Coolray Heating & Air Conditioning stands as one of the most established HVAC brands in the Atlanta metro, with 60 years of service history and more than 10,700 Google reviews at 4.8 stars. Founded in the 1960s, Coolray has grown from its roots in North Atlanta into a comprehensive home services company offering HVAC, plumbing, electrical, water treatment, and insulation — a multi-trade platform that handles most of a homeowner's systems under one roof.

The company's signature differentiator is the Lifetime Parts and Labor Warranty: eligible customers receive $0 repair fees for life on covered systems. This is an unusually strong commitment in an industry where service contracts often limit liability, and it appears directly in customer reviews as a primary reason for choosing Coolray over competitors. The warranty removes the anxiety of ongoing repair costs and creates a long-term relationship with the company.

Service offerings span AC repair, AC maintenance, AC installation, heating, plumbing, electrical, water treatment, and insulation. The maintenance plan provides systematic preventive care to keep systems running efficiently and extend equipment life. Coolray serves the entire Atlanta metro region with a field team sized to match their substantial review volume.

Customer reviews consistently highlight technicians named Jeremy and Wes as standouts — professional, methodical in their diagnostic approach, and clear in their communication. Multiple reviewers mention having used Coolray for years and returning specifically because of the warranty program and consistent technician quality. The pricing is described as competitive, and reviewers note that Coolray teams bring genuine expertise to complex multi-system service calls.

For Marietta, GA homeowners seeking a 60-year-old, fully integrated home services provider with warranty coverage that eliminates future repair costs, Coolray is one of the few operators at that scale and longevity in the Atlanta market.
