Hear From Our Satisfied Customers

I used two contractors from home warranty for the heating issue. One said I need to change the zone panel without checking anything. The second guy said it is an airflow issue and he can't help.Stephen from Diamond Blue Air is excellent in explaining about the airflow issue and he fixed it in no time. I will use them again in the future.

We are currently in the process of evaluating the various quotes from HVAC companies so I cannot comment on the end work just yet. However, I want to express my extreme gratitude to Diamond Blue Air for promptly returning my call and inquiry, as well as being on time (actually a little early). Mainly, I want to thank the tech, Stephen, who went through all our concerns, provided multiple different options and ideas to help save us money and headaches in the future. He went out of his way to go through every aspect of our complex commercial system and hear our concerns. He was professional and based on our time with him, would recommend this business to all!!

Stephen showed up promptly with great communication. Really took the time to connect with us as a customer, and listen to where our concerns were. Stephen took the time to inspect our entire A/C unit, took pictures of all areas afterwards and did all sealing and maintenance needed. Highly recommend using this company.

Great experience with Roy and his installation team who installed 2 brand new Lennox HVAC systems in my home. All three men were polite and expedient. They installed and got the main system up and running on day one, and the upstairs unit on day two. They took care of everything from start to finish. In addition both systems came with smart thermostats, in this case ECOBEE4, that have incredible features. I would highly recommend contacting Roy with Blue Diamond Air for any HVAC concerns including getting a new system.
