Diamond Hearing and Cooling. They are professional and follow through. As a contractor, it is important that the job is done correctly, passes inspections, done with craftsmanship, and the job site stays tidy. Diamond Heating and Cooling has met and exceeded my expectations on a number of jobs. Job well done.

Damien was very knowledgeable and professional regarding the Bosch air handler system. He communicated his findings very well so I could understand the problem and was proactive about what to do if I had a problem again with my AC. When he left after 1 1/2 hrs my system was cooling. I was given an appointment the same afternoon I called and given a 2 hr window that tech could show up. He was 15 minutes later than estimated, but the office called to notify and get my ok for later arrival. Price was fair for work performed. I would recommend Diamond Heating and Cooling Services to my friends and was very satisfied with their service.

Very prompt, thorough, caring, and honest professional service is exactly what you get when you hire Diamond Heating & Cooling! Our air conditioning system failed on a Sunday afternoon when the summer heat reached 91°. The next morning, I called Diamond Heating & Cooling, and they immediately sent a technician to diagnose and fix the problem. Since our system was the original unit from when our home was built in 2007, a full replacement was necessary. I was given three clear replacement options to choose from. Once I made my decision, their team came out the very next day. By 5:00 p.m., we had cool air flowing through our home again! I highly recommend Diamond Heating & Cooling to anyone in need of heating or cooling services. They truly care about their customers, and you can trust they’ll take great care of you too!

I was a potential client. I arrived at the office at 8:45am on a weekday, before they opened. The workers were outside waiting for the office staff. The workers were helpful and friendly. I spoke with the secretary on the workers phone. The secretary suggested that I leave my phone# with the workers. The secretary never returned my call.
