Wyoming to Oklahoma: journeyman HVAC technician license reciprocity

No credit· Start overVerified September 15, 2026· 8 sources

Wyoming 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; vendor claims of HVAC reciprocity with Texas, Arkansas, Kansas or New Mexico could not be confirmed from an official page (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

Verified September 15, 2026· 6 sources

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 Wyoming has nothing to transfer

Wyoming journeyman HVAC technician

Licensed by cities and counties

Verified September 15, 2026· 12 sources

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.
