Maine to Idaho: journeyman HVAC technician license reciprocity

Idaho issues a statewide HVAC Journeyman certificate of competency through the Heating, Ventilation and Air Conditioning Board at the Division of Occupational and Professional Licenses (DOPL); a journeyman works in the employ and under the direction of a licensed HVAC contractor. A new applicant pays a $35 application fee and qualifies either by completing 576 hours of instruction at a board-approved apprenticeship program plus 8,000 hours of supervised installation work while registered as an Idaho apprentice, or by documenting 16,000 hours of supervised HVAC installation work, and in both cases must pass the PSI-administered journeyman exam ($75) within a year of applying; the license costs $150 and renews for $75 every three years. DOPL also issues Specialty Journeyman and Limited Heating Specialty Journeyman certificates for hearth appliances, oil furnaces and gas piping. The HVAC board's FAQ states that Idaho has no reciprocal licensing agreement for HVAC. An out-of-state journeyman can instead use Idaho's universal licensure statute (Idaho Code 67-9409), under which the board must license a person holding a current, unrestricted license elsewhere who demonstrates competency, but may still require the Idaho exam; the HVAC application form itself offers no endorsement box, so applicants should contact DOPL before filing. EPA Section 608 certification is required nationwide to handle 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.
