Desert Diamond Air Cooling & Heating

Isaac did a wonderful job on my air conditioner. I love Desert Diamond Mechanical. They are a tip top company and wonderful employees. Isaac changed my in door filter and washed down my outdoor screen. Thank you Isaac, and 👍 great job. Cheryl Campbell

AC went out when it’s 113 outside :/ Tech was able to get to my property same day and resolved issue in 30 min. Great service, will use again if trouble comes knocking. Thank you

Beat deal for the service provided. Searching for a good hvac company can be daunting here in the valley. I got estimates from a dozen companies before choosing diamond mechanical. There is service and then there's value. They wrap it all up into one great package. Clean professional and honest.

Ivan was outstanding. First he came to check out our system do to an error message on the thermostat. He researched the problem and then came back to do the repairs. He was really good. He was courteous, respectful, prompt, and made the repairs in an excellent manner. The system now works properly. We need more professionals like Ivan. 5 stars!!

Nixa was very knowledgeable of what needed to be done to fix our AC unit. She was quick and friendly. This was the 3rd company we had come out. We are very grateful for Nixa and Desert Diamond Air.

Julio was our service person today. Came in a timely manner, reviewed the system to find the problem and fixed it. He answered questions and was good at explaining the details. Would highly recommend Desert Diamond heating & cooling.

Nixa was excellent, explained the entire repair process and answered all my questions .I will definitely use Nixa and Desert Diamond for regular maintenance.

Fantastic service from start to finish! My my very professional, highly knowledgeable expert Trane technician went above and beyond in every way. Total fast, friendly and reliable service worth every penny in my humble opinion. I won't call anyone else in the future. I checked the BBB and the AZ ROC beforehand, but now I truly know that Desert Diamond Mechanical is the best in the Arizona.

Julio was fantastic. Took his time inspecting each part of the system and gave honest reports as to the quality of our current system. He was incredibly knowledgeable.

My service tech,Erick, was very nice, polite & professional.. explained everything so I could understand., I felt he went over and above, even changed my filter & vacuumed the vent cover!
