NOAA storm reports for Fayette County show 4 hail days and 23 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 3 inches across.

Kentucky Licensing and Efficiency Rules
Kentucky is in the DOE's Southeast region, where new split central air conditioners need at least 14.3 SEER2 (13.8 SEER2 for systems of 45,000 BTU/h and up). Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in Kentucky the company should carry a state license or registration. Ask for both.
Before You Hire
- If the CO alarm goes off, get everyone outside and call 911 or the gas company before you call an HVAC company.
- Keep space heaters away from curtains and bedding, and never heat the house with a gas oven.
- Ask what the emergency fee is before the truck is sent.
