Best Heating & Air Conditioning/HVAC in United States

Needed a new A/C unit installed because dog had been urinating on the previous outdoor system. Spoke with Jason who was able to get me a reasonable quote for a new unit installed. They were very patient and listened to my concerns as I had just been ripped off by a different competing place who had been out three times including charging us for coolant when it was spot on obvious there was corrosion and a leak (I do not recommend Simply The Best).

Jason provided the quote and the install was done within a few days which is excellent response time considering I was in a jam and summer is here. Installers were very professional and even had the job done under the quoted time frame and did preventative maintenance on the other existing unit. Recommended. Straight forward, friendly and professional and don't play games with you like some of the other guys. We need integrity living in Arizona with the heat and I can say based on my experience, Northern Air provides exactly that! Thanks again and will use in the future for all cooling and heating needs!

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.

We thought there was something wrong with our AC, but they came out and checked it for quite a while actually. Our AC units were fine and they didn't charge us a thing. And this was during the high heat of the summer!

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!

You can't go wrong choosing Comfort Experts for your HVAC needs. I found this company using a random Google search and boy am I happy that I did.

I HIGHLY recommend Comfort Experts for all HVAC needs.

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

Called them last year to fix my AC.  He thought he found the leak and recharged my system.  Well, the technician did not find the real leak so this year when I turned on my AC it was blowing hot air.  They came out and inspected the system at no charge.  He found the real leak this time.  But stated he did not have the skills required to fix the leak.  The leak was at a Al and Cu joint.   So will be calling another HVAC company.  He did recharge the system again for free.

I would highly recommend Reliance to service your AC. They were quick to respond to my quote request with no added gimmicks. Sean the technician knew his stuff and was very respectful. He wore shoe covers when walking in the house which my wife liked. Also they don't ask you for any reviews or surveys like the cable guy hence why I wrote this review.

One of my A/C units went out on one of the hottest days in the valley...120 degrees today! I found AccuTemp on Yelp and decided to give them a call. They have emergency service on the weekends and while you pay extra for the emergency service, it's worth it when you need them at the last minute on a Saturday. The customer service was amazing. She made sure to let me know the costs and while they were super busy today (not surprising with this heat), she said she would keep me up to date if they could get out to me. She called me twice just to update me on the status and they were out to my house much faster than I ever expected! The tech walked in and got straight to work. He didn't waste any time and had the unit fixed in minutes. (It was a capacitor) The price was very reasonable and he didn't try to sell me anything I didn't need. I would highly recommend AccuTemp and while I hope I don't need A/C service anytime soon, they will be the ones I call if I do. A+

Run, don't walk from this company. My tankless water heater was not working well after 11 yrs. Day & Night bought the account list from Stampede plumbing. The first thing they did was bash Stampede which was a top notch company. Then they quote me $6,400. to replace my unit. He tells me he can flush my unit for $200. (he said the chemicals cost $150). After he left, I flushed the unit, the chemicals cost $10. A friend of mine who is a licensed plumber, bought the unit & installed it for $1800. total.
Day & Night are thieves & liars, run don't walk from them.

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.

Garrett with Stay Cool just showed up an hour early and fixed our heat pump that had been out since last Friday. You don't realize how amazing AC is until it goes out! I highly recommend Garrett and this business!

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 was an amazing contractor to work with! I had 2 heat pumps installed outside, 2 air handlers installed inside, and a brand new wifi thermostat over two years, all through Kevin at Quantum Climate Control.  I did the upstairs unit one summer and the downstairs unit the next summer.  Kevin gave me multiple options, explained the pros and cons of all and then let me decide.  Low key, no pressure, and he never once tried to change the pricing or nickel and dime me.  He submitted the warranties for me, emailed me copies of them, etc.  He did every single thing he said that he would and always showed up on time.  Undoubtedly, the best contractor I have hired.

Kevin actually saved me from certain disaster.  I had some cold and damp tiles on my bathroom floor and I assumed it was a leak under the floor.  I had a plumber come out and he gave me two options, tear up the floor to fix the leak or cut through tons of drywall to run new pipes.  This was right about the time I was considering my downstairs unit so I called Kevin to tell him I had to cancel the unit because I had some major expense in the works to fix a leak in my bathroom.  Kevin advised me that the plumbers assessment didn't sound right so he came out and took a look.  Turns out my old heat pump had developed a Freon leak which was causing my lines to freeze over.  He did some troubleshooting and was able to confirm the Freon leak was the cause of the damp, cold feeling on my bathroom tiles.  With that said, I moved forward with replacing the unit and it fixed the problem.  I can't even imagine if I had ripped up my bathroom chasing some phantom leak!!  That was just crazy, lucky timing for me.  So glad Kevin knows what he is doing!

There are tons of A/C contractors here in AZ but I truly believe Kevin is one of the most straight forward you will find.

Had a new AC installed w King Plumbing. Great price, service and transaction. I would recommend.

We bought a very expensive new A/C unit from them and have had nothing but problems.  We even purchased a maintenance plan with them and had the unit tuned up every year.  In three years the unit has broke four times in the middle of summer, leaving us and our young children sweating all night long.  Even though the unit is under warranty and we purchased a maintenance plan, we have had to pay a visit fee every time they came out to look at the unit. All this while our other 17 year old, builders grade A/C unit has not had one problem.  This new unit was supposed to be rated at 16 SEER, yet our electric bills continue to increase every year, everything else unchanged. We will definately look elsewhere when we have to replace our other unit.

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.

Many thanks to Eric for a prompt same-day response that got my heat working again after it suddenly went out on one of the first really cold days in December--great service for a fair price.
