Best Heating & Air Conditioning/HVAC in United States

Jerry the owner is one of the best in this market. He is fast responder, friendly, knowledgeable and fair.. I've lost my roof A/C in the middle of August heat wave of 110-115 temperature. Jerry did diagnose the problem, initiated a plan, got the parts and fixed it. All done fast and professional. High five to you Jerry, please keep up the good work. I highly 100% recommend his company to friends, families and neighbors. Call him if your AC fails, you'll be happy

Derek & his team are very knowable & able to diagnose issues that other HVAC techs have a hard time with. He has worked on several projects for me and has always done a fantastic job. I find Diamond Mechanical to be a very good HVAC contractor and recommend them to all of my clients.

Honest and very professional... Found myself a permanent a/c guy to take care of all my a/c repairs. Bills a/c was more than fair and very good at there trade.  after the other company less than professional services.  Bills is a go to for a/c heating repairs.

I am so happy with the service I received from Sammy at Total Care Heating and Cooling today. We had a torn air duct in our attic and he quickly taped it up and recommended we replace it down the line (which we figured anyway). Instead of trying to upsell me or strongly push replacing it right away, he was honest with me and let me make the decision for myself. We will be calling Sammy again in the future for any other hvac work!

Just now Innovative Air Tech Garrett came to my home and did annual springtime maintenance on my home unit, and on the ductless splitter unit Innovative Air founder & owner Julius installed years ago on my guest house in the back yard.  

Garrett was professional and knowledgeable and completed all the work in this one call.  He made a minor correction that could have been a major problem in the weeks to come.

People like Garrett are the reason I recommend Innovative Air  Conditioning & Heating to colleagues.  Everyone at the company is great too, particularly Karen, who manages the office.  And with preventive maintenance like today I can rest easy for the coming summer

Honest guys. Did all the work, and did not try to sell me things I don't need. Very trust-able people. I am very happy. My AC is running smoothly.

Just our luck, our air went out during the hottest time in Arizona. Our neighbor recommended this business. The owner Jorge came and work on our unit for most of the Saturday afternoon. Though he was not able to fix it with parts he had, he was willing to come back Sunday. As promised, he came early on Sunday and worked all morning to make sure we had air conditioning. Jorge is an honest , reliable and reasonable with pricing.  I cannot rave enough about this business and the owner.  I highly recommend him! He is a savior from the Arizona hot weather!

Honest to a fault great work they had it fixed up and solved in less than 15 minutes will be a repeat customer. So glad to find an honest ac company. They did an awesome job and earned my loyalty!!!

Chase (the owner) is truly a professional.  He responds quickly and gets the job done very well, timely and at a reasonable cost. He has always taken excellent care of our HVAC.  I highly recommend Top Gear to anyone needing scheduled maintenance, repairs, or a new heating and/or cooling unit!

After returning from Vacationing abroad. Came home to 100+ degree weather. Reached out to Alexis at Royalty Air, and to my surprise, set me up with a same day visit to check out my lower floor Ac unit. Unfortunately the compressor did not hold up. (Was an older unit) Alexis ordered me a new one. By the very next day he arrived and set it up. Top notch service all around. I will recommend Royalty Air to my friends and family.

After waiting  3 weeks for One Guard to resolve our AC issue I finally called Emery and could not be more satisfied.  They came out on Wednesday evening, installed the new compressor the next day.  They are highly proficient, expeditious and the customer service is beyond superb.  They will be our new AC contractor as long as we live in Phoenix.  Cudos to Emery

Our A/C Compressor went out. Our home warranty company sent us another vendor. Thy said the compressor was shot but convinced my wife to replace the entire 25 year old unit (outside of the warranty coverage). A few month later the original thermostat needed replacing. The other vendor wanted to charge $225 (even though they should have replaced it as part of replacing the A/C, and even then should not have charged us more than the $75 service charge had we called the warranty plan to do it. So we said no thanks, called the warranty plan, and they assigned Heat Slayer. They accepted that I told them the thermostat needed to be replaced and brought one with them and installed it in 30 minutes (I feared they'd first need the warranty company to approve their assessment, but no, they treated it as a done deal). Heat Slayer was excellent and I'd never hesitate to use them again.

I highly recommend this company. Thad answers the phone and responds immediately. He provides excellent customer service and a very fair price. Our home has two AC units. One broke down last summer and he handled everything within the same day. This year the second one broke down and he handled it just as quickly as last year. He tells you what to expect and sticks to his quotes. You don't get the runaround or told one price and then pay two times more. We love him!

They serviced our air and heating units for a fair price and come highly recommended in the EMR community

Don't hire this company! They only care for money not quality or service. Tried to speak with the owner after the manager told me she had to speak with him to make decisions. Obviously they care little about problem solving

I called them out for my heatpump that was inop. This young guy comes out connects his gages and says my unit is out on low pressure and that
I have a refrigerant leak and he says he can hear it. He then says he can
set up another call for leak testing which cost much more money. So he
charged me $49.95 a service call for nothing. So I called another company for a second opinion the second company came the young man went thru all the proper diagnostics located the problem a fixed it cost $49.95  service call, no leaks no parts! I personally observed both technicians. One was properly trained the other was lost in space. I will never use this company again, I paid for service I got nothing my final rating is 000000000000000000000000000000000000000000000000.
