Comfort Systems


With close to 50% of your home's utility bill going toward Heating and Cooling – HVAC Maintance, Repair, and Replacement are very important in Bowling Green and Southern Kentucky.  Gra-Tac Heating and Cooling's mission is to help Southern Kentucky Homeowners with their Heating, Cooling, Indoor Air Quality, and Energy Savings needs.


Existing Homes:  As HVAC Systems age, their efficiency, performance, and reliability decrease.  We usually see an average life expectancy of HVAC systems at 16 years.


Even if your HVAC System is still running, is it costing you more money than it's worth?


1992 – 10 SEER (Season Energy Efficiency Ratio – like Gas Mileage, but for your cooling system – the higher the number, the less electricity the system uses.) was the Federally Mandated Minimum Efficiency Standard.


2006 – 13 SEER became the Federally Mandated Minimum Efficiency Standard.  That is close to 30% less electricity being used, with some systems available that use less than 50% of the 1992 level.


2015 – 14 SEER  IS HERE, the NEW Federally Mandated Minimum Efficiency Standard.  Gra-Tac started early installing a good percentage of 14 SEER or higher systems, due to Federal, State, TVA, and other incentive programs.  13 SEER units built before December 31st, 2014 are still in the supply change, but running out fast.


As a Bryant Comfort Dealer, Gra-Tac Heating and Cooling primarily installs Bryant Air Conditioners, Gas Furnaces, and Heat Pumps.  


New Construction:  Through the years Gra-Tac Heating and Cooling has been the HVAC Contractor for many new homes.  Currently Gra-Tac works for a select few Home Builders.  We work with home builders and new homeowners to insure HVAC systems are Code Compliant, provide many years of trouble free service, and maintain comfort and energy efficiency.
