Best in Phoenix AZ

These guys are great!  No hassle.  Low charge for service calls - I forget if it is $40 or $60, but either way, it's a good deal for an honest diagnosis.

Amazing company!! Keola, Brennan, Devan, and one other tech (didn't get his name, sorry!) all did phenomenal jobs when they came out to install our new unit and cleaned our ducts and vents. Everyone was thorough, highly efficient, accommodating, very professional and honest.  They had everything timed perfectly which was quite impressive lol Communication was made quick and easy thanks to Julia and Nicole.  They answered all of our questions, addressed all of our concerns and were able to schedule us quickly.  We can't say enough good things about this company.  They are our go-to AC company and would not recommend anyone else.  Thank you guys!

Regular inspections and preventive maintenance takes the worry out of having the air conditioners fail when we need them the most here in the southwest. They are always professional and take the time to explain what is happening or not happening with our HVAC system. We know nothing is going to fail until it is 110° outside, but Red Mountain is always available and i time. They just did a major maintenance on the upstairs HVAC unit as the blower, motor and control board were failing, it was completed in a couple hours, and no discomfort in the house whatsoever.

My technician mike from az perfect comfort came out promptly and fixed my air conditioning problem, even with the temperature at 106 degrees. He worked hard and restored my system up and running. He thoroughly explained the problem and Mike was very helpful. One of the most ethical honest companies I have found for AC maintenance and repair

Very good guys with prices and service and highly recommend them and thanks so much for Benny for his great friendly service,  When I came back Saturday night and found my A/C is down for some reason and called all the air conditioning companies and all put me on thr waiting list then kept trying do my calls on Sunday and no one can come soon then got this company name and Benny responded to my call land came immediately , he fixed the problem with lower coast and shortest time, thank you so much

Trae and Mark did a fantastic job replacing our 4 ton unit located on our roof.  They were prompt and professional.  Mark set the expectation and both he and Trae more than delivered.  On top of that, their prices were very competetive!!  We HIGHLY recommend Top Tier to anyone in the market for a new AC/heat pump.

Arrived on time!  Completed a quick diagnosis of the issue. Replaced a corroded refridgerator waterline. Repair completed in under an hour. We will use again this company again.

Buying a furnace and air conditioner is a big deal. I put a lot of thought and did my due diligence because there was a lot of money involved.  I could not have been treated better by Ray and the folks at 911 Air.  Victor and his installers are very, very good at their job. 6 hours and everything was installed and no mess was left. Ray sent a tech over the next day to check everything and to make sure I was satisfied with the install. I will admit I was a little concerned when entering into this but Ray's customer first attitude and his doing a little hand holding got me through the process. There are no hidden fees or add on cost, everything is up front.  You can trust 911 Air to give a competitive price and excellent service.

I called Cactus Valley HVAC for an AC unit maintenance, Richard, Cedric and Jonathan came out and while they were hear they recommended a duct cleaning. Jonathan came back on a Saturday to clean my ducts. They are honest, fast and are fair priced. I 100% recommend Cactus Valley HVAC.

Mike is worse a/c guy i ever seen....he was late and drunk when show up! BAD SERVICE!   He used stolen parts on my a/c   scam!!!! STAY AWAY FROM THIS COMPANY!!! Would never use this company again!!!

I called RKS at 7am when they opened. No answer, I left a message. I caled Clark at about 8:30am..they said they would come out around 12:00.
RKS finally called when the Clark service men were leaving at about 1:00.
Clark turned out to be great. Very honest. Will use again.

You wouldn't believe how difficult it was to find someone willing to install a flag bracket on a stucco garage! I put the word out on Yelp and Joe Honeycutt  came in with the most reasonable quote among six vendors. He immediately offered to do whatever else I needed within the one hour of his time I was purchasing. Not only did he come prepared with special long stucco penetrating screws and anchors. When I mentioned a ceiling fan that was wobbling at high speeds, he went to Home Depot to get a fan balancing kit to fix the problem. ALL at no extra charge. Great communications in the days leading up to my appt. Clean, friendly, punctual and effective. I recommend Joe Honeycutt very highly.

Major disappointment. First, they were supposed to do our job 10 days ago. it took multiple calls to their office to finally get them to do anything after there initial diagnostic visit. In addition, they charged an outrageous service charge just show up the first time. then, as they needed to order a part,they then charged us another service call charge to install. The job took 5 minutes for their tech to do as they just needed to change out a minor part.

We used this company 3-4 years ago, and they were great. Very disappointing this time. So we will look for a new heating and cooling company for our future work. Do not recommend at all.

If I could give them a zero I could. Really ripped me off and tried to do it again but fortunately I found Cave Creek Cooling.  Buyer beware.  If the offer seems too good it usually is.  They will get you coming and going especially if you cannot get on the roof with them.
