Wyoming to Connecticut: journeyman HVAC technician license reciprocity
Wyoming 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 Wyoming has nothing to transfer
Wyoming journeyman HVAC technician
Licensed by cities and counties
Wyoming has no statewide HVAC, refrigeration or mechanical license at any level; the only state trade-licensing program is the Department of Fire Prevention and Electrical Safety's electrician program, whose closest credential is the LM-H Limited Technician license for the electrical wiring of HVAC systems. Licensing of HVAC journeymen exists only where a city ordinance creates it. Cheyenne, Casper, Laramie and Gillette each license HVAC/mechanical journeymen (and apprentices) individually, all built on the ICC National Standard mechanical exams (Casper names G31-N/G29-N) and four years of documented apprentice-level experience, while Rock Springs only registers contractors with proof of insurance and licenses no individuals. None of these cities publishes reciprocity with other states' HVAC licenses: Casper's and Gillette's reciprocity provisions apply only to other Wyoming jurisdictions, Cheyenne's Board may grant reciprocity 'as the Board determines appropriate' and treats even in-state licenses case by case, and Laramie's building official may issue a certificate without examination to the holder of a certificate from any other governmental agency whose exam is judged at least equal. In practice an out-of-state journeyman brings their ICC mechanical exam certificate (or takes it through Pearson VUE) and applies in each city where they will work. EPA Section 608 certification is federal and required everywhere refrigerants are handled; Cheyenne and Gillette require it expressly for refrigeration licenses.
How local licensing works in Wyoming
How local licensing works. Wyoming licenses electricians at the state level but not HVAC, refrigeration, sheet metal or plumbing workers, so HVAC licensing is entirely a matter of city ordinance and varies by city. The state's reciprocity statute cited by the cities covers only licenses from other Wyoming jurisdictions.
Cheyenne. The Contractor Licensing Board licenses HVAC and refrigeration contractors (Class C1, tested) and requires every employee on an HVAC or refrigeration job site to hold a master, journeyman or apprentice license. A journeyman must document 4 years/8,000 hours as a licensed apprentice (or certified equivalent training) with third-party verification and pass a current ICC, NICET or NASCLA exam from the Board's list (paid to the testing agency); a residential plumbing/mechanical journeyman needs 2 years/4,000 hours. Fees: $50 application plus $30 initial, $15 renewal; apprentices $25 + $25. Refrigeration applicants must submit EPA Type II, III or Universal certification. A 30-day temporary work authorization is available to trade employees registered for the exam. Reciprocity (3.3.2): the Board may grant reciprocity with other jurisdictions as it determines appropriate and may accept a test exceeding the published exams from someone holding a current equivalent license elsewhere, but no partner list is published.
Casper. The Community Development Department issues Mechanical Journeyman licenses ($25 new, $15 renewal) to applicants who show completion of a federally recognized mechanical apprenticeship or the equivalent of four years in a Casper-licensed mechanical shop and proof of passing ICC G31-N, G29-N or equivalent; applications with notarized experience affidavits and exam proof go to the Chief Building Official, and the fee and insurance follow approval. Reciprocal licenses ($50/$25) exist only for holders of a current license from another Wyoming jurisdiction with comparable testing.
Laramie. Code Administration issues journeyman, master and apprentice certificates of qualification in mechanical, refrigeration and gas service; a mechanical journeyman needs 4 years as an apprentice (refrigeration and gas service 3) and passes the building official's exam (ICC-based, 2024 cycle; $5 application fee per exam). In lieu of the exam the building official may issue a certificate to anyone presenting a valid certificate from any other governmental agency whose exam the board of examiners considers at least equal, which is the only city provision that can reach an out-of-state license. Applications are filed through the Civic Access portal.
Gillette. Class D HVAC contractors must employ a Master of Record, and all master, journeyman and apprentice HVAC technicians are licensed individually by the Building Inspection Division. A Journeyman HVAC Mechanical license requires four years of approved experience and passing ICC exam results ($25 annual); apprentices need thirty days with a Gillette-licensed HVAC contractor ($5). Journeyman refrigeration technicians additionally need ESCO/EPA 608 certification. Since July 1, 2024 the Board of Examiners grants fee-free reciprocity only to active licenses from other Wyoming local governments; proof of the ICC mechanical exam satisfies all testing.
Rock Springs. Contractors register with the Building Inspection Office ($125, certificate of insurance); no individual HVAC licenses or exams exist.
Out-of-state holders. No Wyoming city publishes a reciprocity or endorsement path for another state's HVAC journeyman license. The portable credential is the ICC National Standard mechanical exam (Journeyman G31-N or Master G29-N), which Cheyenne, Casper, Laramie and Gillette all accept; an out-of-state journeyman who already holds an ICC certificate can generally apply directly, and one who tested on a state-specific exam should expect to take the ICC exam or, in Laramie, ask the board of examiners to treat the origin exam as equal.
