Do HVAC contractors need a license in Kentucky?

Yes. In Kentucky, nobody may practice heating, ventilation and air conditioning contracting without meeting the state HVAC licensing law, and the master HVAC contractor license from the Department of Housing, Buildings and Construction is what entitles a person to practice HVAC contracting and obtain the permits. Journeyman and apprentice HVAC mechanics hold their own license or certificate. The law does not apply to an individual owner doing HVAC work on property the individual owns and occupies, to work on residential window air conditioning units, or to a full-time maintenance person doing routine maintenance as part of the job. This is KRS 198B.650, 198B.656, 198B.674.
