Licensing
Do you need a license in New Hampshire?
Air duct cleaning is generally not a licensed trade in New Hampshire, though most towns and cities expect a local business license or registration to operate. If your work extends to repairing or altering HVAC equipment rather than just cleaning ducts, separate mechanical or trade requirements could apply. Always verify current local and state rules for your scope. A NISCR certificate documents professional training and is not a government license.
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.
Local demand

Pollen-heavy springs and wood-stove particulates add to indoor air-quality concerns for families across Manchester, Nashua, and Concord.
