    Contacted Desert Diamond and was able to get a technician that same day! I just had an inspection for the sale of our home and it needed some minor stuff and we are moving to GA the next day. They did not try to up sell me and Nixon did a great job with shceduling me in to work with my situation. Spoke to jeff over the phone and he was very honest and knowledgeable . They sent Ryan over and he was fantastic He was Honest and he really cared about our situation. Great team work here!

    Our AC went out and the first company we tried to use ended up being a no-call no-show. I called Desert Diamond Mechanical and they had our AC up and running again less than 12 hours from the call. Ryan was incredible, a true professional. I can’t recommend him enough! I’m definitely signing up for regular maintanance plan with Desert Diamond. Great, honest company with fantastic employees. Thank you, Ryan!

    Steve came out to our house on an emergency call at 10pm and was wonderful! Very friendly and professional. He got us up and running in no time and made sure that it was fixed correctly. We will definitely be calling him for our annual AC check up from now on. Steve, thank you for your expertise and professionalism.

    The Desert Diamond team are true Professionals with a plan. We had a total shutdown of our AC system the last week of July and we were fortunate enough to contact Desert Diamond and their great contact team and explain our situation. Jeff was sent the next day and was able to get our older unit fixed and running better than ever! For what needed to be done, Desert Diamond has very reasonable pricing with quality work to boot. A pleasure to work with them on this Emergency.

    Steve at Desert Diamond did a great job fixing a repair that didn't go quite right the first time. He was prompt, professional and knowledgeable. He explained everything he did to make the repair. My husband and I really appreciated that he made it right with out any hassle. Thank you for the excellent service!

    I highly recommend Desert Diamond Mechanical. I met Jeff at the Pora Vendor Show, he was so pleasant, professional and extremely informative. Jeff came to my home and gave me an estimate for a Trane Heat Pump System. and installing a Duct system and vent in my Laundry room. I had my installation of my Trane Unit today by David and Austin, they were on time, very pleasant, knowledgeable, and very professional. It was a pleasure to work with David, Austin and Jeff and Crystal. Sharon SCW

    Desert Diamond recently replaced my air conditioning system with a new Trane variable speed unit. This company has been absolutely awesome from the first visit to evaluate my old unit and provide me a quote for a replacement unit. Cody was extremely knowledgeable and did a great job explaining the entire process of replacing our equipment. Ben and his crew did an outstanding job installing the equipment and completed the entire job in half a day. Great work everyone.!!
