Best Heating & Air Conditioning/HVAC in Arizona

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.

Sammy is the BEST guy in the business. He provides top quality service with old fashioned values and service! Trustworthy, dependable - does what is needed and does it right. If you are looking for an A+ quality serviceman for your heating and cooling needs he IS your GUY!!  #supportlocalbusiness

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

We have used Kilter on several occasions over the past few years. Brett is very professional yet friendly. He explains our circumstances and options and we don't feel rushed to make a decision. He never presses or alarms us. One issue we had was when the fan continued to run after the compressor shut off. He advised us how to shut off the breaker for a couple minutes, then back on again. He didn't pressure us to do the more expensive repair (several thousand dollars)--he said if it continued and we wanted to do it, to call him. Fortunately we stuck it out that summer, often flipping the breaker, but the next summer it only happened once. We completely trust him and his advice. His prices are very reasonable for this level of professionalism and service.

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!

We needed to have the annual air conditioning service done on our 17 year old unit so asked s friend  for a recommendation. So glad we did. They recommended Scott's A/C. They arrived on time and serviced the air conditioner and furnace. Although there is no problem with the unit at present, they explained what I could expect in the future. No high pressure....just honest opinion.  The service was very reasonable and I definitely will have them again.

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

Worked with Thad. Very nice gentleman, not out to sell anything, just to do his job. Had a job quoted at well over $3000 by Sterling Services (horrible company, both their plumber and A/C guy were incompetent and very rude) and Thad got it done for $775. For the price that Sterling was going to charge us, we almost could have replaced the entire A/C unit. Thad got in and out within a few hours. Repaired the same day and was extremely respectful. I would (and will) recommend him to anyone!

Our AC went out recently during the evening & Air Now was able to come to our house first thing in the morning. It was much appreciated when the temps were in the 100's! The technician was friendly & was able to fix our AC quickly!

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!

Completes 90% of work and will gladly charge more to complete the job.

During our HVAC inspection/service and altered tech to wiring concern on the roof. Thermostat wire from roof penetration to the unit was exposed, sun damaged and frayed, also assessed by tech requiring replacement as could short the system. Asked him to cover/protect wire (PVC pipe) but can only assume tech thought no one would look at the covered up wire. Not all wire on the roof was replaced, as we found old frayed wire by roof penetration upon review of work completed.  

We alerted the company and tech came back out and said that is how they correct it as he can't replace all the roof wire as it would put a hole in the roof, although the wire comes through a hole in the roof. He talked to his supervisor and said he could splice the new wire in the attic, creating that hole in the roof he couldn't do before (he wouldn't be able to seal it), but that would cost another $300 approximately to not have any damaged wire exposed on the roof; already paid over $400 for the incomplete work. If you like a job almost but not quite done, then this is the HVAC company to call.
