I would give 5 stars for showing up quickly to the job.
Zero starts for honesty and cost. I did not realize how much I was going to be taken advantage of until another company did everything for a portion of the cost. I was told I did not have a gate valve and this was necessary to be installed for $700, however with ease I found the gate valve myself and asked the second plumber if that was in fact the gate valve which he agreed and said this was working perfectly.
With zero assessment of a recirculation pump I was told that it did not work at all, which the second plumber checked out and said that it was working just fine and reconnected it.
The cost of the water heater was $1000 more than I paid for all of the same equipment and install/take away.
Just do your research when using any company.

Wonderful experience with Desert Diamond from the very friendly office staff to our technician Eric. Eric was very knowledgeable. He explained everything thoroughly to my husband & I. When installing the new coil he would periodically grab my husband to show him what the old one looked like and the work he was doing, which was really nice. He cleaned everything up really well. Couldn't be happier with the service we got from everyone!!

From Popular Mechanics:
āChoosing an air conditioner sounds like it should be easy, but when you start researching different types of units, along with their various specs and installation methods, it can spiral into an overwhelming taskā¦ā
I did an engineering type analysis of the hardware from manufacturers, but HVAC pros will tell you that 80% of problem-free longevity is about installation expertise quality, follow-up and maintenance.
I researched this side of the equation, too.
I assessed and got quotes from several quality professional companies. I selected Desert Diamond Air.
I met CEO and was impressed with his leadership. Everyone down the chain was exceptional and professional in their skill set, great admin. support and product/market knowledge. Highly experienced and efficient installers and attentive after-install testing and follow-up.
Attention to detail was exemplary.
itās been about 6 months since the installation of two 4 ton units. In 114 degree heat, they are working flawlessly.
I highly recommend Desert Diamond Air in Metro Phoenix.

Tyler refused to honor the estimate I was given four mos ago for various reasons including bad mouthing another employee and bcz I wasnāt going to buy and have installed insulation. I suspect the job was too small for them. It was a 1k job (without the insulation) on invoice and he told me it would be over 2k. My impression is this company is in financial trouble and needs to hike up prices. Best wishes to them but I wouldnāt recommend.
