How Kentucky licenses HVAC work
HVAC contractors are licensed by the state.
Who licenses: Kentucky Department of Housing, Buildings and Construction (Division of HVAC)
License types: Master HVAC Contractor, Journeyman HVAC Mechanic, HVAC Apprentice Registration.
Companies: A company or individual must hold a Master HVAC Contractor license to advertise or practice HVAC contracting (installation, maintenance, alteration, remodeling or repair of heating, ventilation, hydronic, burner-service or cooling systems) under KRS 198B.650-198B.689 and 815 KAR 8:010. KRS 198B.674 exempts a few groups, such as homeowners working on their own occupied property and full-time maintenance staff doing routine maintenance.
Local rules: The state also runs HVAC permits and inspections for new installations, and its HVAC permitting page says 17 local programs hold their own HVAC jurisdiction, so permits may go through the local authority instead.
Check a license: dhbc.ky.gov
Search the contractor's name on the state license search (choose Division of HVAC, license type Master HVAC Contractor) and confirm the license is active before signing.
Federal rule: in every state, technicians who handle refrigerant must hold EPA Section 608 certification, whatever the state or city requires.

Before you hire
Ask for the license number and check it on the official lookup where one exists. Ask for proof of insurance and a written, itemized estimate, and ask who pulls the permit if the job needs one – a new furnace, heat pump or air conditioner usually does.
