Best Heating & Air Conditioning/HVAC in United States

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!

Had a unit fail on me Friday, Sept 5. I am very grateful with same day diagnostic and repair. Part was covered under warranty and service call was reasonable. My tech was Jonathan who arrived  when he said, and was very thorough in explaining the issue. I've always gotten outstanding service from Clayton and his team. Thank you!

I selected Temperature Pros from the business directory of the Glendale Chamber of Commerce, since we needed AC service prior to the hot Arizona Summer.  John's team came and did a great job!  They are professional, efficient and reasonable!  Our AC is actually working better.  I highly recommend this business.  John McCoomb is the owner.  Tell him Cooki sent you!

We were in a bind and they came thru. Benny was honest and helpful. Would recommend, thank you!

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.

Also nice when you when you have a problem and the people you hire solve it without any issues. I'll be looking forward to hiring all the Williams in the future for all my home repairs. Thank you

After another company came out and could not diagnose the issue with my A.C. I called 911 repair. Dan answered the phone and scheduled a technician to come first thing the next morning. Vic came out and found this issue, the following day Vic worked to replace the broken part, a valve sensor. He spent 3 hours in my attic on a 110 degree day and fixed the problem. 911 saved us!! I will always call on them for any A.C. issues I have. They are courteous, prompt, and know what they are doing. Thank you 911!!!

Our AC went out in the middle of the night. We called first thing in the morning and they came and fixed it by that afternoon.

What a lifesaver. Come home after work to a 90 degree downstairs. My wife found Mikes number,  called and 20 min he was over and fixed my AC... thank goodness because it was HOT.  Will definatly call again.

Our upstairs a/c stopped blowing cold air. On a 109 degree day. Sunday afternoon.
We have a brand new unit under warranty and the company that installed the system doesn't work on weekends. In the past, with our old units, we used a myriad of companies but none of them stuck with us. They did an ok job, prices were pretty steep. It was time to find a new company

Cue Clark. Professional and courteous on the phone, text schedule updates, the tech called when he was 30 minutes out. The tech, Sam, was super duper nice. He is the Mary Poppins of service techs. Turns out the ductwork in the attic had fallen off the handler. Great. So he repaired it, checked our fluid levels and with our consent balanced the refrigerant.

When he was done he cleaned up, I paid and the invoice was sent electronically via text and email.
I cannot recommend them enough!!

A big thank you to Richard.  I posted a request for a quote around 10pm and got a response with an estimate along with availability in half an hour.  I was able to schedule the appointment on yelp right away and got confirmation on yelp.  I added one more job after the initial plan and it was gladly accepted.  All jobs were completed quickly.  Good communication from the beginning to the end.  Great experience with Richard.  Thanks again.

Had an appointment for tuesday @ 8 to 9 a.m.  my wife waited for hours and no show. She called this company and the female that answered told my wife that she called and cancelled. So my wife missed a day of work and rescheduled for today. She and i both work so i waited ( 8 to 9 a.m.) about 10 i called and spoke with k____y. She said we did not have an appointment and insisted that my wife called to cancel the day before (which was not true) and did not reschedule. So wether it was k___ys mistake or not she was a bit rude and insisted how wrong i was and said she would call me back. She did call back and trying to be appologetic said some one would be here shortley. They did come as promised and are gone to find a part. Finally, i called work and said i couldn't come in due to this abortion of customer service. My wife and i both missed a day of work. I hope others have had a better experience.

Run do not let them trap you!

They do not show up when they say they will, they have no respect for you or your time. They lie and they overcharge.

They made four promises to us, and they delivered ZERO!  We are without heat for day three and they just postponed us another day.
