Licensing
Do you need a license in Houston?
Licensing for hvac system cleaning work is set at the state and local level in Texas, and Houston 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: This trade carries a real regulatory consideration in Texas: work that involves servicing, repairing, or touching HVAC equipment, refrigerant, or mechanical systems is regulated by the Texas Department of Licensing and Regulation (TDLR), which licenses air conditioning and refrigeration contractors and technicians. Purely surface cleaning may differ from regulated service work, so you must verify current TDLR rules for your specific tasks before working. A NISCR certificate is a training credential, not a TDLR 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.
