Licensing
Do you need a license in Lewiston?
Licensing for hvac system cleaning work is set at the state and local level in Maine, and Lewiston may add its own business-license or registration requirements on top. Always confirm current city and county rules before bidding work. For the statewide picture: Cleaning HVAC systems is different from installing or repairing them, but in Maine the line matters: the Maine Fuel Board licenses technicians by fuel type (such as oil burner, solid fuel, and propane or natural gas), so work that involves disconnecting, servicing, or altering fuel-fired equipment can require a state fuel license. Cleaning-only services are generally not separately licensed, but you should verify current Maine Fuel Board and local requirements before touching any system.
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.
