HVAC Contractor License Requirements in North Carolina

Overview — hvac licensing in North Carolina

North Carolina requires a state-level hvac contractor license, issued by the North Carolina State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors (NCBEEPHFSC). The license verifies competence and consumer protection, and is required to legally bid and perform hvac work in the state. Working without one when required is typically a misdemeanor and exposes the contractor to civil penalties — and the contract becomes unenforceable in court.

License classes available

North Carolina offers 4 hvac license classes — pick based on the largest project you plan to bid:

• H-1 Heating, Group 1 (Limited). Single-family residential heating only.
• H-2 Heating, Group 2 (Restricted). Up to 350,000 BTU/hr heating.
• H-3 Heating, Group 3 (Unrestricted). All heating, any BTU.
• Air Conditioning. Companion AC license, similar tiered restrictions.
