Rich from Black Diamond does outstanding work. He identified a hazardous electric issue that two other companies overlooked. The problem was resolved the same day which put our worries to rest. His expertise, work ethic and customer service are top notch!

HVAC tech was great. Wore boot covers throughout service in house. Explained service as he performed it. Felt he performed a complete service for the price. First time I've seen a tech measure gas pressures and adjust as needed as well as remove burner tubes to be cleaned and inspected. This tech was the most thorough I've seen representing Black Diamond. Feel free to contact me by phone for further information.
