Maine to Iowa: journeyman HVAC technician license reciprocity
Maine does not issue a statewide journeyman HVAC technician license, so there is nothing to transfer. Here is Iowa'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 (all states): Iowa exam required, licensure by verification for Iowa residents
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
Iowa has no reciprocity agreement for HVAC-refrigeration or mechanical licenses with any state, so every out-of-state journeyman follows the same path. An applicant who has established Iowa residency may apply for licensure by verification under Iowa Code 272C.12 and 481 IAC 430.4: the origin state sends a verification form directly to the board confirming the license is in good standing and was earned by meeting that state's experience requirements and exam, and the applicant provides proof of residency and a criminal history statement, but the board also requires proof of passing the applicable Iowa licensing examination and may issue a temporary license while the applicant takes it. A non-resident applies through the normal exam route: the $35 exam approval application, the Kirkwood-administered journeyperson HVAC/refrigeration exam ($119 per attempt, 75% to pass, approval valid one year), then the post-examination licensure application and a prorated three-year license fee ($180 for a full term). Exam eligibility requires either the U.S. DOL apprenticeship certificate of completion or a master-level license in the same discipline from another jurisdiction; DIAL's pages do not say that an out-of-state journeyman license alone substitutes for the DOL certificate. An Iowa resident arriving from a jurisdiction that did not license HVAC work may instead substitute three years of full-time experience in the last four years under 481 IAC 430.5. EPA Section 608 certification is federal and applies regardless of the Iowa license.
The exam fee is the amount Kirkwood Community College currently charges for every Iowa plumbing and mechanical exam; DIAL's own pages still show older figures. DIAL's published materials do not say whether an out-of-state journeyman license without a DOL apprenticeship certificate satisfies the apprenticeship requirement for a non-resident; ask the board at 866-280-1521. 481 IAC 430.4 makes the verification route residency-dependent. DIAL says to allow up to two weeks for an exam approval application to be processed.

How Iowa licenses journeyman HVAC technicians
Iowa journeyman HVAC technician · “Journeyperson HVAC-Refrigeration”
Statewide license
Issued by Iowa Plumbing and Mechanical Systems Board, Department of Inspections, Appeals, and Licensing (DIAL)
Iowa issues statewide person-held HVAC licenses through the Plumbing and Mechanical Systems Board (PMSB), now housed in the Department of Inspections, Appeals, and Licensing (DIAL); Iowa Code chapter 105 preempts all city and county HVAC licensing. The journey-level credential is the Journeyperson HVAC-Refrigeration license, which covers HVAC and refrigeration work; a broader Journeyperson Mechanical license also covers sheet metal and hydronic work and is issued to anyone who passes both the HVAC-refrigeration and hydronic journeyperson exams. A new applicant needs four years as an apprentice in a U.S. Department of Labor-registered apprenticeship and must pass the Iowa journeyperson exam (75% to pass) administered through Kirkwood Community College. Iowa has no HVAC reciprocity agreement with any state; its only reciprocity agreement is with South Dakota for plumbers. An out-of-state journeyman who moves to Iowa can use licensure by verification, but the board still requires the Iowa discipline exam; a non-resident with only a journeyman license must document the DOL apprenticeship and pass the exam, while a non-resident holding a master-level HVAC license from another jurisdiction may sit the journeyperson exam without the apprenticeship. A limited no-exam Service Technician HVAC Specialty license exists for NATE-certified or trained technicians who only service appliances from the shutoff valve onward. Licenses run on a three-year cycle ending June 30, 2029, and renewal requires eight hours of continuing education per term.
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.
