Licensing
Do you need a license in South Carolina?
Air duct cleaning is generally not a separately licensed trade in South Carolina, though you will typically need a local business license to operate. Note that cleaning ducts is distinct from servicing HVAC equipment, which can trigger mechanical-licensing rules. A NISCR certificate is a professional credential, not a government license, so verify current South Carolina local requirements before offering services.
A NISCR Certificate of Completion confirms completion of NISCR training and examination. It is a professional credential, not a government license. Where local law requires a license to perform a service, the technician is responsible for obtaining it.
