WHAT OUR CUSTOMERS SAY

“We completed install of our new Daikin 3 Ton, Two Stage heat pump today and want to give a positive shout-out to Zach and his helper (whose name I didn't get). They did a great job in a friendly, professional manner. Zach was patient showing us how to use the new thermostat and getting it on-line which is a great improvement of the old one. This new unit is blowing serious cold air in a surprisingly quiet manner. We highly recommend Zach, Aaron, Daikin and the Desert Diamond team.”
- Patrick D.

“This company is top of the line. They have been servicing our A/C unit for about 5 or 6 years now. They have always done an awesome job. From the young ladies that I've dealt with on the phones to the different people who have serviced the A/C over the years its always been pleasurable. Nice, polite and helpful. The service techs do a great job maintaining our unit.
The young man who took care of us today, Timothy, was nice and polite and informative. GOOD JOB EVERYONE! Thank you!”

- Vivian D.

HOME PERFORMANCE

At Desert Diamond Air, we take a whole-house approach to ensuring your home delivers optimum comfort and energy efficiency.

Our technicians are certified by the Building Performance Institute (BPI) and are experts in home performance solutions. We identify areas that need improvement in your home and find ways to fix them:

  • We know that even a top-of-the-line heating, ventilation, and air conditioning (HVAC) system alone cannot correct the deficiencies caused by poor insulation, damaged ductwork, and drafts.
  • Let us conduct an energy audit in your Greater Phoenix home and recommend a solution to improve your energy bills and comfort.
  • We offer attic insulation, Aeroseal air duct sealing, and duct cleaning and duct fogging to enhance your home’s performance.
