Do HVAC contractors need a license in Hawaii?
Yes. In Hawaii, contracting for heating, ventilating and air conditioning work requires a C-52 ventilating and air conditioning specialty contractor license from the Contractors License Board. Under the board’s rules, the C-52 classification covers fabricating, assembling and installing warm-air heating and air cooling systems, complete ventilating and air conditioning systems (including piping, non-electrical controls and building automation) and related heat pumps. Hawaii has no separate individual HVAC technician license in the statutes read; the Board of Electricians and Plumbers licenses only electricians and plumbers. This is Haw. Rev. Stat. §§ 444-7, 444-9; Haw. Admin. R. § 16-77-28.
