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.

Stephen is highly knowledgable and really takes time to explain stuff when we got questions. He has been looking after our HVAC system for a year and we are planning to switch to DIamond Blue Air for our rental property too. Really good service and very professional. Would highly recommend to anyone looking for HVAC maintenance and repair.

Great customer service. The technician was able to come out a few hours within calling while other companies had a wait of over 2 days. Highly recommend

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!!

The Best in the Business! Stephen does great quality work and I highly recommend Diamond Blue Air!

Stephen is super knowledgeable and always try’s to do everything he can to get a system running. In the event it needs to be replaced he always try’s to give the best deal possible.
