Best Preventative Maintenance in Phoenix AZ

Great service

We use Scottsdale Air twice a year to provide systems checkup and service. Last week Bonz Heideman, Scottsdale Air service tech, provided our winter tuneup. We appreciate his complete review and service to our systems. I recommend them to anyone who is looking for well trained HVAC technicians..

I had been quoted a very high price by two other AC companies to replace our worn out AC. Someone we knew recommended 911 Heating & Cooling. We were given a great quality AC at an affordable price for us. From the beginning, we had prompt communications and updates. The install was fast, and they cleaned after installing. We were satisfied on every level and will use them again for service and help on a plumbing issue we have. I confidently recommend 911 as a trustworthy, quality company you can count on.

Chase is a friendly, professional, and excellent air-conditioning technician. Thanks Chase!Ender Quinones

Great experience, from scheduling through to the service. Luke went the extra mile to get my thermostat replaced under warranty, driving from Chandler to Phoenix to pick up a part and get back same day to install it. Price was more than fair. Semper Fi has definitely won a repeat customer in me!

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.
