Licensing
Do you need a license in Colorado?
This is where Colorado readers must be careful: cleaning HVAC surfaces is one thing, but touching, repairing, or modifying HVAC and mechanical equipment can require an HVAC or mechanical license, and several Colorado jurisdictions regulate mechanical contractors at the local level. Refrigerant handling carries additional federal EPA certification. Always verify current requirements with DORA, your local building department, and applicable mechanical-licensing authorities before working. A NISCR certificate documents professional cleaning training, not a license to perform regulated mechanical work.
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.
