“Nixa is a very detailed oriented HVAC tech, very rare to find a technician that cares about customers. Dakota went above and beyond in taken care of our thermostat replacement,. Both should be recognized as employees that have exceptional people skills .”

“The tech called me to let me know approximately what time he would arrive and the company sent me his picture. The picture was very helpful to know I was opening my door for the right person. Antonio was very polite and got right to work.”

“We had our old air-conditioning unit replaced with a great new a great new Trane unit. The guys at Desert Diamond Mechanical had the best price, quality and maintenance of the five companies that we had give us a bid. From our first visit to our last the guys at Desert Diamond Air were very respectful of our home. They installed the unit and cleaned the air ducts in one day. I would highly recommend Desert Diamond Mechanical to anyone in the valley. The company is great. Give them a call you will be happy you did.”

“Same day service as request made. Installation of new thermostat was quickly and expertly completed. Made sure I knew how to work new thermostat as it is different – and much simpler – than older one. Appreciated that technician did a great job of using space created for old thermostat so that I have zero touch up to do.”

“Was very impressed with Tyler who was our initial contact. He came over and took a video of the current system in the attic. Tyler explained everything in full detail and made us feel more informed than pressured. We were able to schedule the replacement a/c in 3 days, and the team who came was amazing. They worked super hard thru out the day and was courteous to answer our questions thru out the process. Our units were very heavy and tight squeezes, and this team did an amazing job working together.

A couple days after the install the unit was making a slight sound, and I reached out to Tyler to see if that was normal. Tyler texted back that night and scheduled a check the next day, which I thought was fantastic. Everything with the units were just fine. The company reached out and scheduled a mandatory quality control check to look over the units and to answer any pending questions. All in all we are a very satisfied customers and would recommend this company moving forward.”

“I had them install a Trane system on my house just over a year ago, and I was very happy. So now I had the come out to do a summer maintenance, and they hit me with an estimate of almost $600 to do suggested repairs to it. You would think after spending thousands of dollars on a new A/C system it would not need suggested repairs for several years of use. Not sure about the ethics of them right not, maybe their employees are in performance pay and the basic $99 service charge is not enough for them to live off of?”

“I have always been happy with my maintenance plan; every spring and fall. But this year they more than doubled their fees for the service. I have three AC units and three furnaces. Last year, I paid $400 for tuneups in the spring and fall. I was just told that my plan would now cost $900. This is An increase of $500! As much as I have enjoyed desert diamond (I even used them at my last house), I am forced to look at other companies now. Note – We are no longer in 2020 with crazy inflation and supply chain issues. The last time I watched the financial news channel, inflation has dropped from 9% to 3.8%. How much profit does someone really need to make on routine maintenance?”

– Bill K.

“Daniel was new to me, so I was a bit apprehensive. It was a wasted worry. He was polite, professional, and extremely thorough. I definitely would like him back for my furnace tune-up in the fall. Once again, I was highly pleased with someone from Desert Diamond Aire.”

“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😁”

“Can’t use your text referrals to review work done by Dakota on Friday. Probably unAmerican of me but I don’t participate in social media. Dakota was prompt, courteous, and thorough in his work. Thank you.
