Licensing
Do you need a license in Oregon?
Air duct cleaning is generally not a licensed trade in Oregon, though a local business license or registration may be required to operate. If your work extends into HVAC equipment or mechanical systems, separate licensing rules can apply. A NISCR certificate is a professional credential, not a government license; always verify current local business and any HVAC-related requirements in Oregon.
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.
