About Us

With over 42 years of experience in the HVAC industry, we transitioned to HERS Rating in 2005, and our expertise in HERS Title 24 sets us apart. Coast Energy proudly offers essential Title 24 forms and HERS testing to homeowners, HVAC installers, and builders. We specialize in reading CF-1R forms for new construction and alteration projects, and our team is highly trained in the Energy Code. We’re dedicated to providing thorough testing and support throughout every stage of a residential project. As part of our ongoing growth, Angela Gregory will soon earn her Certified Energy Analyst credential, while Don DeAngelis continues offering trusted HERS testing. Shelly DeAngelis handles scheduling and accounting, and our newest team member Edie Gregory who assists with processing. Together, we are a small but "MIGHTY" team.
