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.

They have been above and beyond in the installation and servicing of my equipment. They are kind, prompt and unbeatable when it comes to customer service. I highly recommend this company.

Great company with great people working for them.
I hired Hobaica to instal a split system and to add a zone to my home.
Everything they said they would do..and more.
I have no hesitation to recommend them.
I have no desire to look elsewhere for a HVAC 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!

When our upstairs AC stopped cooling, we called Comfort Experts.  Ryan was easy to work with, personable, and professional.  He explained to us that our unit was very old & leaking refrigerant, and since the old R-22 units are no longer being manufactured, our best option would be to replace it with a new unit which uses the R-410A refrigerant.  Ryan was patient as we had to reschedule a couple of times (long story, but we were trying to get our home warranty to help cover the cost of a new unit, which didn't really work out).  One thing we liked about Comfort Experts is that they offered to match the price of any competitor who bid lower for the same job.  We will use these guys for all of our future air conditioning needs!

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.

This company superseded my expectations. As a single mom, I am always leery of service companies ripping me off. I never felt that with Reliance. The tech who came out to look at my AC unit never pressured me into buying their unit. He simply stated the facts and let me make up my mind to purchase- which I really appreciated. My rep, Daniel, is fantastic. He took the time to explain everything in detail, to find the best option for me. Enrique and Jose were very polite and quick to get the job done. We had a little glitch in the thermostat. I called Daniel and he immediately took care of the problem, within the hour of me calling him. David followed up with cleaning the air ducts. I am so impressed with the professionalism and top-notch work they did. I would absolutely recommend them to anyone!

Had some opportunities with another A/C contractor, so I returned to yelp to find another. They were very professional, organized, reasonably priced, responsive, and catered to my specific needs. I will use them again.

UPDATE: After this review I received a call from the owner, I am happy to report he did everything to make it right and I am satisfied with the final outcome.

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.

We had a motor which burned out on our furnance (it suppose to snow tonight in Sedona) and needed to be repaired. Once the part was ordered and received, Stay Cool came out and fixed the issue. They even stayed an extra 15 mins or so to explain what fixes/repairs were made and tested the furance to make sure it was working well.
Thank you so much,
Daniel

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!

This review should have been done many years ago but life has a way of getting away from you. In the winter of 2015 I was shopping to replace my HVAC system and gathered quotes from a number of companies. I went with Kevin Konnis at Quantum Climate Control Services based on his competitive price, excellent online reviews and a recommendation from an HVAC wholesaler.

I highly recommend Kevin at Quantum Climate Control Services based on over 7 years of having him not only install a new HVAC system in 2015 but also having him service it. Kevin is professional, knowledgeable, honest and a great person to work with. He's a straight shooter who gives you options with no hard sell. I trust him enough that he has done work for neighbors, family, and friends.

King plumbing gets a very good review from me.  Although I did not hire them for plumbing because I am a very good plumber myself but rather I hired them for air conditioner service.  This technical kind of job out classes my skill set and tools so I needed  some help.  So I Yelped out.  A few out other companies were not willing to service my unit (because it was a Mexican market unit I bought for cheap).  Some other companies were willing but they Didn't have any reviews yet but I wasn't willing to be the first one.  So I called King plumbing because they had very good reviews already.  What can I say the reviews don't lie.  The first company I hired last year to do the install messed up the install.  It was a simple mistake but there was a tiny leak and so the machine ran out of Freon in the winter when I need it to make heat which makes it kind of difficult to service.  King Plumbing Took care of it easily, and they came through right away and fixed it very reasonably.  Their master journey man level technician was very professional and respectful.  I was happy and proud to leave him his first tip.

Very responsive company. Retuned our call promptly and arrived ahead of schedule. Rick was professional and got our unit cooling again within minutes. Will gladly use them again.

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!!!

I am so glad we found Canyon State Air Conditioning, Heating & Plumbing to continue to provide HVAC and Plumbing services for our 89 years old aunt who lives remotely in Sun City from us in CA...My aunt, who lives in an hoarding house, very seldom allows anyone to enter her house for repair, including the telephone and utilities company.  On top, she stays up all night and sleeps at day, having hearing difficulty.

Her AC and heating unit went off in July, we reserved the next day free estimate appointment with all difficulty notes of entering.  Instead of say NO to us like some other companies we called, Kelli Kerber, the dispatcher, patient ally took down all information for us... Jorel Canizales, arrived on schedule, talked to our aunt, gained her confidence, trust and came in with the repair done at no charge to us...NO kidding...he spent times to explain and

We trust Cayon State Air Conditioning that goes beyond and above to serve elderly customers with special needs.  Thank You.
