“Can't say enough good things about Desert Diamond Air. I was dreading replacing my 18 year old AC, but the process was much easier than I anticipated. Everyone I interacted with at Desert Diamond Air was fantastic. Tyler came to my home, answered all of my questions, and provided me with the most detailed and easy to understand estimate of all 3 companies I got estimates from. A few days later Shawn and Alexandro installed my new AC. They were friendly, worked quickly, and took great care in making sure everything was done correctly. A few days after that, Nixa came by to do the post-installation inspection and made sure everything was in tip top shape. Her attention to detail was top notch. Lastly, Cambria in the office is so nice and kept me well informed all throughout the process.

The new unit itself (Trane XV17) is amazing. I was skeptical of reviews that said "it's so quiet, I can't hear it running." I thought to myself, that's dumb, it has to make noise. But to my surprise, I can barely tell when it turns on. So much quieter than my old unit. Looking forward to seeing how it performs in the Arizona heat.

In summary, I wouldn't hesitate to recommend Desert Diamond Air. An A+ experience start to finish. Thank you!”

“I can’t tell you how pleased I am with the entire experience I have had with
Desert Diamond team. Steve S came to discuss my needs and gave me all of the options. He was very professional and kind. He came back to do final measurements and take photos. He was amazing. Then on install day, Josh and Esteban came who were equally professional and kind. They went out of their way to make sure the install was perfect and running smoothly and in such an expeditious manner. I highly recommend Desert Diamond from the 1st phone call to the equipment explanation. Thank you all for an amazing job😁”

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:

  • 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.
