Licensing
Do you need a license in Columbia?
Licensing for hvac system cleaning work is set at the state and local level in Maryland, and Columbia may add its own business-license or registration requirements on top. Always confirm current city and county rules before bidding work. For the statewide picture: HVAC system cleaning sits closer to regulated territory than basic duct cleaning, because touching, opening, or servicing HVAC equipment can require an HVAC or mechanical license in Maryland depending on the work performed. Cleaning that stays surface-level may not, but anything involving refrigerant, electrical, or mechanical service generally does. Your NISCR HSC certificate is a professional credential, not a government license, so verify Maryland HVAC/mechanical licensing requirements before performing equipment-level 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

- Disassemble, clean, and rebalance blower wheels and motor assemblies to remove caked debris that chokes airflow and wastes energy.

- 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.
