"Craig did the inspection and quoted me different AC units. He understood my needs and budget, and provided the best quote between 3 companies for same models. He answered calls and text when I had questions. Brody and Joshua did the install, including a new thermostat and new vent."
"I called Desert Diamond after a home inspection showed heating unit not working correctly. They got someone out the same day. Phillip was very responsive and professional. He let me know when he arrived since the home was empty, and promptly notified me with his findings."
"In the past, we’ve always had to use different AC companies due to poor quality service, but this is now our second year with Desert Diamond AC and the difference has been night and day. Both Daniel C and the prior service technicians we had have been excellent."
