Minnesota to Connecticut: journeyman HVAC technician license reciprocity
Minnesota does not issue a statewide journeyman HVAC technician license, so there is nothing to transfer. Here is Connecticut'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.
Journeyperson by equivalent out-of-state license (all states)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
An HVAC technician licensed in any other state applies under DCP's 'Heating Journeyperson - Equivalent Out of State License' path. DCP reviews one out-of-state license for equivalency: it must have required the same number of classroom hours (576 for the S-2), an equivalent classroom curriculum matching DCP's Exhibit A courses, and the same on-the-job training hours (8,000 for the S-2) as the Connecticut license applied for; the limited D-2 class needs 4,000 OJT and 432 classroom hours and the B-2 needs 2,000 and 288. The applicant submits a copy of the license, an official license verification, the laws and regulations that set the requirements met to obtain it, and the scope of work for that license; only one license will be reviewed and the $90 application fee is non-refundable. If the license is found equivalent, DCP approves the applicant to sit the S-2 exam with PSI ($59 per portion, eligibility valid one year), and the license is issued after passing on payment of the $120 initial license fee. The out-of-state license does not waive the Connecticut exam because Connecticut has no reciprocal agreements. If the license cannot be shown equivalent, the applicant must instead document 576 classroom hours and 8,000 OJT hours with transcripts and notarized employer letters under the equivalent experience and training path.
DCP's out-of-state license page does not itself restate that the exam is required; the exam requirement follows from the Heating, Cooling and Sheet Metal Work Licenses page (every individual applicant must take an exam), CGS 20-334a(a)(2) (competency shown by the state licensure examination) and the PSI bulletin (the State determines eligibility, then the candidate tests). CGS 20-333a permits licensure without examination only where the other state reciprocates for Connecticut licensees, and DCP states no such agreements exist. Many states issue a single HVAC or refrigeration license rather than a heating-piping-cooling license with a 576-hour curriculum, so an applicant may be found equivalent only to a limited class such as the D-2. Neither DCP page mentions EPA Section 608; it is a federal requirement that applies regardless. Typical processing time is not published.

How Connecticut licenses journeyman HVAC technicians
Connecticut journeyman HVAC technician · “S-2 Unlimited Heating, Piping and Cooling Journeyperson”
Statewide license
Connecticut licenses HVAC work statewide through the Department of Consumer Protection (DCP) as 'heating, piping and cooling' work; the journeyman-level credential is the S-2 Unlimited Heating, Piping and Cooling Journeyperson, which covers all heating, piping and cooling work defined in CGS 20-330 while employed by a licensed contractor. Narrower journeyperson classes exist for technicians whose experience is limited to part of the trade, chiefly the D-2 Limited Warm Air, Air Conditioning and Refrigeration Journeyperson (no oil burner servicing) and the B-2 Limited Gas and Oil Burner Journeyperson, plus D-4 cooling-only, G-2 gas piping and S-10 light heating-cooling classes. A new S-2 applicant qualifies through a Connecticut apprenticeship, through equivalent experience and training (8,000 on-the-job hours and 576 classroom hours), or by holding an equivalent out-of-state license, and in every path must pass the PSI-administered S-2 exam (70 questions, 3 hours, 70%, open book). DCP states that Connecticut does not have reciprocal agreements with any other jurisdiction, even though CGS 20-333a would allow the Commissioner to waive the exam for licensees of states that reciprocate. The application fee is $90, the exam is $59 per portion and the initial license fee is $120; licenses expire every August 31 and renew for $120. EPA Section 608 refrigerant certification is a separate federal requirement for anyone handling refrigerants.
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).
