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.

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!

Steve, our technician, was on time, courteous, and he provided accurate information. He performed his inspection of our two AC units, noting some maintenance issues that need attention. When I told him I wanted to defer fixing these problems for the present time he didn't try to talk me out of it without by overstating the severity or immediacy of the concerns. Hobaica Services has performed fall and spring AC checks for us for many years and they are invariably polite, punctual and professional.

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!

Comfort experts went above and beyond to make sure that we got up and running again quickly. Ryan was great, start to finish. Explained everything thoroughly and handled business! Thanks comfort experts. WE HAVE A NEW HVAC COMPANY!

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

Fabulous service! It was stifling out and temperature was raising in my house - he fixed my A/C in minutes!!!! Thank you so so much!!

Reliance is by far the best in the business. They have been an absolute God-send with so many uncertain times for during the AZ summers. The best guys around....Daniel Grimm is a total blessing to our family. Too many stories of blessings to share. I promise you won't find better service or quality of work anywhere else. Grateful for Reliance!

I had a bad capacitor on a Carrier AC unit.  They did the work without telling me the costs and then handed me a $589 bill.  I was not happy but paid it.  They returned 5 minutes later saying they mis-charged me at it should be $504.  Then returned 5 minutes later saying it should be $462.  I called a friend, asked who they use, Sun Reys AC. I called them with the part that was replaced.  He said part and labor would be $130.  

Even better, after they left, the unit stopped working and they had to return.  Hope they don't tell me I owe them more money...  I won't be using this company any longer.  I understand all companies need to make money but come on, $462 for something that should be under $200.  Not right.  Shame on me, lesson learned.

I had Day & Night do an emergency repair to a water line from the water meter to my home. The staff I spoke with were helpful and pleasant. The technician (Cameron) was friendly, knowledgeable and efficient. They were the only company I called on a Saturday afternoon that was willing to come out and fix the broken main water line within 4 hours. They actually came 2 hours early. I would give them 5 stars for how I was treated and the work done.

I am giving 4 stars due to many of the other comments related to price. I thought $746 was high for 2 hours of labor and minimal material cost, but it was a same day repair request on the weekend. I think most of what homeowners get charged is generally on the high side nowadays. I understand various factors go into pricing and likely many other companies would have charged similarly. I would still use Day & Night again due to their quick and professional service and friendly staff.

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.

They are fabulous and so very knowledgeable.   Came out, gave me an estimate and we set a date and time.  I had to have a complete air/heating system put in.  They came out, did their job which was greater than it should have been but the one that had to be removed was not done as well as it could have been.  Apparently, because of that, they had more work to do.  Never had a complaint, just did what had to be done.  They are a full service company and they will be my go to for all my heating and plumbing needs.  They are as honest as the day is long and besides being very professional,they are very congenial.   I cannot say enough about this guys.  They are terrific.

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!

I had a really expensive quote from another AC company for a massive rip-and-repair of existing ductwork and an old AC unit, so I wanted a second opinion.  Kevin was prompt, professional, and smartly suggested just replacing some crushed ducts to fix the hot rooms before doing anything else.  Doing incremental work to see how much it helps before the massive repairs was appreciated and much more cost effective.  He also took the time to measure the current/power draw on my older AC unit to see how well it is performing to its SEER rating.  Highly recommend Kevin for any HVAC work!

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

Aaron A just repaired our A/C.  It was not an inexpensive fix but he diagnosed the problem quickly, explained it fully, and completed the repair expeditiously leaving us satisfied with the result.

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
