Licensing
Do you need a license in South Carolina?
This is an important distinction in South Carolina: cleaning is generally unlicensed, but touching, opening, or servicing HVAC/mechanical equipment can require an HVAC or mechanical contractor license under state and local rules. If your work goes beyond surface cleaning into mechanical service, refrigerant, or electrical connections, licensing likely applies. A NISCR certificate is a professional credential, not a government license, so verify current South Carolina HVAC/mechanical licensing requirements before working on equipment.
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.

Curriculum
What you’ll learn
- Clean and rinse evaporator and condenser coils without bending fins or damaging the coil, using the correct foaming and no-rinse cleaners for each coil type.
- Disassemble, clean, and rebalance blower wheels and motor assemblies to remove caked debris that chokes airflow and wastes energy.
- Service condensate drain pans and lines — clearing clogs, treating biofilm, and verifying proper slope and drainage to prevent overflow and microbial growth.
- Open, inspect, and clean air-handler interiors and plenums, including interior insulation surfaces, following containment and source-removal standards.
- Set up negative-air containment and HEPA collection so dislodged debris is captured rather than spread through the occupied space.
- Identify and document microbial contamination, biofilm, and rust, and know when to refer remediation beyond routine cleaning.
