Best Heating & Air Conditioning/HVAC in United States

Excellent service. Went to great lengths to solve a pesky problem and make things right. Always professional.

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.

Just new in Wickenberg and bought a condo.  Within 5 days the old air conditioner dies and who do I call?  I go onto a HVAC website and ask for suggestions.  Immediately I am contacted by Jason and he asks if he can help.
Besides coming to see if the unit can be fixed, he has Lola bring a temporary unit to get us by until we have permanent air conditioning.
Can you ask for better service?
The next day, at reasonable pricing, we are back up and running.  We chose to go with a whole new unit to replace the 30 year old unit.  Mitsubishi non-duct.  What a beautiful unit and installed by very friendly, professionals.
I would recommend them to anyone.

Hobaica replaced our HVAC 4 years ago. That's when they started down the 5 star path and stayed there. They have come out a few times. That's when we met Binh. He was just here to work on the system and I figured I would provide this review. We have absolutely no reason to call anyone else but Hobaica and always ask for Binh!

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!

Recently my AC broke and I needed to find a reputable company to repair it quickly. Looking on yelp and finding that Comfort Experts had good reviews, I requested a service quote. They got back with me immediately, and were at my house first thing the next morning.
They were efficient, kind, courteous and when they had to return through no fault of their own, they made me feel like I was a priority.
I would recommend them to anyone, family and friends, and I plan on using them when I need to service my AC unit again.
5 stars

Update: Our old unit finally gave out and we called Comfort Experts right away. They came out, gave us a reasonable quote and installed the new unit within two days.
Again, we will only give our business to them! Thanks!

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

Danny C got back to me and scheduled my appt. right on time. Tech Jelani was thorough and had the parts on hand, did the repairs and was fair and provided pictures of worn parts and service completed. We were satisfied with the courteous service and good work! Send me some business cards Danny our neighbors are always looking for honest dependable companies like yours!

Reliance is by far the best in the business. They have been an absolute God-send with so many uncertain times for during the AZ summers. The best guys around....Daniel Grimm is a total blessing to our family. Too many stories of blessings to share. I promise you won't find better service or quality of work anywhere else. Grateful for Reliance!

Our air conditioner conked out in the middle of last night.  I called the 24 hour number for Accu Temp - actually found this company on Yelp and liked the positive reviews.  Within 2 hours of my initial contact, Mike W. came out, figured out the problem, left to get a new pump, installed it and evaluated the system for any additional issues.  
He was extremely helpful and professional.  I am very pleased to recommend this company to fellow homeowners in the valley.  It's nice to know that when the temperatures are in that July August range, this company goes above and beyond to get your home livable in  such a timely manner.

Be very careful using this company.. They eather have employes that dont know what their doing , or they are flat out  wanting to rip  you off.
The reason i say this is as fallows
I called them based on the yelp sight having pretty good stars, but i should have had another person herewith me..

I told the girl i had a vibrateing sound coming from my one wall..
I told the girl i have done a couple of repairs to my 12 yr old unit with in the last two years.i also told the repair man RON that also..He told me the girl wrote that after 2 hours i started to hear the noise.. bad commuication from the start.
thnk god i record all my calls and people that come into my home or i would have not had proof of his manipulation an severe scare tactic to make me pay 1400 to do a repair that DID NOT need to be done because i already had replaced that a few years ago .. yes i know things can happen but this was flat out LYE. I did also have RON talk to my boyfriend on the phone before he went up there and he told him IM NOT AN AC GUY BUT IT SOUND LIKE A FAN IS LOOSE.. MY boyfriend said that/
so instead of RON checking out my whole unit he just assumed that it was a indoor blower wheel going bad and of course i would have to replace the motor too. well I have M S and told Ron i have a medical
condtiton and that i really needed him to turn the unit back on and to my suprise HERES THE SCARE TACTIC.. he said no he could not do that that my barrrings in the motor would cause terrible damamge to my unit. that could be possible if that is what really was the issue
so i got very anixious and afraid and had to call my freind to tell him to
put it on again for me... not to change anything and I would take the responciblity if something happened i wanted a second option. and thank goodness i did..It ended up just being a bit loose, and my compresser needed new stablizer mounts on the bottm to stop the rattle which they didnt charge me for just for the visit.. and i asked them to take photos of the inside of everything which they did.. the other comany stated that my unit looks great and is in good running order.
In my option if a man RON has 25 years doing this and 15yrs with the company they would be aware of his tricks. and another very annouwing thing he would say i counted over 7 time he would say in my Professional Option. REALLY.. He basically would have charged me money and possible done a bate and switch .. i will be contacting the bbb and requesting my visit money..

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!

We were referred to Kevin through a friend that had recently used Quantum. He didn't disappoint! He took the time to go through all of our new AC unit options as well as the current available SRP rebates. His crew was on time and finished the job early. Kevin then took the time to walk us through how the new unit worked, the thermostat settings and how to apply for the rebate. Finding businesses that value their clients is unfortunately becoming more rare. I was blown away when I received a package in the mail from Kevin with all the rebate docs, envelopes prepared for mailing etc. He made the whole purchase process very easy and went the extra mile. in addition, he followed up a week after install to ensure everything was functioning properly and to answer any questions. I would definitely recommend Kevin with Quantum and I don't say that lightly.

Had our backyard sump pump fail (kept tripping the GFCI). Called King Plumbing, Heating and AC and Ulises came out fast to give me an estimate on the repairs/replacement. He was very courteous and offered suggestions etc on how to remedy the situation. After all the parts came in Ulises came out again to do the repairs/replacement of the sump pump and I was amazed by the attention to detail and cleanliness. He kept me informed during the repair process and let me know tips on future maintenance of the sump pump in order to increase longevity.

Once the job was done, Ulises cleaned up and verified the sump pump performance to my satisfaction.

Overall, I would not hesitate to reach out to Ulises and King Plumbing, Heating and AC again in the future.

Thanks Ulises! You rock!

I had worked satisfactorily with Precision Air until they called me relentlessly in Feb 2016. I told them to stop calling and I would schedule in May.  When they didn't stop calling, I called another AC company who came out and found that the new Goodman Air Conditioner put in in Jan 2015 was not working at all..no freon and a part inside had been welded improperly. I was not going to call them back!

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.

Our house was 100 degrees inside because our air conditioning broke in the Phoenix summer. We have a home warranty company but because they couldn't get anyone to us right away they allowed us to call an out of network contractor. We chose Canyon State after the positive reviews. When I call I explained that we could pay up front costs and seek reimbursement from the warranty company later BUT the technician would need to speak with our warranty company to have the repairs authorized. They said ok
The technician arrived and it was suddenly a different story. The technician was there to collect his service fee but refused to talk to the warranty company. The technician left us with a non working air conditioning and a 100 degree house because they refused to get authorization from our warranty company.
So disappointed with Canyon State and clearly they don't care about ac repair at all...just collecting a service fee
I would not recommend Canyon State to my worst enemy. They come for their service fee but don't want to get authorization from the warranty company to do the actual repair.
