Craig did the inspection and quoted me different AC units. He understood my needs and budget, and provided the best quote between 3 companies for same models. He answered calls and text when I had questions. Brody and Joshua did the install, including a new thermostat and new vent. Fine young, hard working folks. Highly recommend them!!
Timothy was absolutely amazing! He was incredibly helpful, took the time to explain everything clearly, and made sure we fully understood what was going on with our AC unit. He didn’t rush the visit and patiently answered all of our questions. On top of that, he’s just a genuinely great person, super nice, professional, and extremely knowledgeable. It’s rare to find a technician who combines expertise with such great customer service. We truly appreciate his work and would highly recommend him to anyone!

Another good day with Desert Diamond Air!! We have been having our central A/C taken care of by this company for years now and it is always the same, AWESOME! They have some of the nicest service people and the office people are just as kind and polite. This year we had Phillip. He was prompt, informative and all around excellent. We HIGHLY recommend their service contracts which save you money and also provides prompt service.
Desert Diamond replaced two 5-ton AC units for us this week and from start to finish they were straightforward, knowledgeable and efficient. The sales rep Tyler answered all of my questions clearly and took his time explaining his answers. He responded quickly along the way and was a pleasure to work with. The crew on install day were friendly, efficient and did a great job cleaning up after their work. We got four quotes before deciding who to go with and I'm glad we went with them.
I had Tyler out to give me an estimate to re-insulate my attic. Tyler showed up on-time, was very thorough and presented me with several options at different price points. Ultimately, I went with another company that was slightly cheaper for the same scope of work and with whom I've had previous experience. That said, I would not hesitate to call Desert Diamond again in the future because of their communication, ease of doing business and professionalism.
