Anthony was just here to do our twice a year checkup that we signed up for on contract after using their Emergency Service last year, which they fixed our unit that went out in the summer. They were fast and good then also. He was extremely friendly, very knowledgeable and checked out everything in our system. This company has earned and deserved our trust. Would love to have Anthony back next time we need any service. Thank You guys Very Much !!

Home Owners,
Desert Diamond Mechanical by far was head and shoulders above the rest out of the estimates that i got. Complete professionals with real solutions to my systems problems.
Here is my rating:
1. Communication and timeliness
5 stars
2. Assessment of problems and options for solutions.
5 Stars
3. Scheduling and installation of new Train heat pump.
5 stars
4. Diagnosis of duct efficiency repair and Aeroseal installation.
5stars.
5. Total cost - low competitive. However installation and duct repair was above and beyond what could have been expected for the total cost.
Great Value!
5 stars.
Furthermore they work with APS and were able to provide the rebates available from APS up front reducing immediate out of pocket costs.
Desert Diamond Mechanical is the whole package under one roof with a great crew of guys.
Thank you Steve, Ben and Jay.
Results. First full month of use we received a "congratulations" from APS on our bill because we had a 25% reduction in energy use and in the amount of our bill.

I cannot say enough about the service from this company. With the outside temperature of over 110 degrees, Corey was at my home within an hour. The temporary fix worked for a while and no charge for the second visit. Making the decision to install a new unit, again a temporary fix made me comfortable till the unit was installed. Every one of the employees were very accommodating and I was impressed as how quickly the job was done. I strongly believe that you could not get better service!

Customer Testimonials

Desert Diamond Mechanical is the best heating and A/C Company I have ever dealt with. Calls into the office are always answered right away by a smiling voice and returned calls happen very quickly. I was so impressed with their level of service that I purchased a service contract with them that gives me service with any breakdown within 24 hours. This summer my A/C unit went out, and in the past when the other guys were telling me that I would have to wait days without A/C for someone to come out to inspect my unit because it was summer and they were busy, Desert Diamond Mechanical was at my home within 2 hours and had my system up and running. They even took care of dealing with the warranty on my A/C unit for me and the repair cost me nothing. I have tried other service companies, but these guys give real meaning to the words service and customer service. I am also a Realtor in Phoenix AZ and I use this company for my own personal residence as well as refer them al all of my real estate clients.


I was having problems with my ac a few days ago. The weather had just gotten too hot and my air wasn't working. I called Desert Diamond and they got a tech out to my house the next day. They checked every thing out and got me up and running the same day. They are fast and reliable. The tech was nice and the cost was much lower than some other companies that are out there. Right now on my budget every dollar counts. My air is running and I'm a happy customer. I would recommend them to anyone who needs service, especially if they need it quickly.


Desert Diamond Mechanical Heating & Air Conditioning is a fantastic, trustworthy company. We were very pleased with the service we received when we had two heat pumps replaced. Cody manner makes you feel at ease. He is very knowledgeable, professional, and informative about the heat pumps they offer. The entire service crew, led by Ben, was terrific. They brought everything they needed to keep our house as dust-free as possible and make the installation pain-free. We observed how they worked cohesively and efficiently as a unit. From the top to the bottom, the owner and staff were eager to help, friendly and the most customer service oriented people we have ever dealt with. The follow up visits have been nothing short of top notch. We would definitely recommend Desert Diamond Mechanical Heating & Air Conditioning to our friends and family.


Desert Diamond Mechanical are by far the best Heating and Cooling company I have come across. There professionalism stands out above the rest. Special thanks to Steve whose advice and follow up was second to none, his and Jason's full evaluation of my air conditioning was enlightening and while I did not go with all there recommendations they execution and follow up was faultless. Their air improvements as well as the new air conditioner has saved me on average $125 a month. Fully recommend them.


I rarely write reviews, but Desert Diamond definitely earned 5 stars. When my AC unit went out late at night and we needed emergency service they were there with courtesy, promptness, and professionalism. Our air was back on within an hour and we avoided having to stay in a hotel. Special thanks to Cody, our technician, who despite the late time was pleasant, professional, and courteous. Definitely earned my repeat business! A++


I didn't realize my air stopped working until after 9 pm. I got a prompt response to my call rather than hold music, and they gave me a window for tonight instead of making me wait until the morning. Anthony provided exceptional customer service despite the late hour, during what I imagine is a busy AZ summer season where ACs are breaking all over the place. I'm very happy with the service provided, and I'd highly recommend their team for anyone looking for prompt, reliable AC maintenance and/or repair.
