Maine to Virginia: master HVAC technician license reciprocity

Virginia issues a statewide Master HVAC tradesman license to individuals through the Board for Contractors' Tradesmen Program at DPOR. Under 18VAC50-30-39 a first-time applicant qualifies for the PSI master exam ($125) with one year of practical experience as a licensed journeyman, three years as a Virginia residential HVAC tradesman, or nine years of verified practical experience in the trade; the application fee on the 2026 form is $171.75 including the technology fee. A current journeyman or master HVAC license from another state is itself an accepted qualification to sit the master exam, and a licensee who has held an out-of-state license for at least one year may apply through Universal License Recognition and receive the master license without the Virginia trade exam. The Board's only HVAC reciprocity agreement is an examination reciprocity agreement with the Maryland HVACR Board covering journeyman and master licenses; the electrical agreements with Alabama, DC, Kentucky, North Carolina, Ohio and West Virginia do not extend to HVAC. The master tradesman license is a personal qualification; contracting for work over $1,000 requires a separate Class A, B or C contractor business license from the same Board. EPA Section 608 certification is required federally to handle refrigerants.

Maine has no master HVAC, HVAC contractor, mechanical contractor or refrigeration license at the state or municipal level, and no general contractor license, so a business may install and service air conditioning, ductwork, ventilation and refrigeration without any state credential. The highest person-held credential in the heating trades is the Maine Fuel Board's Master Oil Burner and/or Solid Fuel Technician license ($200 plus a $21 background check, exam required, after four years licensed with at least two as a journeyman), which is the license that lets a technician work unsupervised on oil and solid-fuel burning equipment and supervise apprentices; propane and natural gas work needs the separate Propane and Natural Gas Technician license, which has no master tier. Under a 2013 memorandum of understanding between the Fuel Board and the Electricians' Examining Board, master and journeyman oil burner technicians may also wire mini-split heat pumps of 36,000 BTU or less in one- and two-family dwellings and existing multi-family dwellings with electric heat; larger units and other occupancies require a licensed electrician, and refrigerant handling requires federal EPA Section 608 certification. A master HVAC licensee arriving from another state gains nothing from that license in Maine: no Maine agency recognizes it, no reciprocity exists for any Fuel Board license, and the Fuel Board's rules only credit documented out-of-state employment toward the master oil burner qualifications before the applicant sits the Maine exam. A statutory licensure-by-endorsement route (32 M.R.S. s. 18142-A and 10 M.R.S. s. 8003-H) applies to Fuel Board licenses in principle, but the board has not published an endorsement procedure or a list of equivalent states.
