    The team of aeroseal techs were excellent! Austin, Steven and Andrew were knowledgeable, conscienctious and respectful while performing the service. Thanks to their efforts the sealing of ductwork is providing a much more efficient cooling system.

    I called Desert Diamond Mechanical after hours on a Friday, Ryan, the service tech, showed up within an hour. Ended up needing a new AC unit, Ryan helped me pick out the right unit for our family, and took care of all the details, great customer service. The install crew (Frank, Wade,and Austin) showed up on time and did a great job. Quick, clean, and professional. I would highly recommend Desert Diamond Mechanical to anyone.

    Desert Diamond is a great reliable company. They are always very nice and extremely helpful. Getting the maintenance plan is absolutely worth it. And although the company itself is great what makes me keep coming back are the technicians. Specifically we have a technician named Cody who always goes over and above each time he comes out. He is extremely knowledgeable and informative and explains things in a way we understand. Cody is what make Desert Diamond the premier AC Company in the valley

    After contacting 2 well known ”reputable” companies that said I would need an entire new unit replacement & were charging $5000+, Cody rescued me! He was thorough and HONEST. He found that there was simply a wire disconnected from the circuit board. I was so GRATEFUL & RELIEVED that I almost cried. In this day and age you cannot put a price on honesty. I will not be going back to my other company. I will be using Desert Diamond AC for sure! Thank you Cody for being you. You are the BEST!

    Steve Schilling came out on a hot summer Sunday and fixed our A/C problems. He was professional, pleasant and we were grateful to have him. It's guys like Steve why I'll be giving Desert Diamond our business.

    Exactly what I was looking for! My A/C started blowing hot air on a Saturday summer night, so I searched online for over an hour looking through videos, company reviews, common scams, various costs, etc. For most companies, I would've had to wait 'til Monday or pay $100 for emergency service. I came across Desert Diamond and read great reviews on Google & BBB. I called @ 8am, and @ 9am Ryan showed up. He was very professional, knowledgeable, but above all -he was honest. Thanks for everything!

    Desert Diamond Mechanical was fantastic to work with. Our service Tech, Ryan, who was outstanding. Ryan had the task of attempting to diagnose a fix a lingering issue that another company could not fix over the course of the prior 6 days. Ryan methodically went through the system and fixed a very odd set of problems while discussing with us what was going on the whole way through. I would recommend Desert Diamond Mechanical for any HVAC related issues you might face.

    I would highly recommend Desert Diamond Mechanical. When I called for service I was given a time of 1-4. Ryan arrived at 12:40. He asked a few questions about my a.c. and headed up to the roof. Within 20 minutes he determined what was going on and explained my options including a service plan. Ryan was friendly, professional and informative. Fair pricing too! Thanks Ryan and Desert Diamond Mechanical
