Do HVAC contractors need a license in Florida?
Yes. In Florida, engaging in the business of air-conditioning or mechanical contracting (central air-conditioning, refrigeration, heating and ventilating systems) requires a state certification or registration from the Department of Business and Professional Regulation. The statute defines Class A air-conditioning contractors (unlimited), Class B air-conditioning contractors (limited to 25 tons of cooling and 500,000 Btu of heating in any one system), Class C air-conditioning contractors (servicing only, not issued to new applicants since October 1, 1988) and mechanical contractors. A certified contractor may contract anywhere in the state; a registered contractor only in the jurisdiction whose competency requirements were met. This is Fla. Stat. §§ 489.105, 489.113.
