Oil heating and solid fuel work requires Oil Burner Technician licensing; propane and natural gas work requires Propane and Natural Gas (P&G) licensing.

Out-of-State Reciprocity
VerifiedDoes Not Accept Out-of-State Credentials
Reciprocity Type
No formal reciprocity
Transfer Details
Maine does NOT have formal reciprocity agreements for HVAC-related (Fuel Board) licenses. Out-of-state applicants must present satisfactory evidence of experience to the Board and meet Maine's licensing requirements.
Additional Requirements for Transfer
HVAC license reciprocity varies significantly by state. Some states offer endorsement for experienced technicians, while others require passing the state exam regardless of prior credentials.
Maine does NOT issue a dedicated 'HVAC' license. Instead, HVAC work is regulated by FUEL TYPE through the Maine Fuel Board under OPOR/DPFR. Oil heating and solid fuel work requires Oil Burner Technician licensing (Apprentice → Journeyman → Master track), while propane and natural gas work requires separate P&G licensing (Helper → Technician track with endorsements). There is no single unified HVAC credential. Technicians working across fuel types must hold multiple licenses. The Fuel Board also issues several limited/specialty licenses including Limited Wood Pellet Technician, Limited Tank Installer, and Limited Energy Auditor licenses.
IMPORTANT: Maine does NOT issue a dedicated 'HVAC' license. HVAC work is regulated by FUEL TYPE through the Maine Fuel Board. Oil heating requires Oil Burner Technician licensing; propane/natural gas work requires P&G licensing. Technicians working on both fuel types need both sets of licenses.
The Maine Fuel Board is under the Office of Professional and Occupational Regulation (OPOR), within the Department of Professional and Financial Regulation (DPFR).
All license applications require a $21 background check fee in addition to the license fee.
EPA Section 608 certification is a separate federal requirement for anyone handling refrigerants — this is not issued by the Maine Fuel Board.
An electrical license from the Maine Electricians' Examining Board may be required for HVAC wiring work.
No state-level general contractor license exists in Maine; local business licenses are required per municipality.
Workers' compensation insurance is required if employing workers.
Home Improvement Contractor registration under Title 10 §§1486-1490 may apply for residential HVAC work.
Maine does NOT have formal reciprocity agreements for Fuel Board licenses. Out-of-state applicants must present satisfactory evidence of experience to the Board.
P&G Technician endorsement areas include: Delivery Technician, Plant Operator, Tank Setter & Outside Piping, Appliance Connection & Service (up to 500K BTU), and Large Equipment Connection & Service (over 500K BTU). Adding endorsements costs $0 but requires passing an additional exam.
Temporary Permit for Plant Operator/Delivery Technician is a 1-year non-renewable permit (one permit per 3 years); must register within 90 days of hire and become licensed within 1 year.
Only the Master Oil Burner and/or Solid Fuel Technician license requires continuing education (8 hours per biennial renewal).
