Licensing
Do you need a license in New Hampshire?
Cleaning is different from servicing, but in New Hampshire any work that involves opening, repairing, or modifying HVAC and mechanical equipment may require an HVAC, gas, or mechanical license or registration. Pure cleaning is often treated less strictly, but the line can blur quickly. You should verify current New Hampshire licensing and local requirements before touching any HVAC equipment. A NISCR certificate is a professional training credential and does not replace any required HVAC 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

- 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.
