Best Heating & Air Conditioning/HVAC in United States

Paul was the technician that serviced our A/C for routine maintenance. He was prompt and I also received a courtesy phone call with ETA before he made his way over to our house which I GREATLY appreciated. He was very professional and explained the work he had completed and also the proposed preventative work he recommends we get done to ensure our unit lasts as long as possible before having to replace it. I recommend Northern Air Mechanical Services and will continue to use them for maintenance services and repairs if ever needed.

Robert did an awesome job for a reasonable price. Good attitude, worked super hard, got it done in a timely fashion. Will definitely be using him again for anything we need hvac related. Recommend him highly. He replaced our air handler and condenser and relocated it all in one day.

Very helpful and honest company. They were able to complete the requested work very quickly. I would definitely use them again.

Their technicians serviced my 25+ year old AC unit and repaired some leaky ductwork.  They showed up on time and kept me informed at every phase of the work.  Increased the functionability of my older unit and it was able to keep up with the record heat we are experiencing. Great job!

My husband has been using Hobaica services for 30 years! They have always been honest, courteous, prompt, and fair. We have our units serviced yearly and have never been disappointed. I had two units serviced yesterday. Steve was on time, professional, courteous, thorough and did a great job! He took a video of the units on the roof, which was excellent, so that I could really see and understand what was happening with both units. He serviced both air conditioning units, tuning them up, and cleaning out the coils. Super service. Fair prices. Ease of mind knowing you are working with a well established company:)

My parents purchased a home and needed a new unit and new ductwork. LRG did a fantastic job. The pricing was fair and the work was completed fairly quickly. Very professional. LRG is the way to go!

Received a quote to replace non-working AC unit in warehouse.  Ryan was great, honest, prompt and friendly.  Told us things no other company had like replace with the same manufacturer that the old unit was for the footprint to make it quick, the unit we needed was out of stock so we bumped up to a 16 seer instead of a 14.  Unit was up and running quickly and no problems.  Appreciate it!  Will use again when the need arises

Jake is an outstanding guy! On time, friendly, good service and attention to detail!
Thank you

Danny swiftly responded to my request in getting my hvac system tuned up and repaired because my house was being put up for sale.  An inspection for the house was completed and the hvac system was CLEARED.   Danny was professional, friendly, and approachable.  I will be using this company again.

What an awesome experience!  Called me to tell me they were on their way.  Had a super nice service guy!  He explained everything to me and actually showed me pictures of the problems.  I was shocked at how reasonable they were and how professional.  I had 2 different friends recommend companies to me and after checking their reviews I picked Reliance.  So glad I did!!

We highly recommend Accutemp.  We had a couple of service calls on our old heat pump which were very satisfactory.  When the heat pump died, we bought a new system from them, and installation and a couple of maintenance service calls since have been excellent.

But, we would not buy a Carrier Heat Pump again.  Works fine, but the programmable thermostat is just too complex, and difficult to understand and program.  And the system won't accept non-Carrier replacement thermostats.

Great service.
I needed a new thermostat installed. I was able to get same day service, exactly on time, and the technician was thorough, polite, and showed me everything I need to know.
The price was great too.
I'm really thankful for the help.
Rene was great!

Both of our AC units were on their last leg, house is about 20yrs old. I got quotes from 5 different companies, many of which were much larger, lots of the larger ones sent out dedicated sales people which was kind of a red flag for me that they need to charge higher prices for all of their extra employees. I'm really glad that I found DeModica Air, Jon Jon came out the day after I called him, explained all of my options, including patching my existing units which he said he could get them to last probably another 3 years. But he recommended replacement and we are glad we went with his recommendation. He had both units replaced, along with the air handlers in just 2 days. I highly recommend giving them a shot, at least invite them to give you a quote.

A less than four year old condenser unit would not start up. Called Stay Cool and had an appointment window for 2-5 PM. At four pm i called to confirm and they said yes, but someone else was in front of me. 5:30 PM rolled around and no Stay Cool. No call, no nothing. Unreliable, unprofessional. Buyer beware.

Last month our a/c stopped working. We filed a claim with our home warranty company on a Saturday and I was so worried that we were going to be without a/c for several days. Being August, 8 months pregnant, and also having a 1 year old I was very concerned! My husband left a message on Sunday, and someone contacted him back letting him know they would be out early Monday. The communication was great and the tech who came had the part we needed on hand and fixed it right away. I was so thankful! Great customer service and no further problems, couldn't ask for better!

Kevin did a fantastic job installing a complete new air-conditioning system for me in the middle of summer in fact on the Fourth of July holiday  2015.
I was fortunate enough to have a good friend that I've been swimming with for seven years and her husband is pretty good at fixing things but he took a look at my air conditioning and said you need my guy to take a look at this and see what needs to be done. He sent over Kevin who took a quick look and said that my compressor was broken. He said other than that and the air-conditioner was in good shape and was actually only 10 years old which apparently is a baby in Arizona.
I asked Kevin how much it would cost to replace the compressor and give my system  a good service. Kevin said it would be $2000. It would be more expensive because I had been running the AC thinking if I ran it, somehow it might magically repair itself. Then I asked Kevin how much it would be  to get a fuel-efficient up-to-date modern new air-conditioner.
Kevin informed me that he could put in a complete new system that would run economically and be eco-friendly for around 4 1/2 thousand dollars. That price would include all his labor.
No-brainer of course I would go for a complete new system it seemed incredibly reasonable.
And also informed me that by 2020 all systems would have to be compliant and my system used Freon and new systems in 2020 would no longer be using Freon although if they were an old system and you had a stockpile of Freon you could use it.
I care a lot about the environment and in all cases I prefer to use environmentally sound products.
Kevin had to special order my new AC unit and in the meantime I purchased a freestanding unit and spent the next few days in my bedroom trying to stay cool.
Once my new unit arrived Kevin worked extremely hard to install the new system starting first thing in the morning and working outside and tremendous heat until it was dark.
Took Kevin to full days to install the new system but once it was up and running and it was an incredibly smooth and quiet system and I was amazed at how efficient it was.
I have always been economical and using my air conditioning since I live alone in a house that is two stories.
I had my way I would have individual unit air conditioning her room as I think central air-conditioning is such a waste for a single person living alone. Sadly the homeowners association will not allow us to have individual units as they say it is unattractive to have units showing in the windows it's perfectly ridiculous.
So I have to cool my entire house which to me seems great waste of resources in these days when we are wasting precious energy and polluting our environment.
However my new air-conditioning system is so efficient and powerful that within an hour of turning it on my house seems very cool where is the older system would take 4 to 5 hours to cool down the house.
Send noticed that my electricity bills are much lower now with this efficient new system
I would highly recommend Kevin to anyone who is looking for an honest hard-working and very pleasant man who really knows what he is talking about as far as all aspects of air conditioning are concerned.
Kevin  is hard-working and diligent and will give you an extremely valuable and efficient service.
When I turned on my air conditioning for the first time this year it came on and was very smooth and cool. I did have one blimp when somehow the air handler got flipped off and I had not realized it but Kevin came over at the drop of a hat and switch the switch back on and everything is running smoothly  again.

The guys at King AC and Plumbing are the best. They saved me thousands of dollars. I first had my AC unit looked at by one of the big AC companies here in the valley because it was vibrating very badly. I wont name names, but let's just say the original owner's last name is the same as a large South American country where the World Cup is taking place right now. After the big guy's service tech failed attempts to convince me that I needed a brand new unit ($5,000), he told me that the blower motor needed to be replaced and would cost $1,300 with some sort of VIP package. A few days later I saw Brendon with King AC in my neighborhood working on my neighbors unit. It was already pretty late in the evening, but after a quick conversation with Brendon, he gladly climbed on to my roof to take a look at my unit. He came down and said there was an issue with the blower motor but it would be nowhere near the $1,300 I was originally quoted. He also informed me that the other guy that came out never even opened a single panel on my unit to come up with his expert diagnosis. The next day I received a call from the owner Terry who told me that the motor was a specialty order part and was quite expensive, but again nowhere near the original amount I was quoted. He also informed me that most likely the motor didn't need to be replaced, but the squirrel cage probably just needed to be cleaned out so it could spin properly. With Terry's advice in hand, I spent a couple of hours that weekend cleaning out the very dirty squirrel cage which was super easy to do and cost me $5 worth of cleaning solution. After I put a couple of panels back on and started up my unit again, the heavy vibration had completely disappeared. Today I had Brendon come out to take a second look over my work and make sure everything else was tip-top. He informed me that my unit needed a couple pounds of Freon and everything else with my dinosaur of a AC unit looked great. Now my unit blows colder than ever and stays on half the time that it used to, which is going to save me a small fortune on my electric bill. I have nothing but compliments for this company and their employees. All around knowledgeable and honest guys. I will never call another company for any of my AC or plumbing needs. I know with King I will receive an truthful recommendation at a good price. No scare tactics, up-selling, or commission based sales. The world needs more genuine people out there who work to help others and not take advantage of them. Thanks King AC!

Very disappointed!  First off, I know a lot about this stuff and can do most of these repairs myself.  Since I now have a bad back, I have had these guys out 3 times over the last couple of years.  The first time I had their $159.00 service and I told the technician to only put in the 1 pound of  freon that was included in the service.  He comes down off the roof and tell me he put in 2 pounds and charges me an extra $100!  

When my AC stopped cooling last year I figured I would give them another chance.  I had them out and they said I needed 2 capacitors.  It killed me to have to pay $350 for 2 capacitors that I can get at the appliance parts store for under $50 but I had them do it.  They said they would throw in an extra tune up the next year so I figured that would save me some.  

This year came and when I called to get that tune up, they said it would only be a free service inspection, not a tune up!  I would never have paid for the repair last year knowing this.  I would have done it myself and saved $300.00!  Very shady and not cool at all!!! (Pardon the Pun).  Won't be using them again and don't recommend them to others.

I have a fairly new home, built less than 2 years ago, and my tankless water heater went out a few weeks ago. The company charged me for a part I didn't need that was still under warranty. It took two weeks for them to finally fix it and all it needed was an electronic master reset.

I reached out to ask about why they charged me for a part I didn't need and they said due to all the time they spent here and on the phone with tech support.

Here's the issue I hope you correct going forward so it doesn't impact future customers:

1) Your technician didn't spend more than 5 minutes here the first time. He didn't troubleshoot anything. I told him the code and what I looked up online that led me to calling you. He said yup that's it. Then he left.

2) Had he troubleshot the issue it could've been resolved that day and we wouldn't have been without hot water for two weeks. Also, this would've prevented the ordering of a part that was unnecessary.

3) The second technician said he's not a plumber, rather he's an HVAC guy. I think having the properly trained technician would have sped up the job, reducing time wasted on troubleshooting a master reset.

I am giving 2 stars instead of 1 because  I am thankful the last technician that came out was honest and was able to resolve it and get the water heater working.

I would definitely NOT recommend this company.
Called to have my 3 units looked at and was having issues with one.
Said he could only look at one unit and not repair it. Said he was slammed today.  How would he know if it would be a quick repair or not? First of all, why would you not repair it ? Isn't that the point of calling a repair company?
Called the office to explain that when I scheduled I asked all units to be checked out and rearranged my schedule for them to come out. Finally, she said that he could check all the units and insisted no repairs would be made. Again, why are they insistent on no repairs? That is the whole point. It is $75 for the service call but they plan to leave you hanging.
When he checks the unit I was having problems with, he came in with a list of several things that were wrong with the unit which would cost $4500+ to repair but he wouldn't recommend the repairs because it's too old of a unit. Was told I need to get a new unit which they send a sales consultant to go through the various types $4K-$20K.
I decided to do a little research and ask around for another company since obviously this wasn't going well.
My son's friend's dad has an A/C company and he came over early today (Saturday morning), investigated the problem, went over with me the cost of replacement parts which were strictly a maintenance issue. It is a Trane unit which is one of the best so maintenance is all it needed. He went to pick up the parts since Saturday they are open until noon. Came back, replaced the parts, checked the freon and it didn't even need any and it instantly became cool. Parts are warrantied for 5 years so at that time, if they are problems, look at replacing it then.
$1500 and I am set for 5 years!

You have to give Arizona Acclimated Air Conditioning & Heating Services a call: 602-616-8044
They have an A+ rating with the Better Business Bureau. I'm not surprised!

Back to this terrible company. Every single thing he said was not working was FALSE. He also told me it needed 11 pounds of freon at $200+ per pound so $2200 in freon alone. There were no leaks as he claimed. If I had no freon and did not get freon today, why is my house so cold now?
They push hard on new units so that's their scam. They don't want to repair anything for you. They want to rip you off!
I have to get up now. It's so cold in here I have to turn up the thermostat.
