Minnesota to Oklahoma: journeyman HVAC technician license reciprocity
Minnesota does not issue a statewide journeyman HVAC technician license, so there is nothing to transfer. Here is Oklahoma'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 HVAC journeyman (all states; no published reciprocity partners)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
CIB publishes no mechanical reciprocity partner list, so every out-of-state HVAC or refrigeration journeyman uses the same route. Under OAC 158:50-9-4.1 a journeyman from a state without a reciprocal agreement (or from a jurisdiction with only local licensing) may request exam equivalency; if the Board has previously approved that jurisdiction's exam as substantially similar, the Oklahoma journeyman exam is waived on a certified letter from the home jurisdiction showing a current license in good standing, the license category, an exam score of 70% or higher and no pending discipline. CIB does not publish which jurisdictions' exams are approved. Otherwise the applicant files the Application for Mechanical Examination with notarized experience affidavits and a copy of the out-of-state license, documents three years of verifiable experience in the category (out-of-state experience counts if lawfully obtained), pays $75, and must pass the HVAC/R journeyman exam through PSI. A current out-of-state license in the same classification may also expedite processing under OAC 158:50-9-1(b)(1)(I). Federal EPA Section 608 certification is required separately to handle refrigerants.
The rules mention that the Board 'may enter into a reciprocity agreement with another state' with substantially equivalent requirements (OAC 158:50-9-6(d)), but no signed mechanical agreement, partner state or reciprocity form appears on any CIB page, unlike the electrical and plumbing programs; some third-party sites claim HVAC reciprocity with Texas, Arkansas, Kansas or New Mexico, but no CIB page lists such an agreement (Kansas and New Mexico do not issue a statewide HVAC journeyman license). The CIB mechanical pages do not mention EPA certification; the federal requirement applies regardless.

How Oklahoma licenses journeyman HVAC technicians
Oklahoma journeyman HVAC technician · “Mechanical Journeyman (HVAC/R Unlimited or Limited)”
Statewide license
Issued by Oklahoma Construction Industries Board (CIB), Mechanical Division
Oklahoma issues statewide mechanical journeyman licenses through the Construction Industries Board (CIB) under the Mechanical Licensing Act. The HVAC/R Unlimited category has no size limit; HVAC/R Limited covers cooling up to 25 tons and heating up to 500,000 Btu/h per appliance; both include refrigeration, sheet metal, natural gas and related process piping, and stand-alone Refrigeration, Sheet Metal, Natural Gas Piping and Process Piping journeyman categories also exist. A new applicant needs three years (6,000 hours) of verifiable experience in the category while employed by a licensed mechanical contractor, with approved trade-school hours substituting for up to two years, pays $75 ($25 application plus $50 initial license) and passes the PSI exam with 70% ($92 per portion). CIB's rules allow written reciprocity agreements and a case-by-case exam equivalency for licensees of jurisdictions whose exam the Board has approved, but CIB publishes no list of mechanical reciprocity partners or approved jurisdictions. Journeymen must work under a licensed mechanical contractor, renew annually in their birth month, and complete six hours of continuing education every 36 months.
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).
