About Gra-Tac Heating & Cooling

Trusted HVAC Experts in South Central Kentucky Since 1976

Gra-Tac Heating & Cooling is a Bryant Factory Authorized HVAC company proudly serving homeowners and businesses across South Central Kentucky since 1976. Founded by John Graff and Charley Tackett, the company began when the two left their positions at the Chrysler Air-Temp factory (now the Corvette Plant) to focus on installing and servicing heating and cooling systems for their local community.

A Legacy of Growth and Local Service

What started as a small operation has grown into a trusted, full-service HVAC contractor. Today, Gra-Tac continues to expand while staying rooted in the same values it was built on—quality workmanship, reliable service, and long-term customer relationships.

Our headquarters is located at 563 Lovers Lane in Bowling Green, KY, featuring a 13,000-square-foot facility that supports our office operations, manufacturing, and storage needs.

Advanced Efficiency & Modern Technology

Energy efficiency plays a major role in long-term comfort and savings. HVAC systems are rated using SEER (Seasonal Energy Efficiency Ratio)—similar to gas mileage in a car. The higher the rating, the more efficient the system.

Older systems in the Bowling Green area typically range from 8–10 SEER, while modern systems today range from 14 to 20+ SEER, helping homeowners significantly lower their energy bills.

We stay up to date with the latest HVAC technologies to ensure you get the most efficient solutions available.

Prevent Costly Repairs with Maintenance

Routine maintenance is one of the best ways to protect your HVAC system and avoid unexpected breakdowns. Our ComfortPASS® HVAC Maintenance Program is designed to keep your system running efficiently year-round while extending its lifespan.
