Licensing
Do you need a license in Mississippi?
Air duct cleaning is generally not a separately licensed trade in Mississippi, though a local business or privilege license typically applies if you operate your own company. Note that work touching or altering HVAC mechanical components can move into licensed mechanical territory. A NISCR certificate is a professional credential, not a government license; always verify current local and state requirements before working.

|---|---|---|
| What it is | Legal permission from a state agency to perform regulated work. | Proof you completed training and passed an exam, issued by an industry body. |
| Who issues it | Your state licensing board or agency. | NISCR — a private certification provider, not a government body. |

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. Licensing rules change and vary by city and county. Always confirm current requirements with your state licensing board before performing work.
