Illinois to District of Columbia: journeyman HVAC technician license reciprocity
Illinois does not issue a statewide journeyman HVAC technician license, so there is nothing to transfer. Here is District of Columbia'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 journeyman HVAC technician (any state)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
The Board of Industrial Trades publishes no reciprocity for refrigeration and air conditioning mechanics, so a journeyman-level HVAC licensee from any state applies through the DLCP online portal as a new applicant. The application needs a passport-style photo, government ID, the $65 application fee, tax records and an employment verification letter signed by a master mechanic showing at least 3 years of experience, and a CFC Universal certification; the applicant then schedules the open-book journeyman exam with PSI (2012 International Mechanical Code and Modern Refrigeration and Air Conditioning) and pays the $110 license fee for a term ending September 30 of the next even-numbered year. Two statutory routes can waive the exam: D.C. Code § 47-2853.202(d) requires the Board to accept a certificate from a national certifying organization (a registered trade organization, non-union sponsor or labor union) that the applicant completed its apprenticeship, passed its exam and is designated a journeyman, and § 47-2853.12(b) directs boards to waive the exam for a licensee in good standing of a state whose standards were at least as high as the District's and which admits DC licensees in a like manner, with § 47-2853.08 leaving the substantial-equivalence finding to the Board case by case. No District-law exam applies; § 47-2853.12(c)(4) exempts journeyman refrigeration and air conditioning mechanics from one.
The Board's fee page refers exam fees to '§ 3500.3' without stating an amount; the PSI fee for the DC journeyman refrigeration exam could not be confirmed from an official page. Whether experience letters signed by an out-of-state master are accepted, and which states or national certifying organizations the Board has listed under § 47-2853.12(d), were not confirmed from an official page. The 3-year experience figure comes from DLCP's application instructions; the statute itself sets no journeyman experience term.

How District of Columbia licenses journeyman HVAC technicians
District of Columbia journeyman HVAC technician · “Journeyman Refrigeration and Air Conditioning Mechanic”
Statewide license
Issued by DC Board of Industrial Trades (Department of Licensing and Consumer Protection)
The District of Columbia licenses HVAC technicians as Refrigeration and Air Conditioning Mechanics through the Board of Industrial Trades in the Department of Licensing and Consumer Protection (DLCP), the same board that licenses electricians and plumbers. Three person-held credentials exist: apprentice (registered without exam), Journeyman Refrigeration and Air Conditioning Mechanic, and Master Refrigeration and Air Conditioning Mechanic (regular, or limited to systems of 25 compressor horsepower and below). 17 DCMR § 303.6 requires a journeyman license for anyone doing the mechanical work of installing, maintaining, repairing or replacing refrigeration and air conditioning equipment. DLCP's application instructions require 3 years of experience verified by a master, tax records, a CFC (EPA 608) Universal certification, and a PSI-administered open-book journeyman exam; a graduate of a registered apprenticeship program (classroom work plus 8,000 hours over 4 years under a master) may waive the journeyman exam, which mirrors the national-certification substitute in D.C. Code § 47-2853.202(d). Fees are a $65 application fee and a $110 mechanic license fee; all refrigeration licenses expire September 30 of even-numbered years. The Board publishes reciprocity for electricians and plumbers from Maryland and Virginia but none for refrigeration and air conditioning mechanics.
Why Illinois has nothing to transfer
Illinois journeyman HVAC technician
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. Neither licenses employees.
Unincorporated Cook County. HVAC contractors register as 'all other trades' ($150 initial, $75 annual, $1,000,000 liability insurance); no exam and no employee license.
Not verified. Naperville's contractor registration page could not be opened for this entry, and Rockford's site describes only electrical registration.
Out-of-state holders. No jurisdiction checked recognizes another state's journeyman HVAC license, because none issues one. The portable credential inside Illinois is the ICC Master Mechanical exam, which Springfield, Peoria, Aurora and Elgin all accept for the contractor-level license.
