    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

    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.

    Contacted Desert Diamond and was able to get a technician that same day! I just had an inspection for the sale of our home and it needed some minor stuff and we are moving to GA the next day. They did not try to up sell me and Nixon did a great job with shceduling me in to work with my situation. Spoke to jeff over the phone and he was very honest and knowledgeable . They sent Ryan over and he was fantastic He was Honest and he really cared about our situation. Great team work here!

    Our AC went out and the first company we tried to use ended up being a no-call no-show. I called Desert Diamond Mechanical and they had our AC up and running again less than 12 hours from the call. Ryan was incredible, a true professional. I can’t recommend him enough! I’m definitely signing up for regular maintanance plan with Desert Diamond. Great, honest company with fantastic employees. Thank you, Ryan!
