Nevada to Oklahoma: journeyman HVAC technician license reciprocity
Nevada 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; some third-party sites claim HVAC reciprocity with Texas, Arkansas, Kansas or New Mexico, but no CIB page lists such an agreement (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
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 Nevada has nothing to transfer
Nevada journeyman HVAC technician
Licensed by cities and counties
Nevada has no statewide journeyman or technician license for heating, air-conditioning or refrigeration work. The Nevada State Contractors Board (NSCB) licenses refrigeration and air-conditioning contractors under classification C-21 (NRS/NAC 624), issues licenses only to businesses with a qualifying individual, and its FAQ confirms it does not license individual journeymen, so an out-of-state HVAC journeyman license has nothing to transfer to at the state level and is not needed to work for a licensed C-21 contractor in most of the state. A personal credential exists only under local building codes in the Las Vegas valley: Clark County Code §22.02.250 and the City of Las Vegas Administrative Code §306 both require a mechanical qualified individual or a journeyman HVAC mechanic to be present in a supervisory capacity whenever permitted mechanical work of residential or light-frame construction is under way, and Clark County Code §22.02.260 defines the Journeyman HVAC Mechanic category. The credential is a county photo certificate earned by passing the journeyman HVAC exam accepted by the Building Official, historically ICC exam 459 (80 open-book questions on the Uniform Mechanical Code, 4 hours, $100) followed by a $10 ID card valid three years and renewed for $30 with 15 hours of UMC continuing education. Neither jurisdiction publishes a waiver or equivalency for an out-of-state license; Clark County's only equivalency is for a certificate from its accepted testing agency or another Nevada political subdivision within the county. Reno requires journeyman cards for electrical and plumbing work only, and the rural counties were not surveyed. EPA Section 608 certification applies federally to anyone handling refrigerants.
How local licensing works in Nevada
How local licensing works. NRS Chapter 624 licenses only contractors. A C-21 Refrigeration and Air-Conditioning license (NAC 624.380, with subclassifications C-21a Refrigeration through C-21g Industrial Piping) is issued to a business and qualified by an individual with four years of journeyman-or-higher experience; the NSCB's own FAQ says it does not license individual journeymen. Whether a working HVAC mechanic needs a personal card is decided by each county's or city's building administrative code, and only the southern Nevada jurisdictions were found to require one.
Clark County (unincorporated Las Vegas valley, Laughlin and other unincorporated areas). Clark County Code §22.02.245 issues mechanical permits only to contractors holding an active Nevada C-21 license. §22.02.250(B) requires the contractor to employ at least one mechanical qualified individual and, as amended in 2010 by Ordinance 3899, to have a mechanical qualified individual or a journeyman HVAC mechanic present during work hours in a supervisory capacity on every job site where permitted mechanical work of residential or light-frame construction is being performed. §22.02.255 defines a journeyman as someone who has passed the appropriate journeyman examination accepted by the Building Official and makes certificates renewable; §22.02.260(A)(9) lists 'Journeyman HVAC Mechanic - all aspects of mechanical work; mechanical work of residential and light frame construction' and requires certificates to be kept current with the county's accepted third-party testing agency. The only equivalency in the code (§22.02.255(C)) is for a current certificate from an accepted independent testing agency or from a Nevada political subdivision inside Clark County; there is no provision for other states' licenses, and unlike plumbing no experience prerequisite is stated for the HVAC exam. Under the county's ICC bulletin (June 30, 2014) the exam is ICC 459 Nevada (Clark County) Journeyman HVAC Mechanic: 80 multiple-choice questions, open book, 4 hours, $100, scheduled through Pearson VUE; the ID card costs $10, is valid three years, and is renewed for $30 with 1.5 CEUs (15 hours) on the current Uniform Mechanical Code and local amendments from approved providers (CSN, IAPMO, ICC, SMWIA, NATE, OSHA, RSES, SMACNA); a card expired more than one year requires re-examination.
City of Las Vegas. The City of Las Vegas Administrative Code (2019 edition) §306 carries the same rule: at least one mechanical qualified individual on staff, and a mechanical qualified individual or journeyman HVAC mechanic on site in a supervisory capacity for permitted residential or light-frame mechanical work, with certifications issued or approved by the city. The county's pages do not say who now proctors the journeyman HVAC mechanic exam and issues the card; applicants should confirm with the Clark County Department of Building and Fire Prevention before scheduling.
Out-of-state holders. No jurisdiction publishes a reciprocity or endorsement path for an out-of-state HVAC journeyman or technician license. The practical route is to pass the Clark County journeyman HVAC exam once and obtain the county card, which is honored in the City of Las Vegas; EPA Section 608 certification is required separately under federal law.
