Maine to Maryland: journeyman HVAC technician license reciprocity
Maine does not issue a statewide journeyman HVAC technician license, so there is nothing to transfer. Here is Maryland's standard path for out-of-state applicants.
Your origin state does not issue a statewide license at this level, so there is no license to transfer. The destination's standard out-of-state path is shown; expect to meet it in full.
Reference only, not legal advice. Rules change; confirm with the licensing board before you apply. Full disclaimer.
Out-of-state journeyman without a reciprocal agreement
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
A journeyman licensed in a state other than Delaware or Virginia must qualify for an original Maryland journeyman license by examination; the Board's FAQ says reciprocal licensing is available only where an agreement exists. The statutory route is 4 years as a licensed apprentice with 6,000 hours of training under a licensed contractor, but Bus. Reg. §9A-302(g) lets the Board credit up to 6 years of HVACR work experience that does not fit that pattern when it provided comparable experience and the shortfall was not the applicant's fault, and up to 3 years of formal HVACR study, so documented out-of-state journeyman experience can be submitted to PSI (the Board's testing vendor, which reviews eligibility) in place of a Maryland apprenticeship. The applicant then passes the open-book PSI journeyman exam with 70% ($150), registers the license with the Department and pays the $25 license fee. Bus. Reg. §9A-305 also allows the Board, by majority vote, to waive the exam for a licensee of any state that waives its exam for Maryland licensees to a similar extent, but the Board has published that waiver only for Delaware and Virginia. There is no separate law or business exam.
The Board's requirements page and Bus. Reg. §9A-302(e) require 4 years as a licensed apprentice with 6,000 hours; the PSI bulletin (updated 9/1/2024) still describes a 3-year/1,875-hour apprentice standard and a Board-approved route for 'at least three years of qualifying experience'. The Board's published materials do not say how PSI and the Board apply §9A-302(g) credit to experience gained under an out-of-state license; ask the Board (410-230-6196) before applying. The HVACR Journeyman exam has 100 questions in 240 minutes; the restricted journeyman exams are 40-50 questions in 90-120 minutes.

How Maryland licenses journeyman HVAC technicians
Maryland journeyman HVAC technician · “HVACR Journeyman”
Statewide license
Maryland issues a statewide HVACR Journeyman license through the Board of Heating, Ventilation, Air Conditioning and Refrigeration Contractors in the Department of Labor, a different board from the State Board of Electricians. Everyone who provides or assists in providing heating, ventilation, air-conditioning or refrigeration services in Maryland must hold a Board license (apprentice, journeyman, journeyman restricted, limited, master restricted or master); the journeyman license authorizes HVACR work under the direction and control of a licensed contractor, and a journeyman restricted license covers a single area (forced air, hydronic, ventilation, air conditioning or refrigeration). A new journeyman must have held a Maryland apprentice license for at least 4 years with at least 6,000 hours of training under a licensed contractor and pass the PSI-administered journeyman exam with 70% ($150 exam fee, $25 license fee); graduates of a Maryland Apprenticeship and Training Council program are licensed without the exam. The Board has reciprocal agreements only with Delaware and Virginia, under which a qualifying journeyman is licensed without the Maryland exam. Licenses run to October 1 of odd-numbered years and renew for 2-year terms; Anne Arundel and Prince George's Counties also require a county HVACR license.
Why Maine has nothing to transfer
Maine journeyman HVAC technician
No individual license at this level
Issued by No HVAC licensing authority (Maine Fuel Board licenses fuel technicians only)
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.
