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.

My HVAC broke down end of August, Heat warning in effect and literally 2 hours after I called McMillin Air their technician Lalo had my A/C up and running again!!! I can't begin to tell you how impressed and grateful I am! They will have all of my future business. A million thanks is not enough.

Ron Johnson, their service tech, is terrific! We had our floral cooler go out  this afternoon and we called Hobaica immediately.  It only took a couple of hours and Ron came to our shop, and he worked very diligently to fix the old lady. Sure enough after a few hours, she was purring like a kitten. No matter that it was a Friday afternoon/evening. No matter that he had to climb up on top of the cooler and take the compressor apart, in an area that was about 3 x 3.  Hobaica is definitely the #1 air conditioning company to use in the valley.

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!

Love this company and their excellent customer service.  I called at 11am and Dakota was at my house by 1pm.  The best AC company we have found in the state.  Also, Ryan, the owner, is always willing to discuss all your options.

I am so happy and very satisfied with the service of Jake C. and his brother Finley of Transcend Air heating and cooling.
He came in a same day I called him,
he's very knowledgeable and told me about the cause of the issue and what to do and don't.
I will definitely recommend him and transcend to family and friends. I appreciate you Jake C.

Please give them a call.

Hands down the best service ever!! I have a Esthetics business located inside A-Z Chiropractic in midtown Sacramento and our heater went out at the worst possible time! We have many older clients/patients and our older brick building was SO cold and uncomfortable for the type of business so we needed it fixed fast!
We initially made a appointment with a company that couldn't make it out for over 5 days, I am  so glad I decided to call Danny instead because he came out quick and had the problem fixed in no time. Awesome service Highly recommend!!

After getting a couple of estimates I decided to go with Reliance and I'm very happy I did!!  Their price was the best. They were super nice, efficient, and installed my new unit quickly.
I highly recommend them!

Our AC went out this afternoon around 12:30pm, and within 30 minutes we had a technician out to do the repairs. We are SO THANKFUL for their prompt service! Summer in Arizona without cool air is absolutely unbearable!

Our technician, Brian, was awesome (seriously though, give this guy a raise... he's incredible)! He was extremely efficient, very knowledgable, and a sincerely genuine guy. Our repairs were taken care of immediately, and the prices are absolutely amazing for the great service that they provide.

We immediately told our family down the street about this company following their repairs, as they were looking for a reliable AC repairman as well.

I would recommend them to anyone! THANK YOU, AccuTemp!! We are grateful and loyal customers for life!!!

As good as they get. They refused our money until not just done but proved to perform. We are very happy. Friendly and professional. We are out of town land lords which makes us extra worried of being taken.
Thank you.

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 is very personable and thorough with his work.  He showed up on time, and he backs up his work 100%.  His charges are very reasonable.  It's really nice to find an honest, friendly person to do our A/C maintenance and repair!

I used Terry from King Plumbing, Heating and AC about 6 months after we bought our house. We needed service done on our heater, AC unit, and garbage disposal. Terry went right to work, got everything done in a few hours, including installing a programmable thermostat. He helped us get full use out of our home warranty plan and cleaned up after everything was done. Highly Recommended!

My technician was Paul (301286).  He has come out to my house several times before.  He is always courteous and thorough.  I have used Precision Air and Heating and Pipe Tech Plumbing for the past 12 years.  They have come promptly when I needed them.  Even when I lived in a remote area they provided excellent service.  I highly recommend this company.

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.

Jay from Canyon State did an excellent job! He explained the options to fix the problem and did exactly what he said he would do and it was a bit cheaper than he estimated! Definitely recommend Canyon State for your plumbing needs!
