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.

Had a wonder experience! Thank you Phil Kneisel for taking your time to better explain the science behind runniing your air more effeciently in this desert heat!!

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!

Thank you

I got home from work and noticed that my thermostat wasn't on and I did some troubleshooting.  Found that a fuse was out.  I called around and everyone was too busy to stop by.  Danny came over right away and replaced my fuses to get my house warm again.  He noticed that my fan wasn't working correctly and he was able to replace the parts the next day.  I was impressed with his quality of work and his willingness to go the extra mile.  

If you are stuck in the cold and need your furnace fixed right away Danny is the guy.

I was in a bind since my AC took a crap. Got 3 estimates and didn't want to wait any longer because it was getting hot soon. Reliance had estimator Daniel come out same day with in the hour with his trainee. Took photos of everything and showed me with detail description what they will need to do. They didn't push me into buying the expensive units, just explaining the difference of all the Tranes they carried. The other estimates was Ruud and Goodman, very basic, and cost more. The other companies steered me away from Trane cause they said it's hard to get replacement parts. Daniel assured me he has warehouse stocked with replacement parts. 2 days later the crew arrived around 7:15 and finished by 2:30. They did a great job with install, clean up and orientation. Thank you Dalen and Michelle for taking care of me :)

I used Accutemp in 2013 and received good service. No idea what happened to them, but they failed miserably this last time on an unnecessary level.

I called Accutemp on a Friday and made an appointment for the following Tuesday. They gave me a 4 hour window for the appointment (1pm to 5pm). While I was a little unhappy about the large window, what could I do? I waited all day and even called off work to make this appointment happen. As you'd have it, it was 4:50pm and they called and said we won't make it, can we extend the window an additional 2 hours? No thanks.

While I understand that things happen it is paramount to communicate to your customers. With a 4 hour window you never thought to call me and let me know that you may not be able to make the original window?

This may be one of those times where Accutemp should have under-promised and over-delivered. Instead they under-promised and under-delivered. Instead I went with Dukes of Air and my experience was completely different - they were in contact with me 3+ times before my appointment AND ended up coming over 2 hours early.

Day & Night were fantastic. Ron called on his way over, he was super friendly, he tolerated my dozens of questions, fixed my furnace, and helped me upgrade my thermostat. Hire this man. Ask him questions. He is a wealth of knowledge about HVAC. This place is 24 hours and rock solid. Super trustworthy.

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!

We got an awesome heat pump installed and couldn't be happier. Our Bosch unit was installed  and purrs like a kitten. We also got some advice to get some roof repairs done, to correct  some problems created by our former HVAC unit installation.
Kevin did the work himself, after the roofers performed repairs. We are very happy with our choice and want to highly recommend Keven to anyone who reads this review. I will hire him again in the future and I will tell all of my family and friends how happy I am.
Sincerely, Iris.

I had them move my washer and dryer hookups from the kitchen pantry to the garage. Their rates were fantastic, I did get multiple quotes, and the tech was very knowledgeable. They were able to schedule quickly and paying the invoice via apple pay was very convenient. I am very pleased with their service and quality of work. They'll definitely be the first call for future plumbing issues.

Won't be using their business since they failed right from the start!

Called and Made my appointment for a new installation for a 3-4 ton unit I was looking at. Gave them all my info that was needed for contacting me since the appointment was at 1300-1600 they said they'd call 30min prior to showing up. I informed them that I just purchased this property and that we would be doing renovations before moving in so make sure you call.!

Get off work early to make sure I'm there by 1 in case they came early..started doing some renovating while I waited. 3.5 hours go by and still nothing, so I figured I'd call and touch base. Come to find out they decided to change the appointment to early this morning without my knowledge or approval. Not only did they not call but they took it on themselves to deem the house empty and do absolutely nothing. Doesn't seem so honorable, reliable, accurate or precise as they say.  As a veteran I take that personally because those are things I live by and being a man of your word goes a long way.

Looks like I'll be taking my business and some others with me.

I was having a tough time finding someone to fix my Midea Air-handler, as it is not a common brand of A/C.  When I called 1800Plumber+Air, Ben answered the phone and listened to exactly what the issue was- he took down the model of my unit and actually talked through the repairs with his tech before sending him out.  The other companies I called (Goettl and George Brazil)just have an answering service and they do not relay any important info to their techs, thus having them show up only to say they could not fix it or find parts.  
Ben listened to my issues and the awful experiences i had at the other places and said he would take care of it for me and that the tech he was sending, Travis - was the best.  Travis showed up and quickly fixed my A/C (needed a new control board) and only charged me half of what the others said a new board would cost if they could find one to fit my unit.  I will never call anyone else again but these guys for plumbing and A/C!!!

Our heater went out so we called Canyon State. We got a quick fix but unit was 13 years old and needed more work done to function correctly. Michael came out next day to explain fixing or replacing. We opted to replace since unit was so old and not that efficient any longer. Two days later Manny and Steven came and installed the new unit. Very professional men and it was done in no time. BOY what a difference the new unit makes. Also want to state that lady that took the original call was very caring and listened to our problem then referred us to the proper person for a solution. All aspects of our transaction with Canyon State were  5 star
