All reviews for Desert Diamond Air Cooling & Heating

Leo and Joseph were fantastic. They arrived on time, worked efficiently, and handled the HVAC service with total professionalism. Both were friendly, knowledgeable, and respectful of the space. They diagnosed the issue quickly and got everything running smoothly, all while explaining things clearly and offering helpful tips. You can tell they take pride in doing quality work. Highly recommend this great team!

This is by far the best company here in Arizona if you need your AC fixed or a new unit, they are knowledgeable experience, and most of all honest they are not out here scamming at all like a lot of other companies we have dealt with bad companies we hired them and they came out very quickly. Leo was great and so is Aaron. I would absolutely 1010 recommend to anyone reading this. Please reach out to them. They are affordable honest and overall so great like wow These men deserve better The Best

Dominic was phenomenal! So helpful, friendly, professional. Such a joy to work with. I'd like to work with him anytime!!!

After signing up with DD for annual service on our old HVAC systems, we eventually had two new units installed and we are very happy with Desert Diamond! They are very friendly and professional. They service our units twice a year and we’ve never had any hassles. I definitely suggest getting on their maintenance contract plan! You are a priority especially in the summer months when things can get very squarely and uncomfortable!!

Maison Clark was an amazing tech, very professional and knowledgeable. He inspected everything and made sure the equipment was running efficiently. In this crazy world today it's nice to see young men who are not only respectful but also take pride in their work. Thank you Maison.

Desert Diamond installed a new package heat pump and modified some duct work. Aaron did a great job explaining what needed to be fixed and checked on his guys during and after install. Could tell right away it made a big difference from old unit and the existing not-so-great duct work. One bedroom furthest from the unit was a little warmer than the rest of the house and Aaron came out to make adjustments. Feels great now and hoping it stays that way!

Desert Diamond’s Aaron Hoberg did an excellent job presenting our options. They had the best deal fairly presented. Highly recommend Aaron and Desert Diamond.

Has maintenance checkup on 4 AC units. Technicians were very professional and did a great job.

Impressed with the quality of service. Our technician was knowledgeable, prompt, extremely courteous. Would recommend and will continue using desert diamond

Arturo was professional, knowledgeable, and honest from start to finish. He took the time to explain everything clearly and helped me understand the condition of my AC unit without any pressure. He was thorough in his inspection and gave me realistic options for repair based on urgency and budget. After his quick fix, the AC was back up and running—bringing the house from 100 degrees down to a livable temp, just in time for showings. I truly appreciated his transparency, punctuality, and expertise. Highly recommend Arturo if you want someone who knows what they’re doing and genuinely cares about helping you.

It began in January 2018. I got a crazy idea to move our kitchen to give us an open floor plan. Our home is a John F Long home built in 1977. It was a very difficult task to find a competent HVAC company to do the difficult re-engineering of our system. I finally found Desert Diamond Mechanical. They had to move intake and take supply to wall not an easy task to engineer or install, but they came through and knocked it out of the ball park!! I had the pleasure of working with Rocky at the onset- On to Ben to determine if design would work properly, then onto the crew that helped Ben with install- David, Frank, Austin, and Wade. It went very smoothly and works fabulously. Ben really helped relieve my stress of the whole thing with his fun sense of humor.

It turned out beautiful and works wonderfully!

Thank you Desert Diamond Mechanical,

We reached out to inquire about your maintenance program and spoke with Aaron. He was so knowledgeable, helpful and respectful. We received our estimates promptly and were able to schedule service quickly. Highly recommend.

My Service Tech was Dominick. He was fantastic. Knowledgeable and courtesy explaining everything to me. Very good experience.

we have 3 air conditioners to replace. Tyler was on time (actually I was a little late), he was very courteous and professional. Was very knowledgeable with the products he was presenting.

Dominic arrived on time and was very polite and courteous. He did a great work and also replaced my filters. He made sure I had no questions that went unanswered. I highly recommend dominic

Can’t say enough great things about Desert Diamond Air. Our ancient AC unit finally died last week. Steve came out and went over our options, explained to us the process, and gave us a timeline on how long the new installation would take. It was relief to work with such an honest guy and company when making a large purchase. The installation went exactly as Steve had explained. The installers, Josh and Estavon, did an excellent job and left the area they worked on looking better than when they arrived! Our new unit is working perfectly and so much more efficiently than our old one. Desert Diamond Air is THE BEST!!!

From the lady who answered my call, I am more than satisfied. The gentle lady was quick to find me a technician in my neighborhood. And Dominique was fast to rescue me. He is a great guy and very professional. He didn’t only repair my HVAC, he inspected the whole system, provided me with advises and won my trust for me to take up membership with Desert Diamond Air Cooling & Heating. I recommend Dominick and Desert Diamond Air Cooling & Heating for anyone with HVAC issues. Thump up Dominick!!

Arturo was very knowledgeable and courteous. His inspection of my units was thorough, and he took the time to give me some suggestions for future energy saving measures. I would recommend his service anytime.

Very fast service and friendly staff. Fair and honest assessment of opportunities. Dominick, our tech, was great!

Incredible company and staff. All very professional and kind. From the office team, Steve for estimate and recommendations, to Josh and Esteban for the install and explanation of the system. I couldn’t be happier with the entire experience. All companies could learn from their customer service and actual service. Thank you Desert Diamond for a job well done. I love my new HVAC!
