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.
