Maine to Arkansas: journeyman HVAC technician license reciprocity

Arkansas has no journeyman HVAC license; the person-held credential for an employee who performs heating, air conditioning or refrigeration work is the HVACR Registrant registration issued by the Department of Labor and Licensing. Ark. Code §17-33-303(c) lets an individual perform HVACR work under a Class A, B, D or E license holder by registering with the department; the $25 annual registration fee is the license holder's responsibility, and every licensee must make sure each HVACR employee holds a current registration or license. Registration is not credential-based: the application asks for no experience, education, exam or prior license and is tied to the employer's designated license holder, so it must be obtained by everyone regardless of any journeyman or technician license held in another state, and no out-of-state license shortens or replaces it. A registrant may work only for an HVACR licensee; under §17-33-104 a registered individual cannot be required to obtain any city or county license, though local permits and inspections apply. The Board has no reciprocal agreements with any state at any level. Federal EPA Section 608 certification is separately required of anyone who handles refrigerants.

Maine does not issue a journeyman HVAC, air conditioning or refrigeration license, and no Maine city or town was found to do so either; the Office of Professional and Occupational Regulation's list of licensed professions contains no HVAC or mechanical trade. What Maine does license is the fuel side of heating: the Maine Fuel Board issues Journeyman Oil Burner and/or Solid Fuel Technician licenses ($100 plus a $21 background check, exam required, after one year as a licensed apprentice or 160 hours of approved coursework plus six months of apprenticeship) and Propane and Natural Gas Technician licenses ($100 plus $21, board-approved training plus a Fuel Board exam), and anyone who installs or services oil, propane, natural gas or solid-fuel burning equipment must hold one. Ductwork, air conditioning, refrigeration and the mechanical parts of a heat pump need no state license; the electrical connection of a heat pump must be made by a licensed electrician (or, for mini-splits of 36,000 BTU or less in one- and two-family dwellings, by a licensed oil burner technician under a 2013 memorandum of understanding), and the installer needs federal EPA Section 608 refrigerant certification if the system is not factory charged. An out-of-state journeyman HVAC license therefore has nothing to transfer to; the technician may work for any employer without a Maine credential, but must obtain the relevant Fuel Board license before touching a furnace, boiler or gas appliance, and Fuel Board rules give out-of-state applicants no exam waiver, only credit for documented employment as a technician (a statutory endorsement process under 10 M.R.S. s. 8003-H exists but the board has not published a procedure). EPA Section 608 certification is federal and required everywhere for refrigerant handling.
