Licensing
Do you need a license in Alabama?
Air duct cleaning is generally not a separately licensed trade in Alabama, though you will typically need a local business license to operate, and you should avoid work that crosses into HVAC equipment service that may require a mechanical license. This certificate documents training, not government licensure, so verify current city, county, and state requirements for the services you provide.
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.
