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.

I have worked with Bill and Todd for several years now. They have always been incredibly reliable, fast, friendly, and fair! AC issues are never fun but having someone I can trust to take care of the issues is a huge relief. I highly recommend this company!!

Total Care heating and cooling a great company to do business with. Sammy was reliable, honest, knowledgeable, and well prepared. His prices are fair. He will be are heating and cooling guy for all future needs. Thanks Sammy.

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

Needed a repair on our AC unit, which was still under warranty.  Another AC repair service insisted the manufacturer would not cover the cost of parts. Brett went out of his way to look for a supplier who WOULD cover the part (over$600) under the warranty and saved us that part of the repair.

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!

Condescending and rude. Wouldn't listen long enough to understand what is going on, before telling us what he thinks we are doing wrong, so they never fixed the real problem. I will never call them again.

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

Had great service from Heat Slayer last month. We had purchased a home warranty when we bought the house    and our a/c started acting up. The warranty company assigned Heat Slayer to repair it.
He was very prompt, kept us informed on repairs etc;
We had him work up an estimate for some duct work for the back bedrooms which turned out better than expected and at a very reasonable cost, he also serviced all of the HVAC system.
We will definitely use him for our annual maintenance

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!

AirNow has replaced three AC units for me in the last two years. They have been consistently great to work with each time. When I had an issue that required follow up they were immediate to respond. The technicians are friendly, professional and always on time. I would not hesitate to recommend AirNow to anyone that needs HVAC service or replacement.

When our A/C went out we called cool breeze.They were in the contractors book at the Sun Lakes office where we live. They said our furnace was bad, but to replace it we would have to replace heat pumps out back also. We agreed on a price for a Trane 14seer unit. We gave them $4,000.00 up front. When the Trane unit arrived  it wouldn.t fit. This meant a delay of two days as this was on a Friday. They brought out a Day & Night unit on Monday and discounted the bill by $200.00. After 6 weeks unit quit working. As we had in writting a 2yr free labor, 5yr free part, & 10yr compressor warranty. We naturally called Cool Breeze. 3hrs later they came out, after checking things out, they said it was a faulty furnace breaker. They gave us a quote of $250.00 to replace the breaker. As this was on a Saturday, and over a 110 out we said okay. Changing the breaker took 1/2 hour. So when the repairman wanted instant payment. We demanded a itemized bill. Other then replacing the breaker we felt the other hour of his labor checking what they installed should be covered under the 2yr free labor warranty They refused and even wanted to come in and remove the replacement breaker. This would have left us with no A/C on one of the hottest weekends of the year. As I am a disabled person this shows no compassion from this company. I turned them away. The bad breaker was a double amp 90, they put in a double 15amp. Way to small. On Monday another contractor came out and replaced their 15amp double breaker with a 40amp double breaker. I called Cool Breeze on Monday and told them they could pick up their 15amp double breaker. It is now Saturday and no effort on their part to pick up breaker. As one other review said run. Don't use them.  We have to agree.

I used to have a contract with this company, but today they charged me $279.00 to install a capacitor  on a 2 ton air conditioner  they installed in 2106 that was under warranty.  Their list price is $125 for labor, so they just doubled !!! So much for honesty!  I would not do business with this company again.
