Desert Diamond Air Cooling & Heating

Dakota and team were fast and super helpful, would recommend 100%!

I called Desert Diamond Mechanical to get a quote on a new unit. Steve called me back. Took some information, he very professionally answered all my questions. Within 15 min or so he emailed me several options( different options are always good). I Would highly recommend based on the professionalism alone.

P.S so it turns out my best option was to replace system. Desert Diamond Mechanical was great they scheduled an install right away ( 3 days ). Install was today. I am extremely impressed with the team of professionals that work at Desert Diamond Mechanical, the installers Estevan and Dennis where great they said I would have service in 6 hours and I did. I also asked them to get me info on insulation and Steve Schilling stopped by just as they finished up and gave me 2 options of estimates.. I really like the way Desert Diamond Mechanical does business, and I highly recommend them.

Ivan is very knowledgeable and takes the time to explain and answer our questions. We trust this company to give us good service and products.

This establishment is true to their name! Their communication, attention to detail, the plethora of information shared was beyond expectations. Matt came out to assess our issues, he took precise measurements, provided options to units and financing. It was a one-stop-shop and we are grateful! On installation day, the guys, Alex, Alexandro, and Anthony showed up on time, called ahead, and went right to work. They installed two (2) units, duct work, new filter grates, thermostats, AND cleaned up within 6 hours. We are beyond grateful for all their hard work, especially in this Arizona summer heat. We are extremely thankful and grateful to all of you!
*update - 2 weeks after, post inspection by Trey and his professional courtesy is beyond reproach. Excellent communication, careful attention to all that was needed. What a Blessing for him, the entire crew and this Desert Diamond. Thank you ALL!

Joel was very knowledgeable about our zone system and efficient about replacing the needed parts and making sure the system was working properly.

My service tech, Nexa, was fantastic! She diagnosed the problem and advised me of the specific parts that were in need of replacement and the cost of the all the work prior to the repairs starting.

Loved the service. We have already given out the company’s information to 3 neighbors. We started with an energy audit and were connected with them. If you think you are spending too much on your power bills please consider getting an energy audit and use Desert Diamond Mechanical Heating and Cooling for your HVAC needs. We would highly recommend them. Thank you to all of the staff we dealt with.

Tech Branden came out and took care of my air conditioner. I was so grateful, I called about 4:15 pm and he was at my house shortly after 5. The house was beginning to get really warm. Branden was amazing, he was very professional and explained to me everything he was doing, he was very thorough, by the time he left there was no doubt he cared about making the quality of service I received was important. I am very much a customer type person, I’ve worked as a customer service job and believe it is very important to provide the service the customer expects. Brendan is a top notch technician, very impressed and totally satisfied. Therefore, I will use this company in the future.

Trey is one in a million, He called me ahead of time to let me know he will be at my house in 30 min or less, and he showed up on time! He was super nice to my 2 dogs :) Trey is a very professional technician, he knew the project that needed to get done and finished in a timely manner. I strongly recommend Trey and Desert Diamond Mechanical Heating & AC to anyone. I am extremely happy with the service that was provided!

We have used Desert Diamond Mechanical before. But never in our 35-year marriage and our 5 years in residence here in Surprise, Arizona have we ever had the top-notch service that Hayden provided us with. He cared enough about us to come back after his long day with the part he needed to fix our furnace. We are seniors and he just flat out cared about us. Heads up to his boss, Cody. Hayden is a keeper.
