Best Businesses in Phoenix, AZ

Best AC company in AZ! Fast and quality service at a fair price, plus Craig, the owner, is just an all around nice guy. I have been working with these guys for years now and recommend that you do too!

Paul impressed me greatly because he was courteous, answered my questions, and pointed out what needed to be replaced. He also talked about the various maintenance programs and what they covered. Sheffield Heating & Air Conditioning will be highly recommended to my family, friends, and neighbors.

Good service good technicians. They take time to know their customers as well...

I was out of cool air for more than a month this pass summer waiting for service for my unit. A friend told me about Mike. I called and talked with Mike about my problem with the unit. Mike was able to take care of the air- conditioner within a week after looking at the unit. Mike did an excellent job communicating with me about the unit. He has excellent communication Skills, kind, honest and very polite . I would recommend Mike to anyone needing air conditioner service of any kind. I give Mike Garcia A+ !

We had a great experience with 911 Heating Cooling & Plumbing. They were on-time, efficient, and offered their service at a fair and reasonable price. We will call them again the next time we need similar services.

John is prompt, knowledgeable, highly qualified, and super friendly. He is a top notch tech/salesman! I will recommend him to everyone I know!

Great customer service ?

If you’re in need of an HVAC company look no further. Jonathan and Sarah at High Efficiency Heating And Cooling are amazing and such a blessing. Can’t say enough great things about their quick response and willingness to come out diagnose, and fix my broken A/C after the first 100 degree day in Phoenix. Highly professional, knowledgeable, exceptional work, prompt, friendly, and most importantly trustworthy. So thankful I was led to this company. Definitely recommend them to anyone with an HVAC need.

Amazing company and products hands down .
