Best Air Conditioning And Heating System in Phoenix AZ

5 Stars! Sometimes I go there and help them with their EMS items. Shortly after, I get a donation to my family's well being. They are a great business to assist in helping both commercial customers and school districts save money, while ensuring their partners (employees) are taken care of!

I found their service to be exceptional. Very knowledgeable ,thorough and friendly! Ask for Craig, he really knows what he is doing. A real problem solver. I'll recommend them to all my friends.

I was very happy with the service, responsiveness and professionalism 911 heating and cooling provided! My AC stopped working right before it was about to hit 100 degrees and they were able to fit me in the next day and I felt very content with the service they provided. I will definitely be using them in the future! Thank you 911 heating and cooling!

Enrique was very friendly and knowledgeable in helping me gather information. Performed a thorough inspection of my two systems and was great to work with.

It was super easy to setup an appointment and our tech showed up on-time was very informative and friendly. We would for sure call them again with any issues!

Left the clothes in my closet completely covered in dirt and filth top to bottom when accessing the attic for system work.

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.
