Illinois to Oklahoma: journeyman HVAC technician license reciprocity
Illinois 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 Illinois has nothing to transfer

Licensed by cities and counties
Illinois has no statewide HVAC license at any level; the Illinois Department of Financial and Professional Regulation licenses no heating, air conditioning, refrigeration or mechanical trade, and licensing exists only where a city or county has adopted its own ordinance. None of the major jurisdictions verified for this entry issues a journeyman or technician HVAC card: Chicago licenses general contractors but no mechanical trade, Springfield's Mechanical License is a master-level credential (5 or 7 years of experience plus the ICC Master Mechanical exam), and Peoria, Aurora, Elgin and Cook County license or register the contractor. HVAC technicians therefore work as employees of a locally licensed or registered contractor without a personal license. An out-of-state journeyman HVAC license carries no recognition in Illinois, and none of the jurisdictions checked publishes a reciprocity or endorsement path for it; a journeyman who wants to pull permits must qualify for the local mechanical contractor license, which in most testing cities means passing the ICC Master Mechanical exam. Federal EPA Section 608 certification is required to handle refrigerants.
How local licensing works in Illinois
How local licensing works. There is no state HVAC license and no state mechanical board, so each municipality decides whether to license or register mechanical contractors, and the largest ones use the ICC National Standard Master Mechanical exam (G29/N29) as the test of competence. No verified jurisdiction licenses journeyman-level HVAC workers.
Chicago. The Department of Buildings licenses general contractors (Classes A-E, $300 to $3,500 a year with insurance from $1 million per occurrence) and specific trades such as supervising electricians, but has no HVAC or mechanical contractor or technician license; HVAC firms pull permits under a general contractor license and employees need no card.
Springfield. The Building and Zoning Department issues a Mechanical License to individuals (Residential: 5 years of experience and the ICC Master Mechanical G29 exam; Commercial: 7 years and the same exam) and separately registers mechanical contractors. There is no journeyman license; workers operate under the licensed individual.
Peoria. HVAC contractors are licensed or registered ($150 a year) on an ICC contractor test certificate from the 2018 code cycle or newer; holders of Normal or Pekin licenses register without retesting. No employee license.
Aurora and Elgin. Both accept the ICC Master Mechanical certification (Aurora N29, Elgin G29) or, in Elgin, a license from any Illinois city that gives a written exam; Aurora requires insurance naming the city and Elgin a $20,000 license and permit bond. The portable credential inside Illinois is the ICC Master Mechanical exam, which Springfield, Peoria, Aurora and Elgin all accept for the contractor-level license.
