have recently seen is Daniel. He is so personable and knowledgeable.
Sierra Air also takes pictures and video of the Shyam that the homeowner can have visual support for the recommendations -they are also emailed to you for your records.
We had air filtration systems installed on our two units most recently and we are excited about not having to change our air filters monthly-now only once a year and Sierra will do the changing for us in the attic when they service us for no additional fee if we provide the filters. Looking forward to cleaner air and less mainly.
We highly recommend Sierra for their professionalism and long standing reputation!!!

If you need a fast and professional company. Call Sierra Air. I am new in town and wasn't sure who to call when my air went out. From the beginning with talking to customer service to the end with the tech. They all were friendly and professional. I received same day service. They called me 30 minutes before to let me know the tech was on his way. When the tech arrived he put shoe covers on before entering my home. He explained to me in detail what services he was performing. He was very courteous and thorough. I will call them everytime. And I will refer them to everyone! Thank you Sierra Air!

Highly Recommend

This is the second year we have had them do our annual tune-up for our a/c. In spite of the fact that we have a home warranty who we would call for any repairs, both technicians -- who obviously know their business well (this year it was Jeremy -- I don't remember the name of the guy last year...) went out of their way and took the time to explain all issues and answer all questions. If we are ever in a position that our home warranty does not cover repair or replacement of our unit, I will not hesitate to call Sierra...

During this past summer, when my air conditioning unit would shut off it would make a noise that sounded like metal on metal. It didn't sound good. I continued to use the a/c for the rest of the summer and told myself that I will get it taken care of before the winter. That time came to call them. I called them Wednesday (10/30) and the woman that I talked to said that a technician would come out between the hours of 4-8pm. When 7:30pm came around, it didn't seem like a technician was going to come so I called back to reschedule for Friday (11/1). I received a text a day before my scheduled appointment to remind me that they were coming. Friday came and a technician by the name of Joe came out to inspect the unit. He pretty much told me the compressor was bad and leaking. He also said that this unit would break down next year due to the age of the unit being over 10 years old. To be proactive, I decided that I should replace the whole unit. Joe helped me set up an appointment with one of their comfort advisor to come out and give me a quote on a new unit. Yesterday (11/2), Rob Dais came out to quote how much everything would cost to install a new unit. He also took pictures that were needed. I asked if they provided financing services because no one has money like that to pay for a whole new unit. I also asked if they do military discount and they said they do which helped me save more money. Rob made the process with the finance department and what he had to do as a comfort advisor very smooth. I will be getting a new unit replaced next Saturday. Even though I have payments to make for this brand new unit, I will have a working a/c and heater. Thank you for being professional and helpful. I will be doing another review once the job has been completed.

12/26/19- Been waiting til this day to do a review because the project wasn't done yet. A few weeks back two technicians from Sierra came to install my new system. Jose and Azuel (don't remember how to spell his name, Sorry!! ) came in and went straight to work. They did an amazing job. Today (12/26/19) I had my inspection with the city. Vincente from Sierra came before the inspector. When the inspector came, Vincente was here to assist him and if there were things that needed to be fixed Vincente was there to fix it. I passed the inspection!! I'm so happy how everything turned out. Thank you Sierra for doing such an amazing job from beginning to end. Your technicians are amazing and knowledgeable.

I've been diagnosed by 2 other companies as needing to have my system balanced. Stephanie at their place tells me sure we can do that ...no problem. So I tell her to get me the first appointment even if i have to wait 2 weeks (instead of we'll see you 12-4:00 pm.) Last night I get a call to confirm they'll be at my house at 9:00am. (OK, if this is first thing.) Of course I see a missed call at 7:00 am. When I call Miranda tells me...Oh yeah, you didn't answer so he went on to his next appointment. But you'll be next whenever he's done...and what do you mean by air balancing? ...we have to charge you JUST to come out to diagnose...(Keep in mind I ALREADY TOLD them the diagnosis..I need the cure!)

Problem is it's July in Vegas. Maybe I should get into the HVAC business...I can go out an tell people..Your system not working...that'll be $59! Wow...nothing like Professionals!

Called Sierra for a second opinion. Ulisis showed up and was extremely helpful and informative. Spent the time to explain what the reading meant and to show that my systems were NOT in need of expensive repairs/replacements recommended by another company.

Thank you Ulisis! You saved me several thousand dollars. You also got a new customer for Sierra.

I have always had great experiences with Sierra. They are very professional and always customer service driven. This time, Drew came out to maintenance the units before summer. He was very knowledgable and was able to articulate his review very easily and in terms I can understand. He didn't try to oversell me on things and was completely honest.

Tyrone from Sierra Air Came to do the servicing of my air conditioner and water heater. Tyrone had been the same person who came out for the summer service.
I felt very comfortable and knowing Tyrone would answer any questions or concerns I had I felt safe.
Being a woman homeowner , even after 13 years of handling issues , it is nice when a company employee
treats the customer as if directing parents or siblings.

Thank you Tyrone for making sure my vents were open to evenly distribute the heat. I also am so glad you helped me understand the setting either had to be cool or heat
I have been with Sierra since 2005 and people like Tyrone and the entire customer service staff are what keep me with them. After being in customer service 33 years I appreciate when I get customer service. People who take ownership and actually follow up are too few and far between.

I'm retired HVAC, permits hindered my ability to install a AC system.
Sierra Air is the Best Price and Guarantee that I've found. They Used my existing Thermostat wire (TW), gave me a Senior Discount among others that I qualified for.
All of the 4 other companies (the one's that you see on TV) didn't offer me a Single Discount.....
The Other companies;
1 wanted to rip out my Return Duct (RA) and install a bigger size Ducting. He created more work for (more money)
Now Remember that I'm retired HVAC.
Another wanted to install a pump for a Natural Condensation drip line (more money)
Another asked me if I wanted the Quieter condenser? But for (more money)
I've worked with the Carrier brand throughout my career and they've Always been the Best.
Sierra Air even Sealed the existing Duct connections beneath my house because they knew that I had a pressure test due after their installation. (Douglas County code)
The 4 out of 5 estimates that I've received, they all oversized the AC Condenser(a bigger size is More Money)
Except for Sierra Air. And if it doesn't Cool my house down enough, Sierra Air will install a bigger AC Condenser for FREE.
From the start Sierra Air had the Best Price and Guarantee!
Thanks to Will O'Keefe, Ethan, Johnathon and Leanna at Sierra Air!

We use Sierra for our air conditioning and heating needs. They are the ones who installed our A/C and Heating when we bought the new home. We are on a monthly payment program which covers both.
Yesterday, our A/C went out for 1/2 the house. We called Sierra and they were able to come out the next day (today) I was greeted by employee Ulises Hernandez. He was friendly, polite, and very responsive. He found our capacitor went out and he replaced it. He also checked the entire unit and found it to be running smooth. I would highly recommend Sierra, and especially employee Ulises to service your home.

I bought a pulte home in 2016. I was 1st having problems because either pulte or Sierra put the vent in the master bedroom about a foot to the wall where the entrance of the bedroom was and it took them about a year to finally move it. The technician, Jonathan (looks like the kid in one of the reviews) was so condescending because he kept having to come back for things that Sierra did wrong. They finally sent a tech out that figured out why the neighbors a.c. was making a really bad audible noise when they turned the a.c. on. You could hear the noise throughout my house and would keep us up at night. Jonathan would always say he didn't hear it, but the other guy did. I don't remember his name, but he was a manager in another department. Crazy thing is when I told the owner what a great job he did finding the problem, the owner talked bad about him. Anyways, fast forward to today. I had told Jonathan about rattling every time we turned our air conditioner on, and he said it's just something that happens, and he can't fix it. Over the years, it had gotten louder and louder to the point I couldn't sleep. I got up in the attic, held the unit, and listened. It was still rattling. Come to find out the bracket on the hardest side to get to on the unit was not bolted down. I had to snake my way through the attic, take a string, and tie a knot around the bottom bracket and the long screw looking thing to get it to stop. The a.c. is so quiet now. I hope that the string lasts for awhile because it was hell getting through there. Sierra, please don't write back to me with any b.s. p.r. stunt. The only thing I want to hear is that you're coming to bolt my a.c. unit down, and I can update my review.

I have Sierra on an annual AC/Heating contract. All of their technicians are well trained in terms of customer service. Today I had Derrick come to my house to perform my system check-up. He was very courteous, thorough in his explanations, and patient with my questions. Sometimes when companies get very large the employees lose the personal touch. Thankfully, this hasn't happened with Sierra.

The initial call to set up the maintenance appointment was very expeditious.
Keith had arrived on time and was most helpful and very professional.
Keith was scheduled for the heater maintenance, however, I had expressed my concern about a rather loud A/C compressor. He viewed the situation and discovered a noisy motor bearing. He replace the motor with a new fan blade and most of the noise dissipated. He then ordered a different blade of which was installed two days latter and totally remedied the situation.
In this day and age many people don't take the time to completely satisfy their customers. Keith in fact went beyond the norm to satisfy this customer.
I appreciate this type of service............

Have utilized Sierra at two different homes here in Las Vegas since 1992. They have yet to disappoint me. Their technicians are always on time as well as professional & friendly. I had Summer Service accomplished today. Two Technicians performed it, Jose & Ricardo. They did a thorough job, changed out my Lennox PCO Filter & UV Light, and assured me the system was functioning well. Continued Kudos to Sierra LLC for superb service!

I have had Sierra come out and maintain my system since I purchased it 5 years ago. They are always great, but today, Andres Valdez went above and beyond. He took pictures and videos of everything he did. I mean everything. He showed them all to me when he was done. I felt like I myself was in the attic doing the work. His attention to detail and customer service was amazing. Well done. I'm recommending him to come and service my system every time.

I'm so grateful for Sierra Air and Wayne E!!! We purchased a 22 year old home and knew the A/C was old so I wasn't surprised when our house wouldn't cool down this week. My husband contacted Sierra Air and they scheduled a technician to come out the next day. Wayne was so friendly and examined all the equipment. He explained to me everything that was going on with our system. He gave us options from just adding coolant to repairs to a new unit. He wasn't pushy about selling us a new unit but did show us pictures of the system in our attic and it is pretty clear our unit needs to go see Jesus. The experience made it easy to trust them and we will be purchasing a new unit through them soon.

Wow, customer service is an A+! New home construction. No heat, not at the fault of Sierra but the builder for lack of communication after the gas was turned on. Contacted Sierra spoke with Diana. Sent me link to trouble shoot problem. Unfortunately, did not solve issue. Sent email on Saturday night. Contacted first thing Sunday morning. I wasn't expecting to hear back from someone until Monday. She immediately scheduled a service tech to come out same day on a Sunday. Service tech Adam was fantastic! He is very detailed and even placed shoe covers on prior to entering home, that was a plus! He quickly solved the problem and was done in no time. He is very knowledgeable, explained what happen and answered my questions. Overall, a pleasant experience and professional.

My thermostat wouldn't connect to my phone. I tried resetting it 100 times - it's digital so super easy. Sierra Air said it would be $89 to come look - they installed these. I told the nice lady on the phone that for $89 I'll just call Honeywell and get them to back their product. She said I could use the $89 towards parts/repairs. Cool.

The nice man comes out and tries to reset it 100 times, just like I did. Didn't work. He popped the thermostat off (it literally plugs into the wall) and put a new one on and still didn't work. He talked to his manager and they said to contact Honeywell, because they can't help.

I'm not sure what parts they thought they'd fix - this unit just pops in and out of the wall, they had me thinking they'd open the unit up and problem solve. The tech suggested I keep the new thermostat they installed - I'm not sure why I'd pay them for a new one when it was doing the same thing the old one was doing? I had him put the old one back on (2 years old - brand new house). So yeah - I could've just skipped all this since there was really no technical work done, just resetting like I already tried. He left, I got the bright idea to unplug my WiFi and plug it back in and boom - the thermostat connected. This was a waste and I will bypass them next time. But if they give me my $89 back I'll let them use my pro-tip on future customers. ‍

During the past four years, we have had excellent, responsive and dependable service from Sierra.
3 months ago we had to replace the fan motor in our air conditioning/heating unit in the casita. After two months it became apparent that the bearings on the fan motor were making loud vibration noises.
Sierra sent out a service person (Dan) who worked on the motor from 7pm until 9 pm ( even after nightfall!) after checking it thoroughly he stated that there was really nothing wrong other than just the unique vibrations of that brand motor. He said, however, that if the sound was bothersome, Sierra would just replace the motor... no questions asked!!! How amazing was that in today's world!!!
Dan returned today with the new motor and installed it promptly. When he was finished he had us listen to the motor running and it was fine!!!
He than politely asked if there were any additional issues he could resolve.
Everything works well and we were pleased with Sierra and extremely pleased with Dan the service person.
I would recommend Sierra and definitely request Dan as a service person !!!!!

Five stars sounds impossible for a HVAC company but Sierra works they're @55 off for their clients. When I signed up for the maintenance contract, it was comparable in pricing and easy to pay with monthly installments. I scheduled an appointment with the tech they said Lee would be here for my first service... Lee was EXTREMELY professional, courteous and most of all, knowledgeable. He Showed ID, had a well-maintained vehicle, clothes were professional uniform, wore booties, used ladder without bumping into anything and cleaned up afterward, no dust, insulation etc... He took quite a bit of time to do the service but when he was done and he sat down to review I could tell why. He had everything documented with pictures and notes and actually described to me in layman's terms how my system was faring, what wear he currently saw and what needed to be done to maintain this unit. He explained how the HVAC works, why desert climate affects particular parts of the system and what to expect in a timeline of how this system should operate when maintained properly. I asked a ton of questions and Lee was patient, polite and extremely well versed. I appreciate the fact that he was not worried about getting to his next appointment, he said that I am the only customer he has today, if I need to be. It seems to me they don't schedule these techs with 5 or 6 customers a day, when they have completed a job, then they can get another one. These people are thorough, competent and worth every penny especially when they remain so professional in 114-degree temps. I had a follow up visit today with another tech named Eric, this consistency followed, professional, uniform, booties, knowledgeable, and cared so much about making sure I was content with the follow up. My unit seemed a bit loud and he figured out that the vibrations had shook a nut loose and the outer case was shaking a bit. He secured the unit and even placed a bit of foam in for insulation to keep it from rattling. Very diligent, kind and professional. I appreciate this attention to detail. From Paige the customer service agent to the tech's in the field, your efforts are appreciated. Bravo!

Our thermostat went dark out of nowhere so we contacted Sierra LLC through their 24 hour online chat to book an appointment. It was very convenient. They confirmed the date and called us an hour before the technicians would show and they showed up within that timeframe. Eric and Dan were very professional. They fixed the problem, made suggestions and gave lots of options (no used car salesmen vibes), answered our questions, and were friendly and respectful (even entered our house wearing masks and booties). We highly recommend this company and would definitely contact them again for future work.

Service was good when I could get it but they tried to sell you parts not really needed - e.g. run capacitor. Scheduling is always an issue with these folks, even when you have a maintenance agreement. Better figure on three months out and you have to call them to schedule the appointment. I'm done - finding a closer service provider.

HORRIBLE BUSINESS. DO NOT USE, ESPECIALLY WITH GROUPON PURCHASE. I MADE AN APPT 3 Weeks ago and today I get a call that they can come within an hour (great) it was 8:30am. It's now 11:40am and no call/no show. I just called them (Tammy) and she can not even find the appt. I told her to forget scheduling me again. I would not use this place. I want my money back!!!

I signed up for the SAM program after reading the reviews and talking with the team in the office.

The tech did somewhat of a thorough job for the AC checkup, but it felt like a fishing expedition for recommended repairs, and at the end it was confirmed with the recommended items totaling $3,400, and a suggestion that the indoor portion of the units be replaced because of their age. One of the recommended items to pay for was on the list for maintenance.

Severely disappointed.

I've done business with Sierra for several years. They have always treated me with deference & honesty. Three summers ago my air conditioner went out at 3 am. It was 92º in my home. My mom is 92 and the heat was really bothering her. Sierra called one of their technicians to wake him. He came over & fixed the air in the middle of the night! That was the reason, when my HVAC system went out last summer, I used Sierra to replace my old system. They are great! Look no further.

Just had my water heater serviced and I have to say it was so easy and professional. Ruben Dominguez did the best job. He's quick, communicates well and very professional. I highly recommend him for your plumbing needs. He provided me several options for extending the life of my water heater and we all know how that's needed here in Vegas, but didn't pressure me. I will definitely call him again.

I am more than disappointed with this company that I have done business with for 10 years-
They have doubled billed me on 2 different credit cards for over a year.
I neglected to check my credit cards and compare billing. the agreement with them was for $25.00 per month for semi- annual heating and air conditioning inspections.
they have collected $100. per month for over a year. I contacted an individual who claim to be a manager over a week ago and emailed her a copy of the over collections noted on my credit cards. She has not given me the courtesy of a response for resolution. I have not identified a person has more authority than this person who answers the phone. If a responsible party for Sierra is reading this, I would appreciate your response.

Our technician Ruben was great. He was honest, personable & new his stuff. Ruben explained everything in terms that we understood. He took pictures of everything both before and after. The price was acceptable. We had a list of 8+ items, both plumbing and HVAC. When we addressed an issue about the main house regulator having to be replaced due to high PSI, Ruben determined that the PSI from the Hot water heater was correct, thus NO new regulator was required. This saved us $1,000+/-. HIGH RECOMMENDATION.

Unfortunately, we had to replace our HVAC system and went thru Costco, we knew it wouldn't be cheap due to the size of our home. The service was exceptional and the workers were very confident in their work. We did have a glitch and Sierra had a serviceman out the next morning on the 4th of July. Problem was corrected just in time for the Vegas heat.

So far I'm pretty pleased with this company. We've dealt with them 3 times now. They came out late at night when our air conditioner stopped working, which was much appreciated, and did a follow up to make sure everything was working right. This time we dealt with Wayne who was very professional and explained things thoroughly.

Initially came across Sierra AC and Plumbing while looking for a plumbing contractor to do some outdoor work. While we ultimately scheduled with a different company due to scheduling issues, Sierra AC and Plumbing reached out to offer an AC tune up service to make up for the scheduling issues.

Dan came out today and spent almost 90 minutes at our house to check our AC units, climbed in our attic and checked the equipment there, and cleaned the coils on the AC unit. They completed all that work at no cost to us and, in doing so, really changed our opinion of their company.

We'll definitely schedule with Sierra AC and Plumbing again after seeing just how great their customer service truly is.

I'd give a 0 if I could. They promised plumber out here at 10:00 pm for an emergency. No show. We stay up hour after hour. 1:20 am rolls around and I get a text message that they're on the way. They never showed up!! I called a few times and the dispatchers kept saying they will 'put a call in'. They're a joke - don't use them just because they say 24/7 - plenty of other plumbers around the area.

So I have been having Sierra come service my system every year for 3 years now. I just wanted to let everyone know how great their service is and how awesome Eric Otero is. They arrived promptly and were extremely courteous and professional. Eric even had dog treats for my dog Pebbles so they became fast friends. They proceeded to tell me exactly what they were going to do and how long it would take. They also put booties on before entering my residence.
In addition to providing me excellent service on my unit, they offered me some other options to make my unit more efficient and to maintain My system for maximum life. I was extremely happy with their service and will use them again as well as purchase their home air filtration system and other system saving products they suggested. Well done Sierra!!

STAY AWAY FROM SIERRA AIR!!!
RUDE..NO CUSTOMER SERVICE..FLAT OUT DONT CARE FOR THEIR CUSTOMERS!!
Im not one to write or call in complaints, but after Sierra Air Techs.(CHRIS & DAN) came out to our house today, there was nothing that was going to stop me from warnin people as to what a bunch of frauds they really are!!
They were called out to check on our newly put in A.C. unit which has been turning on & off every 10 minutes. We researched possible causes to go over with them, but they did not want to hear it. They shot everything down, wouldn't even listen to me (because my sister was the one who actually paid for the A.C.)
After about a lil over an hour of toying with the unit they concluded that nothing is wrong with it. We explained how our bill which is supposed to be minimized (with this new unit they recommended and sold thru Cost Co)..will now be even greater than our older one. They acted like they could care less. They were RUDE, didnt listen, & in the end after they left saying everything is fine....which is B.S. our A.C. unit is still turning on and off every 10 minutes.

While the customer service was good the actual service/price left something to be desired. First, I seriously doubt you will be able to get any service from Sierra for less than $~500. My furnace wouldn't heat so I called Sierra LLC. They decided the pressure switch was bad and had to order it. A week later they returned to install the part. The furnace again stopped working. Come to find out, with some research by myself, they installed the wrong switch. Further, if you look at the manufacture date of the switch they installed, it was before our home was built. So I question if this was in fact a new part or it sat on a shelf for a really long time (~7 years). I researched the price of this switch which sold for $39 downtown, but Sierra charged me a mere $485 for the part and install. Now I'm all for a company making a profit, but this part literally is one screw and a generous 10 minutes of time to install. The actual problem was a plugged exhaust vent, not the actual switch (no part required). While I'm sure your Sierra experience will vary on the technician you get, there is no accountability or quality control from my point of view. Further, they were more than happy to try to sign me up for their annual servicing--rip off! Sierra LLC isn't welcome to return to my home and if you choose them I'd recommend you question everything from parts to price.

Our air conditioner went out last week and on one of the hottest days of our triple digits so I was recommended by a friend to call Sierra Air in the AM as our inside temp was approaching 90! not only did Kim the person answering the phone, get me an AM appt that same day at 12:30, she followed up with calling me back at around 10:30 and said that a teck finished early and she would be sending him to us in about 40 min. His name was Tyler Collins, and not only was he professional and listened to us, he made sure that he started working on the problem as soon as he got here to get the unit cooling. He was great, told us up front what the issues we have with an older unit (30 yrs), and fixed our problem and stayed for almost 2 hrs to make sure the unit was working properly and the temp inside started to go down. Truly after having a lot of other air condition companies come out after the 25 years with not much satisfaction, We will definitely call Sierra Air and ask for Tyler again if we needed service!

I have used Sierra LLC for at least 5 years. I always renew my yearly service agreement with them for our AC unit. Today Josue Arriga came out. He serviced my AC last year and was so great, I requested that he be My AC guy and Sierra LLC has made my appointments with him. Josue arrived on time with mask on and went to work immediately. He did a thorough inspection of my unit. when he checked my filter, he told me it was in good condition and could go another 6 months. I was impressed. He did talk to me about a surge protector and decided to go with it. There was no pressure, just information My AC unit is top of the line and only 2 years old so it made sense to protect it. I highly recommend Sierra LLC and Josue.

5 Excellent. Jose and Randy were very professional. Explained and demonstrated the issues with my system. Honestly informed me of the costs to repair the issues. Went the extra step to track down the part required. I will certainly tell my friends of my experience and highly recommend your business to them if ever needed.

Our home is less than 2 years old and this is the fourth call for air conditioning service. Yep, we must've gotten a lemon for an air conditioner but that doesn't excuse the fact that we were told to expect a technician to call us between 2-6 pm to let us know he was 30 mins out. It is now 8:45 pm and I've not received a call nor has anyone knocked on our door. I called at 5 pm and was told yes, you are next on our list. I called back at 7 pm and was told you are next on our list, we don't stop working until all service calls are complete. I made sure to mention both times that we have toddlers in the house and could we please, please be prioritized. Each time I've called I was told we don't rush our techs to ensure that they do a thorough job- that's great but don't tell your customers to expect a call between a certain time frame when it's not going to happen.
Maybe next time your techs could do a thorough job at my house so I don't need to keep calling for service but then that doesn't put any more money in your pocket!
I'll call you again and I'm sure I'll be told the same thing and maybe I really will get to be next before the end of the night!

It's blistering hot outside and our indoor temperature is failing rapidly. Speaking of super friendly folks, I've had them out a few times now and Ricardo tops the bunch. Super knowledgeable, friendly and when in doubt reached out to his supervisor Sergey. My husband and I see why they have him in a managerial position , top notch. Thank you and your team.

Can you say switch & bait?? We called for standard air conditioning maintenance. Everything was working fine before we called. The tech came out & explained the battery in the air conditioning unit was extremely low and would need to be replaced within two months or the entire unit could go costing us thousands. He finished and left. The next morning everything failed. After work I called & they sent the same tech out. He went in the attic and said oh wow the battery in the attic failed......hmmm interesting how it failed after he was there! We paid $175.00 for a new battery.
I decided to get a second opinion from the highest rated air conditioning company on Yelp. Their tech came out and said the battery outside is just below full strength and everything fine. No need to replace the battery!!! He went as far as to clean/wash the unit which the tech for Sierra did not do. He checked the outake vents, which Sierra Air did not do. In the end the other company did not charge me a service charge!!
Don't fall for the tricks! Get a second opinion! I'm fine with Sierra Air

I had an appt for maintenance set between 2-6 for air conditioners. At 12:30 they called and said be there in 30. Great, be early. I hurried to race home to get another call that they went to another job instead. Waited all day..just got a call at 5:55 that they are on their way. I cancelled. I took the day off, lost wages, for a maintenance call that never took place. My review isn't about the work but communication. The company doesn't respect clients time why should they receive the same courtesy

We had a service done on our A/C unit in the middle of the summer last year when it went out. They were quick to respond and even quicker to get out to us and get our unit fixed so we didn't have to suffer in the heat. They honored our parts within the unit that are under warranty as well.
We need to get our units tuned up for this upcoming summer and I'm more than happy to be giving Sierra a call to perform the service.
Thanks for keeping us cool!!

My A/C has been slowly dying for two summers now. I have had numerous companies come out give estimates and repairs - basically I had an idea how much a new unit would cost. This time I called Sierra Air Conditioning. Hands down, the most professional company I have done business with in a long time. From start to finish, the service was top notch, the administrators in the office were spot on, and Chris Ramsay could not have been more helpful. I ended up paying much less than I had been quoted from other companies and, although buying a new A/C unit is not a fun purchase, Sierra Air Conditioning made it a painless process. I also have a rental property and when I need A/C repair, I will call them again. I highly recommend them to anyone. I do hope that Yelp keeps my review this time, as it keeps getting mysteriously deleted.

We called Sierra for a a/c update since are home wasn't cooling and told us they would be able to send a tech the same day. We then got a notification saying the driver would be there before 9pm , Novert showed up around 8pm and what a amazing tech very friendly, knowledgeable, funny he showed us how to work the thermostat explained how things worked should us how to use it and all around a amazing guy. If you ever need someone to work on your cooling or just teach you the in's and outs ask for Novert

If your site says you do 24/7 emergency repair and I call you on a Saturday afternoon because my house is 90 degrees and climbing, don't tell me you'll send someone out on Monday. The best part is, we had a tech here the day before but because the AC happened to be working while he was here (after I had to leave it turned off all day) he said he couldn't diagnose the problem. We won't be able to live in our own house until Sierra sends someone to fix our AC. Required to use this company because it's who our leasing company uses.

Absolutely terrible service. We have had Sierra Air out 4 times in the past month for the same problem that remains unresolved. Why a less than 4 year old unit is having so many issues is also a mystery. The first visit, they changed the capacitor and the fan for which we paid $400 labor even though the invoice appeared as if we were charged for the part (which should be covered). Less than a month later, the noise returned at which time the same technician arrived and apologized profusely as something was not connected and installed right on his end during the first visit. He apparently fixed the problem he apparently caused and left. The noise continued again and we called back to state the issue was still unresolved and requested a different technician. This time they told us they would send a senior technician out. Initially, the senior tech tried to immediately dismiss our concerns until he heard the noise for himself. He then proceeded to bad mouth the first technician stating he would be sure to tell him how he messed up (all in front of someone he was apparently training). He fixed the previous technician's apparent mistake of the fan installation (according to him) and left confirming that the issue in fact had been resolved. The next day, the noise returned again. We immediately called Sierra Air stating that someone had been out to fix the persistent issue 3 times now. Even with the repeatedly unresolved issue, we needed to wait two days for someone to come out....again. The same senior tech returned, listened to the noise (we were sure to record it so he could not dismiss the issue), and he was now confident, that the noise (the same noise it has been making the whole time) is now due to the compressor being bad. Not sure why we have gone through so many iterations of name that problem but alas, this is the newest sure thing to the tune of over $1200 (if we sign up for Sam's club that is, otherwise, it will be more). I called sierra air again to inquire why not only have 4 visit have we not had a resolution but why we are being charged $1200 for a part that should be covered under warranty. I was told the part is covered, the $1200 is for the labor! Initially we were told the rate was $89/hour for labor so explain to me how this compressor is going to take over 13 hours to install?! We are extremely unhappy with this and feel that Sierra is taken absolutely no responsibility or initiative in fixing this issue.

Update: The manager, Sergei, completely turned this experience around. Despite the issues with the technicians that were dispatched to our home, Sergei reviewed the notes from each visit and recognized the issue was never truly addressed or resolved. He went above and beyond to make things right, address our concerns, and get our unit fixed once and for all. Though it would have been nice to not have to get to this point, how it was handled when we asked to speak to a manager was very good. His response is truly why I updated the feedback.

Our home was built in 1997, ten years later with the rising cost of electricity and the A/C units not working properly we decided to replace our condensing units with more energy efficient equipment. We obtained three proposals, two of which stated that we must also replace our attic furnaces and coils because the newer units would not work with older equipment! Sierra took the time to explain the operation of A/C systems and installed only the condensing units along with a huge energy savings! (As a comparison, since 2007 our neighbors have repaired or replaced their units with original type equipment thinking they were saving money but since then our power bills have been half as much as theirs...their loss our gain!) We were extremely pleased with the fact we didn't have to replace everything all at once and we saved a lot of money using Sierra!

This past month, our heating units began to fail, so we called Sierra. The Technician was very courteous and thorough with his diagnosis to either repair or replace the furnaces. Knowing that the units were already antiquated we chose to replace both furnace/coils in the attic. Returning the next day, the Sierra installation crew was the most professional, knowledgeable and courteous group of people that have ever worked on our home, completing the job in just a few hours! Afterwards my wife commented they left the house cleaner than before they arrived! The new units are now working fantastic and are much better than the equipment installed by the builder! We are looking forward to even additional energy savings!

Thank you Sierra for the great job and superb customer service!

Outstanding job and excellent customer service by Derrick and Joshua. They were on time and very informative of what they were going to do. Both showed professionalism and was very approachable when I had questions. After the job was done I was given a thorough breakdown on what was their concerns and some recommendations on how to approach it. I don't know any other company since I moved to Las Vegas that showed a better work ethic then these technicians. I definitely would recommend Sierra AC and Heating! Thanks guys!

The technician was very knowledgeable. He explained what he inspected. No repairs were needed. Checked our filters, he mentioned that we have very high quality filters. Protecting the health of my family and pets.
Very pleasant conversation with Matt.
I will be renewing my contract with Sierra Air for our A/C and heaters needs.

Thank you

They have come to my rental house for the last 3 years to check everything and make sure it was running efficiently blah blah blah. Well each time they come out, I tell them the A/C is garbage.
FINALLY A man named Matthew Dodson came out and immediately knew the problem. I wasn't crazy, the people who installed the units and the people who signed off on inspection were crazy. My system was basically installed missing essential parts. The air mixers don't exist and the coolant line is mixed with some other line. I'm not a technician. Anyway why did it take several people to see the obvious.
I mean the wheels aren't on the car and that's why it won't go anywhere!!!!!
I would've have given them 1 star if not for
Matthew Dodson.
Their service on the phone is pretty good. They don't communicate with the drivers that well but I'm used to that. But who's trained over there.
They seem to have appt availability that suits your needs and they are always on time and if coming early, they cYou get an extra 2 stars for having Matthew. If I would have heard the news about my unit 3 years ago before paying $400 mo for AC you would have gotten 5. Hired trained people or spend the money to be sure they ARE trained.
Matt and Zach came back out to my house after reading the review and made everything right. They resolve the issue that they never spotted before. I've never had someone care so much. They stayed all day until it was fixed properly. Great job to Sierra Air, Zach, and Matt for all their hard work. I don't believe the ac has ever worked so well. Even though they never found the problem before they were always professional, courteous and on time. They were at my house 8-4:30 today and fixed the issues.
I will definitely recommend this company. They find the problem!!!

As a SAM member, I recently had my home winter maintenance performed. A few days later, I noticed my home heat was not turning on. I called for an emergency service on a Sunday, and technician Jordan arrived and inspected the heating system. Jordan determined the issue was caused by the last technician. Jordan was quickly able to troubleshoot the issue, address it, and follow up to correct the problem.

I was truly impressed by Jordan's honesty, integrity and professionalism.

The next day, Jordan returned to make sure everything was working properly and safely.

Sierra is fortunate to have Jordan on its team.

As a result, I have requested that Jordan be designated as the technician to conduct maintenance on my home.

This experience has reinforced my decision to choose and continue to use Sierra as my HVAC company.

Waited far too long to get a check-up on our systems. John S was fantastic. The company clearly has great COVID systems in place and he was respectful of space and wore his mask, even outside. Very professional throughout and thorough. Loved that he took videos in the attic and showed us exactly what was happening and what the company could offer. Pricing is fair and there wasn't pressure to buy something that we weren't comfortable with. Happy to recommend them to my neighbors and will be joining their monthly club in the future. Thanks again to John S for top-notch service!

Ruben Dominguez came out to our home for a toilet call. Plumbing has been added to the services of Sierra. Wow, was he good!

Ruben wore the booties, did all of his observations on the toilet, gave us lots of options, and we ended up replacing the flapper!

I would highly recommend Rueben! He was fantastic!

Sierra is my go to A/C maintenance company. They are trusted, reliable, and honest. I signed up for their service plan which is very affordable, and also had them install an Whole-Home air purification system. I know I can always count on Sierra. And I can count on Greg as my A/C tech every time. I'm impressed with their honesty and integrity.

We have recently moved to Las Vegas into a newly built home. When our air-conditioner units seemed unusually loud we asked for a service call from the HVAC contractor, Sierra Air Conditioning and Plumbing to see what could be done. We were so glad that we did as the Service person Noel Bunsaan was so thorough in exploring the possible explanations that he discovered an issue with the refrigerant line, and he was able to significantly reduce the problem. Noel was not only thorough but exceptionally courteous and resourceful. He patiently explained and demonstrated the issue that he discovered and the proposed remedies available. We can now enjoy the MUCH quieter air.

My HVAC stopped working just before sunset on a HOT Sunday. So I gave Sierra a call thinking not an issue to send tech after hours and was told by their Rep they could not send anyone till morning. I'm a recent transplant from Florida and HVAC companies there don't have a problem making after hours service calls. Summers are just as brutal there as well. Anyways I was disappointed to hear that, especially note that this same company installed this 4 year old unit. They had their company name all over this thing. So needless to say I'll will never seek this company's service ever!..

I was almost a victim like 90% of the people writing Yelp reviews on Sierra Air Conditioning. Luckily, I read Sierra's Yelp reviews before signing a work order. So up front, thanks to the good people who took time to report the tactics of this company.

I called Sierra due to my AC not blowing cool air. The troubleshooter said I had a leak in the coil in my attic. When I asked for his estimated price for the repair, he said he must call the home office for a quote. I offered him a chair but he insisted on calling from his truck. He returned in 5 minutes with a quote of $2,300 for repairing the leak. I expressed my surprise at such a high price for soldering a pin hole in a copper pipe. He explained that the price had increased $500 since last year and most of that increase was due to refrigerant costs increasing. He advised me he had called a comfort advisor from his company who would arrive at my house in less than 30 minutes.

The comfort advisor (salesman) arrived with a thick 3-ring notebook full of systems and options available. The first thing he convinced me - it would be foolish to repair this leak in an old coil when I could buy a new coil for $200 more ($2,500). OK, that made sense. Then he went on about the age of the AC components in my attic (18 years), saying the equipment was at the end of it's life and, most likely, I would be replacing major components very soon. Why not buy them now before they break in the heat of summer? Finally, he gave me the price of the components he recommended - $8,632.

I told the salesman I would consider the new system, but for that price, I was going to get two more bids. That statement launched him into a line of reasons I should buy from Sierra. If I bought from someone else, Sierra would probably be back later to clean up the mess others would make. He said it happened all the time. I didn't weaken on my position so at the end of the conversation, he told me to call him if I received a lower bid. Sierra would work with me.

After the Sierra people left I went to Yelp to look for two respected companies for the purpose of getting bids. While looking, I went to Sierra's reviews, which I had never thought about before. Wow! Nine out of ten reviews slammed them.

I called two other two highly rated companies. Both estimated $500-$600 for the repair I described but they would have to come out and inspect the system before providing an exact quote. One was able to come the next morning. Because of the company's very high Yelp ratings, my comfort level and the price he quoted, I said OK and he fixed the leak in less than 2 hours. Ninety percent of the refrigerant was gone so I paid nearly the maximum price - $510 for the repair, a full charge of refrigerant and testing.

I told the repairman my system was 18 years old and asked him if he recommended replacing the main components. He said no because these components can last much longer with proper preventative maintenance, which I do.

I called the Sierra salesman the following day as I had promised. I told him about getting the leak repaired for $510 and told him I had read Sierra's Yelp reviews after he left my house. I let him know I would be writing my own Yelp review. He asked me not to write until an owner or manager from the company talked to me. I agreed.

The next day a Sierra senior manager called me and asked for my story. After hearing me out, he discussed two reasons for the high quote. First, the quote was a mistake - it should have been only about $2,000. But the reason he elaborated on most was that Sierra is a very large company and their overhead is high, therefore they must charge higher prices. Really? 450% more than two other quotes I received from highly rated companies for repairing a small leak in a copper pipe? Then the up-sell encouraging me to spend $8,600 for equipment that wasn't broken? I assured the manager I would write the next Yelp review, so here it is.

If you doubt my story, read on through the Yelp reviews of others who have had experience with Sierra. You will probably notice that most of the negative reviews sound the same. There's a reason for that.

By the way, Yelp originally came to me via COSTCO. This review is also going to COSTCO management in the form of a personal letter from me.

Good Luck with your air conditioning project and thanks again to the people who take the time to write Yelp reviews.

Best AC company in town! Very knowledgable and professional technicians and friendly customer service staff. In this day and age, when other companies try to take advantage of you any chance they get, this company takes pride in their work and will take care of you any time of day. Very happy with their service and will continue using them as long as they are in business!

Where do I start!! I was at Costco earlier this year and a Representative from Sierra Air Conditioning & Plumbing asked me to set up a service appointment on my AC unit, I agreed. A technician came out to check the unit and found over $5000.00 worth of work that range from immediate attention to delayed for later. As he was explaining the work I suddenly remembered I had a home warranty. I paid the $99.00 service fee and call my home warranty. They advised I get an annual service check. I set up the appointment and 2 days later they came out. The technician checked my AC unit and advised it was in great condition and it only needed cleaning and a new cap. Total cost $85.00! Do Not use Sierra!!!!

I've been without a working air unit for three years. This year was finally the year I could afford to make the move to repair, and after 5 other quotes, I am so happy Sierra was my choice, and I didn't hesitate. I will explain.

I scheduled an appointment the day before, and they showed up at my house the next day at 9 am. During the consultation, the gentleman was very thorough. This is where my hesitantation for other companies would make me vote no, but Sierra doesn't play games. [OTHER companies will just look at it for a few mins and automatically say what they think you need.] They get into ALL the areas to properly assess everything so they don't miss anything. He took about 25 minutes before he finally said he was finished and would be right back to go over everything. Once he returned, we went over every detail of what they have options wise along with photos he took of the units I have. After going over everything, I did not hesitate and began the process. Another fun fact, they were a great price compared to others I was quoted, so that was a plus.

After we finalized the paperwork, I was nervous cause I was used to the other quotes, saying it would be a few weeks out to repair. However, Sierra, same day!!! We finished the process by 11am. The installation team showed up at 1pm to begin installation.

Now, this team! They deserve huge kudos! I know some people can say they have a nightmare of units well mine was sure one for the books! This team had to face a nightmare. The unit outside was original from the 70s, and when they started rolling it away, it fell into pieces. The unit in the attic, besides it being also original, there was the basting foil pans they found that was for the water run off? Not to mention, the unit was just yikes. They also found non-existence of paddings, etc., that it should have, as well as the pipes liners they replaced all of it! These two men who did the installation have a story forever. I made them feel at home because these men didn't finish till 11 pm. It was a very long day.

I am so grateful for them all and the company itself. I am very happy with my choice and I would recommend them to anyone.

I called Sierra LLC to see if they did water heaters and found out that they did. My water heater busted on Saturday night. I called Sierra and they were out in about an hour. Ruben was the nicest guy. He was wearing a mask when he showed up and was very polite. He came back Sunday on time to replace the water heater. The price I was quoted was a little bit to high for my liking but Ruben gave me a little bit of a break. I didn't mind paying the price for the great services I received. I would definitely recommend this company.

The Tech Barry S, arrived right on time and did a great job, he explained the work that he had done, and told us about some A/C filter options that we did not know about.

Great service, extremely courteous staff and techs and they get the job done! Very happy with the service they provide! This time around, it was a maintenance service and tech Moises explained what emergencies needed attention and what we can wait a bit longer to fix since we are not made of $$$ :)) really appreciate the honesty! I would strongly recommend Sierra to all our friends and family! Thanks guys!

My air conditioner started making a loud whining noise last week. It is a brand new house, so the air conditioner is also brand new. Sierra came out within an hour, and fixed the issue. Technician was very knowledgeable, friendly, and explained everything. Good follow-up the next day from office staff. RM

I reached out to get a quote for a new AC install and a lady called me from Sierra and she advised me that she will give my quote to a tech and they would be out later that day and that the tech would call to confirm, never heard from anyone. On Thursday I received a text from Sierra saying that their technician would be at my house on Friday and the tech would call me 30 mins from my house. Never heard from anyone so that means for 2 different days I waited at my house on Fridays and never heard back from this company!!! Not professional at all I would not recommend this place.

My AC needed the seasonal check. Fabian the technician who was assigned to the task did an amazing job. Not only did he wore a face mask, which is so important now, but also shoe protectors.
He cleaned and service the unit, changed the filters inside at the very high ceiling and marked them with the date. Also had to go up to the hot attic to ensure the blower etc. is working correctly, checked all the vents to ensure the air was blowing strong.
He answered all the many questions I had. Was super friendly, went out of his way to change a light bulb on the (for me) unreachable ceiling.
Overall a great tech who followed the guideline correctly. Kudos to Fabian for a job well done.
Sierra replaced the AC and Heating unit last year. Was so impressed with this Company and the certified technicians. This is the company to keep!!!!

Sierra was supposed to come out and install three new thermostats. We were led to believe the cost was an $89 service fee. The following is a copy of Sierra's portion pf the conversation:

T-stat are the one item we can install with the home owner supplying it. We can also supply it. The difference we do not warranty any t-stat that the h/o supplies. We do warranty our t-stats. There is a $89 service fee. What time works best on Monday 10-2pm or 12-4pm?

The technician Matt was extremely pleasant. He texted us 30 minutes before arrival and was wearing a mask. He looked at the thermostats and informed us the install was actually $189.00 EACH but he would waive the $89. service fee. I explained there must be a mis-understanding as to the Yelp quote we were given. He call his supervisor who al reiterated the job was going to be $567 plus tax. That ridiculous price is for a 15 minute job replace three thermostats on a completely functioning system. This was a classic bait and switch which would have probably worked on someone who didn't know better. Shame on you Sierra for your deceptive price estimate and charging people 189.00 for EACH thermostat change.

I want to reiterate the technician Matt was extremely pleasant and apologetic. Do yourself a favor and find reputable HVAC company because Sierra is not one of them.

Sierra customer service e has been excellent. Sierra has responded quickly and professionally. A special thank you to Zack who has taken the effort and gone the extra mile to resolve the issues with my air one of which was no fault of the company. Also a thank you to Johnathon the last tech who serviced my unit. He was professional and carefully explained everything to me. THANK YOU Sierra.

We are so thankful for Jonathan W. that came out to our home and rescued us from the heat.
We paid another company, who did our install to come and check out our AC when it started to act up. He couldnt figure it out, even after coming out twice to our home and their service fee was $150. They didnt charge for the second visit was which two days later from their first day. When our AC went out completely, 6 days after their second visit. we were told that we would have to pay the $150 service fee again. We said no and reached out to Sierra who came recommended by a friend.
I called Sierra at 2pm, explained that my AC is completely out and at 3:30pm, Jonathan was ringing our doorbell. He checked the outside unit, everything was good and then went up to the attic. He spent a long time up there checking everything, in the 90+ degree. I wanna say it couldve easily been 100+ degrees because our home was already 88 degrees with stand up fans running. He was even able to replicate the noise that we complained about to the other company. In the end, our circuit board needed to be replaced which was under warranty and he recommended a second transformer to help with the electrical load in the attic. I was really pleased with the cost, i expected a comma in the total and there was none. In fact, the cost of everything with labor was cheaper than an iphone 11!! After 5 hours, 4 of them probably spent in the attic, our AC was up and running and we didnt have to spend another night sleeping with no air. THANK YOU JONATHAN!!!!
We were totally won over and even signed up for their program to have them service our unit twice a year.

The customer service is second only to their technicians. I have a contract with them to service my HVAC. The technicians are always professional and very helpful with educating me about the best way to keep my HVAC healthy and up and running. The pricing is fair and I couldn't be happier. Thanks Tim Casaus for the exceptional service today.

I want to highly recommend Sierra Air Conditioning and Plumbing and especially their top notch plumber, Ruben. He was absolutely fantastic in explaining all of my brother's plumbing needs and took as much time as needed. He is an excellent plumber who really knows his business and is a pure pleasure to work with. Ruben will be my brother's plumber from here on out. Plus, I want to sing the praises of Manny, who helped Ruben install the new water heater. He was a pure delight to work with as well. Also, the office staff were great! Everyone at Sierra has your best interest at heart and I highly, highly recommend Sierra Air Conditioning and Plumbing. Thank you, Laurie G.

I'm not sure where all these bad reviews are coming from, these guys are without a doubt the best in the business. I have been using them for years for service and replacement issues. Recently our a/c had been giving us problems because it was an older system so we scheduled them to come out. Not only did they call ahead to confirm our appointment but they arrived on time (which is not common in Vegas). Our tech, John T., was very respectful. He knocked before coming in an out, he wore booties on his feet to keep my floors clean and he didn't make any unnecessary recommendations (thank you!). We ended up having to replace the unit but the quote was extremely reasonable compared to other companies and we also picked a service program to keep the unit functioning properly. As an added bonus our power bill has gone down drastically so I'm glad we didn't wait any longer. All in all, I would highly recommend and will continue to use them for all my future a/c stuff! You guys rock!

Three years ago my air conditioning died in August (Las Vegas!). I called a couple of companies and decided on Sierra because that is who Costco uses. Everything was fine for the next year. The following year I signed up for their maintenance contact. Earlier this year, I decided to get the Filter Box. Sierra contacted me the day before the install was to happen to let me know all the parts were not in and THEY picked a day to reschedule the install. That was pretty presumptuous to me since that date was a work day for me. I contacted them and rescheduled for two more weeks which was more convenient for ME the customer. I also advised them that if they showed up on the date of install (by the way, I had already paid them IN ADVANCE!) unprepared I would cancel and expect my money back. They showed up without all the parts. I canceled and it took several weeks for me to get my money back. I contacted another air conditioner company and had them install the filter box and a UV light. They sold me on their maintenance agreement which also included plumbing for 3 dollars more a month. I called and advised Sierra to cancel the maintenance agreement when it ended in August. I called again the next month and reiterated that I wanted the maintenance agreement canceled in August. I called again the next month to remind them I was not renewing and my last payment should be in August. As you can see, by this time I did not expect Sierra to do what they promised me they would do. Well, my fears were rewarded when I was charged in September 2020. I would look for another, more reliable company. I cannot recommend Sierra.

I had Sierra Air come out to my house to fix and A/C issue. I called and let them know my A/C was out and my baby boy was getting extremely hot and they told me not a worry! They got someone out right away even though it was a Sunday! I'm sure they are slammed with this 118 degree weather but they made it happen! They sent a technician named Izac Reza who was a god sent! he was great. I have two ginormous doodles and with Izac being in both the house and the back yard there was no where I could tuck them away. not a worry with Izac he was very cool with the pups and always made sure they were secured in the house or the backyard so I wouldn't have to track them down! he was great with communicating what he was doing and what issues the system was having. he quickly diagnosed the issue and fixed everything right away. we are back to a nice cool house! thanks Izac. if you are having an issue dont hesitate to reach out to Sierra air. and definitely ask for Izac Reza!

I had really high hopes about this company based on their online reviews, as well as their website. After I put in a request online at midnight, I woke up to a VM saying they could fit me in even earlier. Score! (or so I thought)

I called back around 8 a.m. and wait for 15 minutes to a looped recording, then pressed '1' to have someone call me back. Ninety minutes later, nothing. No call.

I call the office again around 11:45 a.m. and finally, someone answers. She confirms that yes, they can send someone out tomorrow, sometime after 12 p.m.

'Tomorrow' comes (that would be today, Thursday) and around 4:30 p.m., I reach out via online chat b/c no one has reached out and it's getting later and later. He says he can't help me, but that he will have dispatch reach out to me.

I asked them to text me an idea as to when I can expect my tech? Instead, they call...she says they run people all the way up until midnight, that my time frame is 12 HOURS, but rest assured, someone from dispatch will call me when they're on their way!! I was like, 'You want us to sit at home and wait for 12 hours for one of your techs to come?' Yes, that is what this company wants you to do. She explained that technically, they don't want you to sit at home, that you can do other things, but you don't know if dispatch is going to call 90 mins or 9 mins before the tech arrives.

I know it's hot, I'm sure lots of people are having trouble w/ their AC right now, but seriously, this company acts like it could give a d*mn.

I go back online, tell dispatch to cancel my service, no need for them to call me back...and so after doing that, I get a call from dispatch around 5:30 p.m. saying they're going to send a tech! I swear, the right hand doesn't know what the left hand is doing w/ this company.

I'm going to find a company that can actually schedule an appointment, or least give a reasonable time frame, for arrival....and hopefully, they answer their phone or maintain an adequate call back system.

I assume Sierra is who installed the HVAC system in our home, as the builder recommended them to us for maintenance. We've been using them ever since, about 8 years now.

We do the semi-annual maintenance which I feel is reasonably priced. The person working (it's not always the same person) doesn't always find something that needs to be replaced or upgraded but they do give us in-depth reasoning when they do want to replace something. They also replace our air filters for us, which though expensive, is really worth it.

We tried to buy our own filters this last time to save a few bucks and it turned into an almost nightmare and we will never make that mistake again. Apparently, the cheap filter we bought got sucked up to far and blocked the airflow which was icing over the condenser (or something like that) and if we hadn't called on Saturday night, and they hadn't made an in home inspection at around 1230am, we would have lost the whole thing and it would have been way more than the few hundred bucks it took to fix. Lesson learned.

We've actually had to have someone come out in the middle of the night before, during the pandemic. The best part of their customer service is that it's available all the time and they do not gouge you to come out. Four stars though for not being able to give a good time window. This last time we had no idea when someone was showing up and had to wait up pretty past our bedtimes. Even a 4 hour window would be nice.

TL;DR Sierra is fairly priced and they are almost always available to help with good customer service. The tech are always friendly and helpful and respectful of your home. Would recommend.

Our grandparents and parents used Sierra for years. My wife and I have had the pleasure of being served by Sierra for the past 5 years. There is nothing like their 5 star service they provide each time we have maintenance performed! There is never a sales pitch and they are always honest! When Daniel arrived at our home, he inquired about how our system was operating. I explained some concerns I had and asked if he had any suggestions. After completing our unit's maintenance, he met with me and took the time to write down several different options regarding my concerns. I was amazed by the amount time Daniel took explain everything! I now fell at ease and know that the issues I brought up can be easily fixed. He is a true professional with an ability to connect with people. Thank you Sierra for your years of service and thank you for hiring the very best!

In December, we had an issue with our furnace and had no heat. Sierra, who installed our system, came right out to take a look. Although it took three technician visits and several days to fix the problem (had to wait for the part), we were impressed by the knowledge and responsiveness of each tech and Sierra as a whole. We signed up for the maintenance agreement, and today was our first service.

I awoke to a reminder text of our appointment, which I appreciated, since it was scheduled about 6 weeks ago. We then received a call telling us our technician would arrive within the hour, which he did. Derrick Lakey was our technician, and I was impressed from the moment he walked through the door. He wore his mask the entire time, which I truly appreciated. He was knowledgeable, courteous and friendly. He got right to work, and explained what he was doing every step of the way. We have 3 systems, so Derrick spent almost 3 hours at our home. I was so impressed with the excellent service he provided - he didn't try to sell me on additional products or services, but did recommend a few things. It was such a pleasant experience that I immediately called and scheduled our spring maintenance with Derrick. He exceeded my expectations in every way!

If you need a check-up on your AC or heating, please call Sierra Air Conditioning and Heating. They were able to schedule me on a day that was convenient for me. John, my technician, explained everything that was going on with my AC and heating units. He showed me pictures of both units and the areas needing attention. He provided me with multiple options regarding necessary repairs, and prioritized them for me. I feel much more confident knowing what's going on and what to expect with my AC and heating. I will continue to use Sierra Air Conditioning and Heating for my future needs.

I can't say enough about how great these guys are. I know the owner Rocky and have done service work for him at his home with my garage door company. I called on his company after I drilled a hole thru my main gas line in my garage. They were out the very next day on time, right when they said they would be, assessed the situation and got to work right away. Melvin my technician was very polite, professional and straightforward. He was able to complete the repairs in a couple hours and had everything back up and running by the next day. My family was due to arrive at my house the very next night and we definitely needed gas to cook the food we had planned on eating. Not to mention a shower before..lol Thank you so much to Rocky, Melvin and the rest of the Sierra team! You guys rock and I will be referring any and all of my clients your way if they need plumbing, AC and/or heating. They have all the advanced equipment and know their trade impeccably. Call Sierra Air, you'll be glad you did!!

I don't typically write negative reviews, but this experience was so bad it's almost funny. (Except it's not funny, so I apologize for the lack of hilarity that's about to ensue.)

I contacted this company because they're affiliated with Costco, thinking (incorrectly) that there would be decent rates for AC service/install.

When I called to make the first appointment, I explained we're looking into whether we needed to repair or replace our current AC unit, as it's running inefficiently and costing an arm and leg to boot. The gal said, It's a 90 minute to 2 hour appointment to go over everything. Can you do 10am-noon? I said sure, and we set a date. Date arrives, as does 10am...no Sierra rep. I call, and they inform me that 10am-2pm is my appointment window, and the rep would be there by noon. Since I was told the appointment was a 90 minute to 2 hour process, this wasn't clear when the appointment was set. Strike one.

At 11:30 I was called by dispatch to let me know he was on his way. At noon, no rep - so I called and let them know I needed to head back to work by 1pm. At noon I got a call saying he could be at my house in 30-45 minutes. I told them I'd have to reschedule. Strike two.

Yesterday I had my second scheduled appointment, again from 10 to noon. At 8:30 in the morning I get a call saying the Sierra rep was heading my way. Umm...huh? I let them know I wasn't available and was heading into a meeting, but I would be at my house by 10 am for our scheduled appointment window. At 11 am I called to check the ETA of the Sierra rep, and the gal on the phone said, Oh, you're home now? I'll have them add you. I told her I'd been home and available since my scheduled appointment time of 10 am and hung up, frustrated. Once again noon arrives and no tech. I call and they tell me he's 30-45 minutes away. Ugh. Dude arrives around 12:30, and we walk over to the AC unit in question. He looks at it and is like, Yeah, you'd need a tech to tell you if it's running inefficiently. Maybe it needs a charge or new compressor and maybe it needs to be replaced. I wouldn't know. I was under the impression you wanted to order a new system. He then tells me it would cost $50 to have a tech just come look at it, and told me his cheapest 4 ton unit would be $10,000 installed. He also told me to have a mini split ductless AC installed (to supplement the current system) would be about the same price. Strike three.

The national average for a 4 ton AC unit INSTALLED is about $5,000-$8,000 and Sierra's cheapest is $10,000? And the average cost to install and ductless mini AC split is around $1,700, so that's a hard pass. Also, who sends a salesperson out for a repair/replace estimate? If I could give Sierra zero stars, I would. Unprofessional, and definitely not competitive with price.

I called the other two AC companies I have scheduled to come out this week (appointments I made while waiting for Sierra Air) to make sure they were sending TECHS and not just salesmen. Both companies laughed when I asked, and said Of course. We're sending them in fully stocked trucks, so if there's a repair they can make on the spot, they're able to do so. I don't know what racket Sierra is running, but buyer beware and shame on Costco for working with them.

Francisco was very helpful. We recently had an inspection on our house because we are selling and the inspectors failed us for a split level reading. Francisco, thoroughly inspected and found that wasn't the case at all Which I'm sure, save us a ton of money. He was very quick too!

Yesterday my air conditioner was not blowing cold air like normal. I made the mistake of calling a company that has numerous ads on the radio all the time. That company wanted to charge me 1500 dollars for a frozen coolant line by dumping it and recharging it. ( turns out it can be done for free by just running the fan and turning off the system). Seeming quite suspicious like I was a sucker being born. I declined and contacted Sierra after a reference.

The repairman was super straight forward. Honest and totally confirmed that the other company was inaccurate about there diagnosis. Sierra got my air back up and running for 1/10 the price of what the other company wanted for bogus work. There was no need to dump the coolant and recharge the system. Due to the other company first responding on a unit that had never had a issue. Time will tell if I have a leak or if the other company let to much coolant out which a minor amount had to be topped off. The system had just ran to hard and the line froze ( unknown of a leak exist ) but Sierra will be back out to check the levels and advise as we go.

Great company. Very pleased

Due to such good customer service and knowledge. I will be calling Sierra for future issues and definitely staying away from a well known radio advertising company which seems out for cash and looking for suckers.

Update1: Finally spoke to one of the service managers named Sergei at Sierra Air. Turns out, this tech Joe blamed us for creating hostile environment. Unbelievable. Bravo Sierra Air, very convenient way to get out of a sticky situation when your tech gets caught lying. I am glad we found out about deceptive tactics and how unethical this company is before we signed up for maintenance with them. I would never let any of their techs inside my home. Who knows what else they are capable of doing to my AC and lying about. My suggestion: Stay as far away as possible from this company or learn about your AC unit and watch their techs every step of the way, don't leave them alone with your unit or you will end up with a very pricey repairs and an accusation of creating a hostile environment.

Not a reliable company at all, very deceptive and some technicians are very shady, Sierra Air management handles complaints extremely poorly.

My AC unit is only 2.5 years old and installed by Sierra Air on a newly built house.

I purchased my home in Feb 2020. Exactly a year later, Feb 2021, we started hearing some extremely loud noises in the attic. Warranty services called Sierra Air (they were the ones contracted by our builder to install our AC unit), Sierra tech came out and said he will adjust the actuator, little motor responsible for opening and closing dampers. After that the noise has stopped but other problems have started.

The following summer one of the 3 zones in the house starts to shut down, one day we have cold air, another day that zone is completely dead. But since there are two other zones that are still operational it helps to keep the house somewhat cool.

Nonetheless, I called Sierra air, tech came out, said changing filters every 3 month is not often enough, has to be done every month and left. Nothing was fixed, one of the zones still worked only intermittently. I was away for work a lot for a few weeks at a time each time and every time I contacted my service manager he was being very dismissive of the problem telling me that this is how AC is supposed to work it's just some days are hotter than others. With my ceilings being 10ft tall it's not easy to feel if the air is coming out of the vents or not without getting on the ladder plus the other 2 zones still work.

This year, as soon as we started using AC I noticed the problem again, only this time this zone doesn't blow cold air at all. I call Sierra Air, they said I'm 3 month out of labor warranty and would have to pay $820 for labor, because I have two actuators that are not operational.

Tech (his name is Joe) also says that he already replaced one of the actuators and this is what helped him diagnose the problem. What?

We saw him go up in the attic with only his tools and turns out he already had an actuator in his pocket just in case? What a scam.

Joe tells me that he's going to go get the second actuator while I consider his offer. I tell him it's unlikely that I will be paying for labor and would prefer to contact my builder's warranty services. He says he's going to see what he can do.

I go up the ladder and take a peek into the attic, there's absolutely no spare parts or broken actuators anywhere. So where did my broken actuator go?

When he comes back he proceeds to offer to waive the labor fee if I purchase their maintenance plan with monthly fee of $16. Good job in upselling, Joe!

I tell him that I need to think about it because I don't think it's fair that I have to pay labor fee for something that was supposed to be fixed last year when the labor was still under warranty.

He says -Okay then I have to take my actuator back. Which is fine, only now we want to see what he's doing in the attic. Feeling like we're being scammed I started to record our conversation. Of course Joe refused to go back in the attic, he said that he doesn't want us to watch him, just wants his tools back. We handed him his tools and he left. My AC unit was left open, we had to go up to put all the covers back.

I understand that not every tech is going to be ethical and trustworthy and I wanted to give Sierra Air a chance to fix this, and the management's response was we are going to look into this and give you a call back, we really want to help you and then nothing..

Also, I do know that AC needs to be maintained and under different circumstances I would have definitely considered getting my maintenance plan with Sierra, but at this point their reputation went down the drain when their tech got caught lying and trying to scam me.

It has been almost a week, I haven't heard back from anyone from Sierra. At this point I don't think I would trust them into my home to do anything with my AC without me watching them very closely, but I was still curious to see if they would at least try to resolve this.

Another company is already scheduled to come out, I will update this review with whatever else I find out .

We've used Sierra for the better part of 10 yrs....the last year or so has been unbelievably disappointing. I will share the last incident. We woke up Monday morning without heat. My wife called Sierra to schedule an appointment and the immediate comment was our equipment was over ten years old. A tech showed up later that day and checked our system. He showed me photos of a motherboard and a relay and some rust on the furnace sheet metal. He indicated the board was burned out and needed replacement along with a relay...... over 3 grand.My other option was a new unit for over 7k. Both these options were available the very next day (go figure). My antenna went up as they had recently done other work (a separate nightmare I won't get into). I had someone else over today. Bottom line......motherboard is ok as is the relay. There was a cut wire however, and the rust is minimal (Sierra tech blew up a photo ) .The end result was a bill for less than $100. I'd exercise extreme caution with these people if you use them .

Wish I could give more than 5 stars. I came into Vegas to visit my uncle and enjoy the weekend, turns out Thursday night one of the A/C units was not working. Called Sierra Air Friday morning and they had a tech to the house in less than 2 hrs, they found out what the problem was and said they would get the parts and be back to get them installed.
A few hrs later a truck delivered the parts and two technicians were right behind them to get the parts installed. Thank you Sierra Air sleeping was great in nice cold air. The technicians were NATE certified which I learned is a big deal and means they know there stuff.
With or with out the certification they were awesome from start to finish, technical ability, customer service, and most important they were timely and did what they say they would do when promised. I got what I paid for, actually I got more than I paid for.

KUDOS to Ulysses and Hayden! They're my to go to for my yearly maintenance for both AC unit & Water Heater. Always provides great customer service from beginning to end with a smile. Both are very knowledgeable and answers my questions and concerns making me feel at ease. I've been a client with this company for over 3 years and I love them. Thank you both for taking good care of me and my home! I appreciate you both. Keep up the great work, you both are doing an amazing job. THANK YOU Ulysses and Hayden!!!

I have used Sierra Air at several homes/Condos that I own here in Vegas. This last summer.... in the peak of the heat (of course) the AC died in my Summerlin home. Sierra came out IMMEDIATELY.... worked efficiently and neatly with professionalism.... and got me running again in no time. Awesome service.. reasonable pricing... professional personnel. I'll only use Sierra Air!

Had them come out for there annual service, tech told me that my furnace was not working properly and needed to be replaced for 14k I told him that I just wanted service that everything was working ok he tried to keep hard selling me a new unit and keep telling me how mine was not working. This service call cost me $49 dollars and I still did not get the service just a con and hard sell for a new unit I do not need.

Excellent company!!! From first contact thru their repair person, nothing but professionalism. Collected all my equipment information over the phone and arrived as scheduled. Explained what was wrong and what my options were. Would recommend to all my friends!

My favorite HVAC company hands down. I tell everyone to use this place. I just needed to use them for my house. Have them a call and they scheduled me right up for the next day. The tech Joshua C was dispatched to my house. Very clean attire and wore booties without having to ask. He was very professional and got straight to work. Joshua asked where the attic access was, brought his equipment and found the issue. Told me it was the damper motor, very happy to hear that he had one on his truck and exchanged it very quickly. He then checked out the whole system to make sure it was working properly and even showed me the pictures he took. Very very nice guy, would definitely ask for him again.

I scheduled a service call to replace a whole house air purification system filter in the attic. When I called for service , I gave the representative the model number of the filter. When service arrived they had the wrong filter and admitted the person in the office made a mistake and no replacement could be made. The tech proceeded to charge me $79.00 for a service call which I have since disputed with my credit card company because the service call was generated to replace the filter and they had the wrong filter. To make matters worse he tried to sell me a new thermostat claiming it was needed to make my purification system work properly. After doing my very complete homework I was told this was not true. My message is to always get a second or third opinion if you do not want to waste your money on things you do not need.

Sierra is a very professional company. The dispatch staff were very helpful and responsive the times I called, and the technician (Fernando) that inspected our AC unit was excellent. He was respectful of the home (wore booties, used drop cloth, etc.) and also very efficient. After diagnosing the problem, he gave me a cost effective option for the repair and ongoing service. I will definitely be using Sierra in the future.

Well, this will be the 3rd time they have had to come out. We're still waiting as the customer service agent called me at 2:30 saying he would be here at the later portion of our 'window', which was 12pm - 4 pm. It's 5:40 pm and no call from office. I did leave work early for the appointment. Ugh! Darryl was our tech both times and found the issue on his 2nd visit. Now, the upstairs is not cooling whatsoever. I'm not sure if there is a leak but to have a 10+ degree difference from our downstairs unit seems a bit extreme. Our bedroom and twins is like a sauna to say the least. We bought this home brand new in 2015 and didn't have this problem last summer with cooling. The outside until feels very warm to the touch.

I'm giving 4 stars because Darryl was an extremely nice guy and took great attention to detail when inside our home. Customer service agents could use some spark as a few of them sounded like they could care less.

Update: Upstairs is finally cooling down. Darryl found a T-fitting that had come loose and drained the system of all the freon which caused it to blow hot air. Even though Sierra had to come out 3 times I didn't mind since Darryl apologized for the inconvenience and went about explaining the issue with video.

I signed up at my local Costco to get a quote to replace my HVAC system. I received a call right away from Sierra to schedule a consultation. Shawn Brown arrived at my home for the consultation. He was very professional and he did not strike me as a typical sales man. I told Shawn I was going to get three bids and research each company before I made my decision. Shawn respected my position and then began to impress me with his expertise. Shawn climbed into my attic to inspect the duct work and air return vent space. He then inspected my furnace and changed my filter for me. He explained things to me in simple terms so that I understood him and he answered all my questions. Ultimately I chose Sierra to replace my HVAC because of their knowledge and reputation. The technicians did a great job too!

No air conditioning & still waiting 2 weeks later for a call back. I was a loyal 4+ year customer who bought 2 HVAC units from Sierra along with maintenance agreements. 1 unit went down and I called on May 25th. A technician came out that day and verified that the compressor failed and a new one would be ordered for delivery the next day. I never heard back so I called them the next day and was told that it never got delivered and would probably arrive the next day (Friday before Memorial Day). I was again told that I would definitely get a call back with an update on Friday, which never came. Two weeks have passed and I received no communication. No call, no text, no e-mail. Nothing.
If you don't mind being stood up by your HVAC company during a record setting heatwave, Sierra might be right for you. For me, it's been a complete disappointment that the company I trusted for years can't service a unit they sold and installed but, more importantly, they have proven to be untrustworthy when we as customers need them the most. All the excuses in the world can't justify leaving your customer in the dust waiting for a simple call.

Sierra is so lucky to have Tyler C as a service tech who has done a great professional, friendly, and trustworthy AC job for the 2nd time. Sierra also has pleasant and helpful employees to schedule appts. Definitely recommend Sierra LLC as the service that soars above the rest.

Our A/C kept acting up downstairs and we are so happy we called Sierra Air. Fabian was our technician who diagnosed the issue & got our parts ordered quickly. He came back with Mark to replace the parts and it has worked great since they left. Fabian was very knowledgeable, friendly, and explained the issue that he found. He made this process less stressful for us. Highly recommend Sierra Air & Fabian/Mark!

They were able to come out same day, actually within a few hours of me calling. Louis was the technician and he was on point. He not only got my ac back in action but he also have me a few pointers on maintenance of the unit. Thanks again Sierra and you will be my go to again.

1st floor heating wasn't working so I called Sierra LLC to see if they could find out what was wrong. My house is new so there shouldn't be a problem. I had different thermostats installed (WiFi enabled) when the house was built, but they were installed by a 3rd party. Sierra tech checked out the heater and it was fine. He was hesitant to work on the thermostat since his company didn't install them, but I opened it up and he checked the wiring. It was wired incorrectly. Tech corrected the wiring and all's good. He went above and beyond expectations. Because of that I'll be calling Sierra LLC for a maintenance agreement. Oh, and they came out within 2 hours of my initial call. What great service!

Do not use this company for your heating and ac needs. We are still under our Manufacturer warranty for parts on our ac unit. When we called them to come out They said that it would be a $69.00 Service call fee. Which was fine. Then the technician gets here, does the repairs(without telling me that I would have to pay for labor) and then tells me that it will be $167.00 Because of the labor cost of $98 (for 5 minutes of work), i would like to know how they determine their labor rates, oh yeah and he was trying to sell me the companies maintainance plan where they come out every 6 months check your unit and you get a whole 50% off the cost of the part. When I spoke to customer service they told me that I was more than welcome to pay the service call fee and have the technician put the old part back in and call someone else, like I would do that and have to pay more money. Save your money and call someone like silver state ac. They are much friendlier and explain things a lot better.

I think with any kind of service agency like this you're bound to get a few mixed reviews due to the complexity of what's being worked on in the wide range in skill and personalities. That said, we had a problem with our air conditioning unit in our new home and contacted Sierra through our builder's customer service warranty center.

Sierras's customer service was able to get us an appointment quickly and the technician, Adam, who arrived was courteous professional and got immediately to work.

He perform a full inspection answered a number of questions we had about the unit and found a few wiring problems which was causing the air conditioner to not properly run. In less than 45 minutes he had completed the repairs tested the unit and it was blowing very cold air and working perfectly.

I have no problem with recommending this company and their service and a special thanks to Adam for doing such a great job.

Jay came out and repaired a few parts in my AC unit in a very timely manner. We were lucky enough that he able to come by after hours because our AC wasn't blowing cool air. He was very proficient and professional and I'll always request him in the future.

When I put in a request on Yelp for a plumber, I was surprised to see Sierra LLC Air Conditioning & Heating respond, given their name. But the owner RJ responded to the work request within minutes letting me know they do plumbing and additional services. When I informed him of the issue, he didn't hesitate to offer a free estimate as early as the next day. Here I was thinking it would be at least a week before someone could take a look. He scheduled us for the next afternoon and let us know we'd receive a courtesy call, and finished our correspondence with a thank you. Much appreciated.
The plumber arrived the next day and was so polite with obvious work ethic. He cleared our issue the old school way, no fancy equipment or the correlating big prices. I couldn't believe how fast he took care of us. I have no doubt he saved us hundreds if not thousands of dollars if we'd gone with someone else. Now that I know of them, I'll be contacting them for whatever household needs we may encounter.

I had this company come to put new air ducts in my home they changed me $2900.00 3 months before they where to complete the work. I was like whatever so I scheduled the appointment 3 months in advance. Come appointment day no technician shows up. I get a call telling me he's running late. I'm like ok. Around 4pm someone shows up at my house. tells me they forgot to order the parts.he says I'm going to do your winter service on the ac. Works on the unit in the house takes the bolts out of the gas shutoff tells me they are missing. Never looks at outside unit. Now gas valve still have no bolts. So next day they show up at noon with parts then everyone leaves except one guy. The guy says they have to wait for the installer. The installer shows up at 4pm says we need more parts before we can install. Tells me we may be back tomorrow. I was done. Also I used Sierra at my rental property. They inspect my ac tell me it needs new blower motor and would $2000 to fix. I call another company they replace a circuit board for$300 and ac works fine. So they over charge don't stick to appointments. Generly don't care for the customers. Now my job is not complete let's see if they issue my refund.

Had my annual air conditioning checkup today and was very pleased with everything. The technician (Joshua C.) was here on time, did a very thorough examination of everything related to the A/C and he provided an honest evaluation on what was needed and not needed to have cool air this summer. Would not hesitate at all with referring Sierra Air & Plumbing for your A/C needs.

Nick was absolutely amazing and my guardian angel! He was able to get my a/c working better, more efficiently and much cooler! Last summer my bills were $500/month at 83° in a 910 sq foot condo. Nick was kind enough to recognize that that is not acceptable, especially for someone with major medical problems like myself. He cleaned the dirty coils which I had previously been told were beyond repair and was able to correct the refrigerant so that my unit not only works more efficiently but much cooler. With his hard work the air was 10° cooler after service than it was before giving me hope that I will have lower energy bills this summer.

Nick was not satisfied with just the bi-annual maintenance that I have had since I bought my condo in 2012. I explained how I had unsuccessfully fought with my home warranty company for over a year to get these simple repairs done and in two hours he resolved what my warranty company refused to do for over a year. But he didn't stop there: he scheduled a courtesy follow-up appointment to ensure that his hard work was successful.

I will ALWAYS call Sierra Air for my heating/cooling needs with no hesitation. And I will always ask for Nick Pope to be the tech who comes out. I owe him a great debt of gratitude for my physical, mental and financial health. I whole-heartedly trust and recommend Sierra Air. They will provide you a valuable service in this crazy hot town with compassion and very reasonable rates.

Three weeks ago I arrived at my Vegas residence and the heater wouldn't turn on. It was 30 degrees outside and 59 degrees inside. I called Sierra and spoke to Michelle who arranged for Emilio to respond. Emilio rapidly diagnosed the issue and got my heater running in no time. Emilio recommended a vent cover to prevent future issues. I signed up for their biannual service and set an appointment for today. I spoke with dispatcher Michelle again who graciously provided me with an afternoon appointment since I was running late. Mind you both occurred on a weekend which is not normally permitted as a routine service call. Dan came out for the service call and installed the vent cover. All three employees Michelle, Emilio and Dan were very polite, professional and considerate of my needs. The technicians were very clean and worked efficiently to get the work done in a timely manor. The prices were very fair for both the emergency call out and routine service. I highly recommend this company for air/heating needs and am especially thankful to have interacted with Michelle Emilio and Dan.

Water heater failed, installed 2010, on July 4th. Jeremy from service came to home to diagnose, and we ordered a new one for installation on July 5th. Jeremy returned on agreed time on July 5th, and installation was prompt, professional, and improved in several ways --new stainless steel connectors, better earthquake arms and support, drain pipe from tray correctly done, all seals done according to code. Only error was billing failed to give me $50 credit for old water heater (as on sticker on old one), and I've contacted them to correct that error on my credit card. Overall, recommended. Update: Contacted quickly by Sierra to fix $50 credit issue. All fixed! Great customer service!! And water heater working perfectly...
