Exceptional customer service and professionalism. Great communication. This is one of the best experiences I have had with a contractor in Scottsdale. You won't be disappointed if you call this company for AC services, repairs or replacement. I will be using them for all of my ongoing maintenance needs.

Our friends at 911 Heating, Cooling and Plumbing have been wonderful and very accommodating during several weeks of our HVAC problems, which we are so happy to have solved!

Excellent customer service and very fast affordable work. Very genuine workers. Definitely recommend!

Hello — for the past 2-3 months, my HVAC was running constantly. The problem seemed to show up when I switched from cooling to heating prior to winter.Aaron from Semper Fi arrived and immediately diagnosed the problem. It appears a wire in the thermostat was not placed correctly causing the fan to run all the time.I am grateful that Aaron helped us so quickly. Hopefully, our power bills will decrease.Thank you, Aaron!

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.
