Minnesota to Maryland: journeyman HVAC technician license reciprocity
Minnesota 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.

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 Minnesota has nothing to transfer
Minnesota journeyman HVAC technician
Licensed by cities and counties
Minnesota has no state HVAC or refrigeration technician license at any level. The Department of Labor and Industry (DLI) states that there is 'no state license requirement for individual employees of mechanical contractors' and no state license for mechanical contractors either; the only statewide requirement is the $25,000 mechanical contractor bond that a business must file with DLI under Minn. Stat. 326B.197 before contracting for gas, heating, ventilation, cooling, air conditioning, fuel burning or refrigeration work. Journeyman-level licensing exists only where a city requires it: Minneapolis and Saint Paul both require a journeyman Certificate of Competency (Warm Air/Ventilation or Refrigeration) to work in the trade, issued after four years of experience and an exam, and Saint Paul additionally registers trade workers; Bloomington, Rochester and Duluth license contractors or master installers but not journeymen. An out-of-state journeyman HVAC license has no state-level recognition in Minnesota and none of these cities publish a path that accepts it; the only local reciprocity is between Minneapolis and Saint Paul. Anyone who handles refrigerants must also hold federal EPA Section 608 certification, which is not a state license.
How local licensing works in Minnesota
How local licensing works. Minnesota licenses neither HVAC contractors nor HVAC workers at the state level. DLI's only role is the $25,000 mechanical contractor bond (Minn. Stat. 326B.197; $100 filing fee for two years), which the statute makes 'in lieu of all other bonds to any political subdivision'. Everything about who may personally do HVAC work comes from city ordinances, and most Minnesota cities require nothing of employees.
Minneapolis. Under Minneapolis Code Chapter 278, 'masters and journeymen' in the refrigeration and warm air/ventilation trades (as well as fuel gas fitting and steam and hot water) 'need the card in order to perform work in Minneapolis'. A Journeyman Warm Air Ventilation or Journeyman Refrigeration Certificate of Competency requires four years (1,600 hours per year) of on-the-job experience plus four years (576 hours) of trade-related education, or a state-approved apprenticeship; the Building Official approves eligibility (no application fee), the ICC exam is taken at Pearson VUE (100-question Journeyman Warm Air Ventilation exam or 70-question Journeyman Refrigeration exam, 70% to pass, $115), and the card costs $30 per trade. A failed exam requires a 60-day wait; scores are valid one year. Minneapolis has reciprocity only with Saint Paul: a Saint Paul card holder sends copies of the card and $30 per trade.
Saint Paul. The Department of Safety and Inspections requires Certificates of Competency (master and/or journeyman) in Warm Air/Ventilation, Refrigeration, Gas Burner, Oil Burner and Steam Fitting/Hot Water. Warm Air/Ventilation exams are held twice a year (January and July); refrigeration and burner candidates arrange testing through the Senior Mechanical Inspector. Journeymen must also carry an annual trade worker registration ($37 per trade for 0-4 years registered, $70 for 5-6 years, $59 for 7 or more). Reciprocal cards are issued on a current Minneapolis card for $24 per trade (Refrigeration at both levels; Warm Air and Ventilation at master level only).
Bloomington. Licenses mechanical contractors (HVAC, gas installer, hot water/steam, oil burner, refrigeration) on the strength of a Minneapolis or Saint Paul competency card or Bloomington's own $35 open-book mechanical test; no journeyman credential.
Rochester. Licenses HVAC Contractors ($125 per year) and individual HVAC Master Installers ($60 per year plus a $25 certificate of competency per area); no journeyman credential.
Duluth. Issues no mechanical license; a DLI-bonded mechanical contractor pulls the permit.
Out-of-state holders. None of these cities publish a reciprocity, endorsement or exam-waiver route for an HVAC license from another state. A journeyman arriving in Minnesota needs no credential to work for a bonded contractor outside Minneapolis and Saint Paul; inside those cities they should expect to document four years of experience and education and pass the city exam (or obtain one city's card and reciprocate to the other).
