“I've been doing business with Desert Diamond for at least 8 years. I cannot say enough about the staff, and the service technicians, especially Daniel M., who was just at my house this morning for general maintenance. I trust them so much that I even do five-year contracts. My granddaughter also has a contract with them. Her AC went out at 11p last Friday night. They came right out and did a great job on a holiday weekend! Great job, great service! I highly recommend this company!”

- Dee G.

“I work from home and needed someone to come out and check my AC asap. I called at 8 am and Antonio arrived by 10 am!
He answered all my questions and made sure everything was running smoothly.
Thank you for my piece of mind Antonio and Desert Diamond!
So grateful for your quick response!”

- Michele W.

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.
