Best Home Energy Assessment in Phoenix AZ

Alex and Elena were outstanding, informative, courteous and caring.  They answered all my questions during the energy audit for APS.  I applaud their professionalism and informative facts.  I would highly recommend them to anyone interested in an energy audit and they are APS approved.

Steve and the install team did a great job.  Can't say replacing an AC unit is fun but the team at Desert Diamond took the sting out.  Good group.

I chose Preferred Air for routine AC maintenance. Daniel did a very thorough job of cleaning and examining the whole HVAC system. He explained any potential issues that I could have in the near future, and he had some good suggestions on things that I can do to extend the life of my AC unit. Daniel even made some custom-sized air filters for me because my air intake is a strange size.

If you are looking for HVAC services that use the ounce of prevention is worth a pound of cure approach, then Preferred Air is a great choice!

Chris, came to our house and did a thorough inspection.  The representatives are courteous.
