Licensing
Do you need a license in Louisiana?
Cleaning HVAC systems can be sensitive in Louisiana because touching, repairing, or modifying mechanical equipment may fall under state HVAC or mechanical contractor licensing, while surface cleaning may not. The line depends on the exact work performed, so verify current Louisiana State Licensing Board for Contractors and local mechanical-licensing requirements before servicing equipment. The NISCR certificate documents training and is not a government or mechanical 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.
