About David Gray - Electrical, Plumbing, Heating & Air
David Gray - Electrical, Plumbing, Heating & Air has served St. Augustine area homeowners since 2001, delivering licensed expertise across three trades under one roof. The company holds active state contractor licenses and maintains an A+ rating with the Better Business Bureau, supported by 251 verified customer reviews averaging 4.9 stars. Operating around the clock seven days a week, their dispatch team serves residential clients throughout St. Augustine, Jacksonville, and Palm Coast, responding to emergency calls for plumbing failures, HVAC breakdowns, and electrical outages that threaten home comfort and safety.
What distinguishes David Gray from neighboring contractors is their manufacturer-certified partnerships and specialized service lines. As a Generac authorized dealer and installer, they provide whole-home backup generator installations with factory-backed preventative maintenance contracts. Their indoor air quality division installs advanced air scrubbers and whole-house filtration systems designed for Florida's humid climate, addressing mold spores and allergen concerns common to coastal properties. The company also maintains a dedicated historic homes division familiar with restoring plumbing and electrical systems in pre-1960s St. Augustine residences while meeting current code requirements.
Customer reviews consistently name technicians who arrive prepared and communicate clearly. James responded to an evening AC emergency and stayed until the system ran flawlessly, cleaning coils and refrigerant lines. Adam, called out for an electrical panel upgrade, presented pricing before beginning work and left the workspace immaculate. Reviewers note that same-day service often comes with a higher price tag, but technicians complete jobs efficiently, one homeowner reported a kitchen outlet repair finished in 15 minutes.
