Wyoming to Rhode Island: journeyman HVAC technician license reciprocity

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.
