Licensing
Do you need a license in Ohio?
This is an important one for Ohio: cleaning HVAC equipment can cross into work that requires a state mechanical or HVAC contractor license. Ohio's Construction Industry Licensing Board issues HVAC contractor licenses, and a state license is generally required for commercial HVAC work, with cities like Columbus and Cleveland often requiring it even for residential jobs. Where your cleaning touches refrigerant, electrical, or mechanical components, licensing rules likely apply. Always verify current state and local requirements before working. A NISCR certificate is a professional training credential, not a government HVAC license.
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.
