Maine-Specific Notes (Read Before You Sign)

Trade licensing: HVAC scopes in Maine can involve state-issued trade credentials (for example, propane & natural gas, oil-burner, electrical, plumbing, and—where required—refrigeration). Display your legal business name and applicable license numbers on proposals and the contract so customers can verify status.

Permits & inspections are local: Mechanical/electrical/gas permits are issued by the city/town AHJ (e.g., Portland, Lewiston, Bangor, South Portland, Auburn, Biddeford, Sanford). Confirm permit needs, fees, and inspection timing before change-outs or new installs.

MUBEC energy/mechanical code: Maine uses the Maine Uniform Building & Energy Code (IECC/IMC-based) with local administration. If your scope triggers duct sealing/leakage testing, ventilation/HRVs, controls or commissioning, reflect responsibilities and any testing fees in the contract.

Cold climate & coastal conditions: Specify low-ambient kits/controls, condensate freeze protection, and snow/ice clearances. For coastal sites, call out stainless/galvanized hardware, protective coatings, and anchor/tie-downs where wind exposure warrants.

Cooling-off (in-home solicitation): For covered door-to-door/home solicitations, customers generally have a 3-business-day right to cancel. Attach the written notice when applicable.

Liens: Maine recognizes mechanic’s liens with timelines that vary by role/project type. Keep clear payment terms and proof of delivery for any required notices/waivers.

This page is general business guidance, not legal advice. Requirements can change—verify rules for your town and project type.
