Best in Phoenix AZ

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!!

I echo most of the other comments about this company; the company was fast and professional. Beyond that, however, I appreciated their transparency. They were very careful to always explain what they were doing, and why. As a result, I felt like I they were treating me honestly. I would certainly recommend them.

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

I have had nothing but a/c issues for the past four years, every summer, even in the winter! I had a new unit installed a year and a half ago, and still nothing but issues. Today, this company came out 2 1/2 hours after being contacted on a Sunday, and finally fixed the issues. I have had MANY companies come out and fix my issues but I finally feel like this time it is actually fixed. Thank you SO much. You will be my a/c company going forward and I will refer you to everyone I know and on social media!

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!

Our AC decided to die on a hot summer day last week, and I was looking for someone local who could take care of it same day as we have pets, and it was getting to 94 degrees inside the house.

I called and the lady on the phone was very professional. She had Scott call me and he came out within just a few hours.

Turns out, it was a bad motor (something I suspected based on the noise it was making and the fact that the fan stopped spinning on the AC unit itself), which he replaced and warrantied for a year parts and labor included.

The AC works great, the house cooled off by late afternoon, and all is well. I would call again for service, but I hope I don't need it.

I've been extremely happy, using Top Gear cooling and heating. It is so hard to find an HVAC company that is 1) honest. I've had So many bad experiences throughout the years with crooks before I found Chase (owner of Top Gear Cooling & Heating ) 2) professional, high quality workmanship  3) On time 4) all at a fair price.   When I first met Chase, it was because I hired him to fix a botched job that another HVAC contractor messed up all the duck work in the installation of my custom home. Chase came out and fix the problems right away. Been using him ever since.

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

My gosh. Thad is amazing. His work ethic is unmatched. He was even patient with our yip dog. (Ug!) He really saved the day for us. He gave us an new AC system and got everything working. He even came back to make sure everything was working correctly.

Thad is the most helpful guy as well. To make sure we had AC restored he worked almost 12 hours straight! ...Up in our very hot, stuffy attic!

Definitely give Thad a call.

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.

We called Cool Climate to get a check up on our attic furnace. The entire experience was cool! Passed with flying colors. Wes was the technical expert. Very precise and very honest. We would definitely recommend this business. Thanks!

It is unfortunate I cannot give them negative stars!

Fountain Hills Air Conditioning and Heating in Fountain Hills is patently dishonest. I originally contracted with them in January of 2015 to be covered through 01-28-18 for $465. I thought I was getting a good price but know they are the worst AC company I have ever found. After I had signed the contract, I was advised to check on them through BBB, which I did and was horrified to learn of all the complaints. As I had already signed the contract and did not investigate them until several months later, know that I had made a very bad decision. To add insult to injury, when they showed up in July 2016 to inspect my unit, I was told that the coils were leaking and that the compressor failed on the meter check. I was told that it would be a couple thousand dollars to repair but that they would recommend replacement at a cost in excess of $5,000. I would state here that the unit is Carrier, installed by me on 05-23-2012 with a ten-year warranty that will expire on 05-24-2017. I was very distraught and called another company to check the unit. Ready Air checked the unit and told me that the coils were not leaking and that the compressor was operating at 100%. Jeremy further advised that NOTHING needed replacement! I called Fountain Hills AC and asked for a refund on the balance of the service contract not used only to be told that they would not refund the balance stating that they would then have to charge full price for all the service done since 01-28-15 (including 1/28/15 that would be 4 service calls). This company has taken advantage of me and I hope that my posting will prevent other people from allowing them to steal from you. I seriously question whether the parts they replaced were failing; I am 77 years of age could not climb on my roof!
