Does my HVAC contractor need a Kentucky license to work in Jefferson County Louisville Metro?
Yes. Only a licensed Kentucky Master HVAC Contractor can pull a permit in Jefferson County Louisville Metro. An Ohio license does not qualify. This is a frequent issue in the NKY/Cincinnati border area — always confirm your contractor holds a current Kentucky Master HVAC License before work begins.
