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.

Matt arrived early (with a call ahead to see if I was available), assessed the issue quickly and had a repair estimate for me within 20 minutes. After I approved the repair, he was able to pick up the part and have the A/C unit in my showroom back up and running in less than 2 hours. He saved the company potential days of rescheduling and thousands of dollars in the loss of potential sales because we could not have customers in out showroom until the A/C was working again! Thank you so much! Will definitely recommend and use them again.

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.

He showed (Matthew) when expected. I was told by the home inspectors that the heater did not work. It fired right up and he did a check on everything. So he was honest and did not try to sell me new unit like the other person did. Saved me a few thousand! These people are honest and very dependable. I would recommend them to anyone. He also installed new thermostat to replace the old one. All in less than an hour. Very good people! Second time out. Matthew installed what was needed. Friendly person and knowledgeable. These people are here to help you when you need it. Would always recommend them!

I was in need of a complete new system install, heat pump and air handler. During the in home consultation I became aware of attention to detail that the other companies didn't offer so I went with Desert Diamond Mechanical. The technicians that performed the work carried over the same attention to detail. The air handler required additional configuration to be the most efficient possible and the end result was more even air flow throughout making for a much more comfortable home.

Even the thermostat is high quality and user friendly. The new system is far above what I had and I'm completely satisfied. If someone is looking for attention to detail and a very professional install Desert Diamond Mechanical is an excellent choice.
