Do HVAC contractors need a license in South Carolina?

Yes. In South Carolina, heating and air conditioning contracting needs a state license: a mechanical contractor license in the air conditioning, heating or packaged equipment subclassification for jobs costing more than $10,000, or a residential specialty contractor license for residential heating and air conditioning work over $500. The mechanical subclassifications cover air conditioning systems, steam and hot water heating systems, and packaged heating and air conditioning equipment including ventilation and duct work. Residential heating and air conditioning installers and repairers must pass the required examination to be issued a specialty contractor license by the Residential Builders Commission. This is S.C. Code §§ 40-11-30, 40-11-410, 40-59-20, 40-59-30.
