Minnesota to Michigan: master HVAC technician license reciprocity
Minnesota does not issue a statewide master HVAC technician license, so there is nothing to transfer. Here is Michigan'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 or mechanical contractor (all states; Michigan has no reciprocity)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
Michigan has no reciprocity agreement with any state and no endorsement route; LARA's Out-of-State License Verification form states that Michigan 'does not reciprocate with any other state for licensing' and that the applicant is 'required to take and pass an examination'. An out-of-state licensee files the standard Application for Mechanical Contractor Examination & Licensing with the $300 fee, selects the classifications wanted, and documents 3 years or 6,000 hours of experience in each classification with statements signed under penalty of perjury by each present or former mechanical contractor employer; applicants with out-of-state experience must be approved by LARA before PSI will let them schedule. The applicant then passes each classification exam at PSI within one year of eligibility (HVAC Equipment: 150 questions, open book, 3 hours, $100; other classifications: 55 questions, 60 minutes, $50; 75% to pass, unlimited retakes within the year). There is no separate law or business exam, but every exam includes questions on the Skilled Trades Regulation Act and the Stille-DeRossett-Hale Single State Construction Code Act. The license runs on a 3-year cycle expiring August 31 and the fee is prorated for mid-cycle applicants.
Whether experience documented by an out-of-state employer that is not a Michigan 'contractor of record' is accepted as the 'equivalent experience acceptable to the board' under MCL 339.5807(1)(a) is decided by LARA case by case; the out-of-state form only says such applicants must be approved to sit. Exam fees listed are per classification; an applicant seeking several classifications pays each.

How Michigan licenses master HVAC technicians
Michigan master HVAC technician · “Mechanical Contractor (classified: HVAC Equipment, Refrigeration, Ductwork, Heating/Refrigeration Service, etc.)”
Statewide license
Michigan's HVAC credential is the Mechanical Contractor license issued by LARA's Bureau of Construction Codes under Article 8 of the Skilled Trades Regulation Act (2016 PA 407). Although called a contractor license, it is issued to an individual who qualifies by examination, so this file treats it as the master level: a business performs mechanical work by designating a licensed individual as its contractor of record (MCL 339.5809, 339.5815). The license is classified; an HVAC business typically holds HVAC Equipment (which includes ductwork and gas piping), Refrigeration and the heating and refrigeration/air conditioning service classifications. For each classification the applicant documents 3 years or 6,000 hours of experience with statements signed under penalty of perjury by each employing contractor of record (a 2-year HVAC program may be credited up to 1 year or 2,000 hours), is approved by LARA, and passes the PSI exam for that classification (75% to pass; the HVAC Equipment exam is 150 questions, open book, 3 hours, $100; other classification exams are 55 questions, 60 minutes, $50). The license fee is $300 for the 3-year cycle ($100 per year, prorated), licenses expire August 31 every third year, and municipalities may not impose their own licensing (MCL 339.5811). Michigan has no reciprocity with any state and no licensure by endorsement: LARA's out-of-state form states that Michigan 'does not reciprocate with any other state for licensing' and that out-of-state applicants must be approved to sit for the examination, so an out-of-state HVAC or mechanical contractor's experience counts toward eligibility but the Michigan exams must be passed. Federal EPA Section 608 certification is separately required to handle refrigerants.
Why Minnesota has nothing to transfer
Minnesota master HVAC technician
Licensed by cities and counties
Minnesota issues no master HVAC, master refrigeration or HVAC contractor license. The only statewide requirement is the $25,000 mechanical contractor bond that a business files with the Department of Labor and Industry (DLI) under Minn. Stat. 326B.197 ($100 filing fee, valid two years) before contracting for gas, heating, ventilation, cooling, air conditioning, fuel burning or refrigeration work; DLI states that there is no state license for mechanical contractors or their employees and that cities may require licensure or a competency card. The master-level credential therefore exists only at the city level: Minneapolis issues Master Warm Air Ventilation and Master Refrigeration Certificates of Competency (four years of experience and education plus an ICC exam) and requires a master card holder behind each HVAC Class A or Refrigeration Systems Installer contractor license; Saint Paul issues Master Warm Air, Ventilation and Refrigeration competency cards and requires one for each Warm Air/Ventilation business trade license; Rochester licenses individual HVAC Master Installers after a city certificate of competency; Bloomington licenses mechanical contractors on a Minneapolis or Saint Paul card or its own test. An out-of-state master HVAC or mechanical contractor license has no state-level recognition and none of these cities publish a path that accepts it; Minneapolis and Saint Paul recognize each other's master cards. Federal EPA Section 608 certification is separately required of anyone handling refrigerants.
How local licensing works in Minnesota
How local licensing works. Minnesota has no state mechanical or HVAC license and no state HVAC board. Under Minn. Stat. 326B.197 a business contracting for gas, heating, ventilation, cooling, air conditioning, fuel burning or refrigeration work files a $25,000 bond with DLI ($100 biennial filing fee); the bond is 'in lieu of all other bonds to any political subdivision' but does not replace city licenses, and DLI tells contractors they 'must comply with local licensing requirements'. Whether an individual must hold a master-level card depends on the city.
Minneapolis. Contractor licenses (HVAC Class A for installing, repairing or cleaning HVAC systems, HVAC Class B for cleaning only, Refrigeration Systems Installer, Gas Fitter) are issued by Business Licenses and Consumer Services and require the State of Minnesota $25,000 bond; the responsible person holds a Master Certificate of Competency under Minneapolis Code Chapter 278. Master Warm Air Ventilation and Master Refrigeration cards require four years (1,600 hours per year) of on-the-job experience and four years (576 hours) of trade-related education, eligibility approval by the Building Official (no fee), the ICC exam at Pearson VUE (80 questions, 75% to pass, $115; the refrigeration master exam is open book with a 3-hour limit) and a $30 card fee per trade. A Saint Paul card is accepted by reciprocity for $30 per trade. The city's contractor license fee is published on a fee page that could not be opened during verification.
Saint Paul. A Warm Air or Ventilation Business Trade License ($188 per year, expiring December 1) requires a current Saint Paul Master Warm Air and/or Ventilation Certificate of Competency or a current Minneapolis master card, the $25,000 DLI mechanical bond, a $500,000 certificate of insurance naming the city and workers' compensation proof; Refrigeration, Gas Burner, Oil Burner and Steam Fitting licenses follow the same pattern. Master competency exams for Warm Air/Ventilation are given in January and July; reciprocal master cards are issued on a current Minneapolis card for $24 per trade.
Rochester. An HVAC Contractor license ($125 per year) requires a full-time licensed HVAC Master Installer; the Master Installer license ($60 per year) is issued to the individual after a City of Rochester certificate of competency ($25 per area of competency).
Bloomington. Mechanical contractor licenses (HVAC, gas installer, hot water/steam, oil burner, refrigeration) require a Minneapolis or Saint Paul Certificate of Competency or passing Bloomington's $35 open-book mechanical test on the 2020 Minnesota Mechanical and Fuel Gas Code, plus the DLI bond and a Minnesota tax ID.
Duluth. No city mechanical license; permits are issued to DLI-bonded mechanical contractors.
Out-of-state holders. No Minnesota city reviewed here publishes reciprocity or endorsement for another state's master HVAC or mechanical contractor license. A master arriving from another state can contract statewide by filing the DLI bond, and in Minneapolis, Saint Paul or Rochester must additionally document four years of experience and education and pass that city's master exam (a Minneapolis card then reciprocates to Saint Paul and is accepted in Bloomington).
