Licensing
Do you need a license in New Hampshire?
Unlike simple vent cleaning, dryer vent installation in New Hampshire can fall under contractor or mechanical codes, particularly when venting passes through walls, roofs, or interacts with gas appliances. Permits and a local business registration may also apply. You should verify current New Hampshire building, mechanical, and municipal requirements before performing installation work. A NISCR certificate documents professional training and does not replace any required contractor or mechanical license.
| 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.
