    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.!!

    Thank you Desert Diamond Mechanical for the positive experience we had during the purchase and installation of our new Trane XV18 ac/heat system. We are enjoying our new refreshing atmosphere. The service tech was informative and helpful in guiding us toward our new system. The owner, office staff, and installers were very professional and were a pleasure working with. We highly recommend Desert Diamond Mechanical for all your ac/heating needs. Thank you all again, Fred and Patty Sun City West

    Use Desert Diamond before so when the AC stopped blowing cold they were who I went back to. Called at 5PM and the girl there was very helpful and told me somebody would be there the next day. Cody turned up by 10AM and diagnosed I needed a new coil. I have aTrane and these coils were not a stock item but Cody went out of his way to get me one from out of a stock unit. Early return. problem solved at and very acceptable price. Thanks Cody, the girls in the office & Desert Diamond

    Had ac problems 3 weeks ago,called 5 companies 4 put me off till Tuesday . Rocky came out it was Sunday and hot . My unit was 17 yrs old and he got it going for us. He had to order parts that took 2 days to get but he got it working . I didn't want to keep throwing money at it. Ask rocky for a quote on a new unit had it in 30 minutes. Didn't try to shove anything at me. I decided to go with it. Rocky set up the install,right on time Frank and Austin were great. I'll never use anyone else 10 star

    Bought a new Trane air conditioning unit last year, Steve was very helpful with the entire process. For the preventive maintenance this year, Steve was the technician who assisted us again, he has great work ethics and very knowledgeable about the equipment and maintenance.

    We just received a new Trane total system. Steve was our estimator and explained all the options thoroughly. He was transparent, no gimmicks and did more than any other contractor(5 total) to honestly earn our business. The crew led by Ben was so hard working, polite(including to each other), friendly and informative. Ben's technical knowledge was impressive. You can be sure he has years of experience and schooling. Great experience! Thanks DD..!

    I made an emergency call to Desert Diamond Mechanical today due to no AC. Cody and Justin came out in a timely fashion. They were respectful, polite and knowledgeable. They explained everything, photographed the problems for documentation and for me, answered all my questions and didn't try to sell me anything. I recommend them to anyone looking/needing service. Great service, great people, reasonable prices.
