I have used Diamond Blue for several years for my A/C service and maintenance. They are quick to come to our house when we call. The service is always thorough and complete. I like the fact that the same service men are grouped by area so we always have familiar people. Great company!

Customer Reviews
Connie Coker
I had a unique problem with one of my new units. After several visits, and contacting the manufacturer of the unit, Diamond Blue successfully traced down the issue, and repaired it, at no charge to me. They could easily have charged me labor for the trips they made, but they did not. In my opinion, this is tremendous customer service and sorely missed in our current environment.
Susan Heath
Got an appointment quickly and tech arrived on time. He promptly inspected our system and made recommendations consistent with another technician we had look at the system. Wish I had called them first.
Kim Wright

Shimail Ahmed Gillani
They came out super-fast and fixed our broken a/c ON A SUNDAY. Stephen was very professional and knowledgeable. We’ve had another service for 20 years but are switching to Diamond Blue Air.
Kenzi Larson
My wife and I own several rental houses plus our home and Diamond Blue Air and Heating have installed several new systems and have been servicing our HVAC units for several years. The reason is simple. They provide exemplary service!
I fully recommend them.
