Licensing
Do you need a license in Indiana?
Air duct cleaning is generally not a separately licensed trade in Indiana, though a local business license or registration may be required in your city or county. If your work extends to repairing or modifying HVAC equipment, separate mechanical licensing rules may apply. A NISCR certificate is a professional credential, not a government license, so verify current local requirements before operating.
| Government license | Professional certification (NISCR) | |
|---|---|---|
| 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. |
| Legally required to work? | Sometimes — it depends on your state and the specific service. | No — it is a professional credential, not a legal requirement. |

| How you get it | Apply through your state; requirements and timelines vary. | 100% online and self-paced — download your certificate the same day. |
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.
