Licensing
Do you need a license in Knoxville?
Licensing for hvac system cleaning work is set at the state and local level in Tennessee, and Knoxville 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 close to a regulated line in Tennessee. Surface cleaning may not require a license, but once work involves opening, servicing, or repairing HVAC and mechanical equipment, Tennessee mechanical contractor licensing can apply, and refrigerant handling carries federal certification requirements. A local business license also generally applies. Your NISCR certificate is a professional credential, not a government license. Always verify current HVAC and mechanical licensing requirements with the Tennessee Board for Licensing Contractors and your local jurisdiction before performing regulated 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

- 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.
