Best Heating & Air Conditioning/HVAC in United States

Sold our house, and the buyers inspection revealed a couple of issues we didn't know about. A/C drip pan in the attic rusty, and drain line possibly plugged.
Since I had such a good experience with this company a couple of years ago, gave them a call.
Efficiently scheduled appointment. Technician showed up on time. Thoroughly professional gent fixed the problems for the price I was originally quoted. I highly recommend this Company. Their standards and behavior have been exceptional!

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.

Another 5 star rating for Hobaica company and its excellent technicians,
Today one of my two units went out (on a Sunday) and I called the weekend service number and a technician,  Ron J. called back within a short time and
said he would be out within a half hour.. Ron arrived, quickly solved the problem and was on his way.....Ron had been out before on previous calls in the past few years,  and he is an outstanding  service man....I wish I could give him more than a 5 star rating..

My family and I have been with Hobaica since  they first started in business in the 1970's. We ALL use Hobaica and wouldn't trust our A/C ( and now plumbing) to any other company.
Thank you  Hobaica for  almost 50 years of great service.

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!

AC let go mid-day yesterday. The wife and I set up a wind tunnel in the Livingroom to make it through the night. 1st thing this morning, hopped onto Yelp and found Comfort Experts and had Ryan come out a few hours later. Within an hour he had us back up and running :)

Life savers. Thanks Ryan and Thanks Comfort Experts for being on point.

Very much appreciated

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.

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!

DO NOT USE THIS COMPANY!!! I  am a landlord and unfortunatley currently out of town and this company totally tried taking advantage of the siutuation! My  AC unit was acting up in 110degree temp and they sent a tech out who totally misquted and later to find out mis diagnosed.  For what they needed to replace they qouted me $1700. I thought this was high so I called 2 other companies through Yelp and the 2 other companies qouted me $1010 and $990. Then when I declined to use them and I told them exactly why, she charged me $195 for 3hrs of examination when it probably took 1hr and that was to call around for parts.  I will never use this company agaion and totally advise anyone to stay away!

Kevin at Day and Night AC provided excellent service today when he came for our AC service.  He identified some subpar work and short cuts another contractor had used on our unit a few months back that we were unaware of.  We were able to contact the other company to rectify their mistakes.  Thank you for your honesty and diligence Kevin!

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!

Quantum is by far the best AC Contractor I have ever used. I called for service around 8:00AM and Kevin was at my house a few hours later to look over my system. He was very honest and did not try and sell me anything that was not needed. He had my system up and working in a few minutes and his price was fair.

I had Brandon from King come out to give an estimate for a waterline to the refrigerator and for my dishwasher. He was completely progressional in appearance (that matters to me) and manner. So impressed I called them back the next day to the job. The day before he showed up we had our AC quit working, he was nice enough to take a look at it and even figured out the problem right away, so my wife and newborn could get some cold AC. I am very impressed and will call them anytime I have any issues.

I have used Precision 2 years in a row now.  My Technician Aaron was very thorough, personable and patient with all of my questions.  One of my questions required the sq footage of the house and he actually took a measuring tape out and measured the house to make sure he answered my questions with correct information. He then sat down and took the time to answer all of my additional questions.  I have had no issues with precision and will continue to use them for all Future Maint needs.  Thanks Aaron and Precision

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!!!

Last Thursday at around 4:30pm when my wife got home she realized our upstairs AC wasn't blowing cold air.
We discussed for a moment waiting till I got home to take a look at it (since I do many of our home repairs myself) but quickly concluded that we should get a technician out to our house ASAP or we'd likely need to wait till the next morning.  My wife called Canyon State a few minutes after I got off of the phone with her (maybe 4:45pm) and was pleased to learn that a technician would be out to our house (we live in Surprise) between 5 and 7 pm.

Astonishingly, the technician (Jake) knocked on the door shortly after 5pm!

He quickly determined that the problem was with the outdoor unit corresponding with the upstairs AC (a motor had failed, and the unit was evidently SUPER hot)

We approved the replacement for that motor, and by 6:10pm I was paying the bill for the completed repair (using a slick iPad app - which wasn't really a factor, but was cool to see how they were using modern technology to make transactions easier).

We had a cool upstairs by bedtime, and I couldn't be happier with how everything went.

If anything breaks again, I'll definitely be calling Canyon State (saved them to my phone as a contact :)
