Best Window Cleaning in Phoenix AZ

Diamond Desert Mechanical has been TERRIFIC to work with! Steve S. took extra time and care to identify what was needed to eliminate dust issues, uneven heating and cooling in the house, and air quality concerns. He determined the most cost-effective way to achieve those results. Then David and his professional and courteous crew (Austin, Frank, Justin, Steven) did a super job of making the changes. They explained everything they were doing, made sure that my furniture was protected from any resulting dust and residue from the duct work, and did a meticulous job of cleaning up when finished. I work from home and they willingly accommodated my call schedule. They went above and beyond with extra time and effort to make sure that everything was left in better condition than when they arrived. A week after installation I had questions about the air scrubber that was installed and Steve has been just as helpful and responsive as he was before the sale was made. I wish all companies had people as professional, capable, helpful and considerate as this group of guys! Oh yes…I’ve had my system for 2 weeks now and it is delivering as expected…very little dust in the house and more even cooling. Kudos to the team!
June 2020 UPDATE: Mario performed the summer service and he was on time and did a very thorough job. He cleaned my Clean Effects filter even though it was only partially dirty...very pro-active. I continue to be satisfied with the system and with Desert Diamond Mechanical.

Ive used “Expert” five plus years after being referred to them. They have been professional, responsive and, most importantly, honest (no up-sales or phony repairs). Highly recommended!

Great company! Jesus will make sure your needs are taken care of!

The technician Skylar came to my home on time, was courteous and put footies on which I appreciated, was personable and explained everything in detail and checked my warranty to see what was covered. I was happy with the service and will use again. Thank you!

Technician Troy, 5 star service!! Highly recommend. Competent, organized, thorough. Good communicator.

Stephen showed up as scheduled, looked proper, used booties to walk in and asked about the issue. He then went on the roof to access the damaged equipment, removed it, told me the plan to get it serviced and advised me he’d call when it was corrected and ready for reinstall.

Very professional. Excellent product and service. Clean workmanship. I would highly recommend AirZona HVAC!
