Pennsylvania to District of Columbia: journeyman HVAC technician license reciprocity

No credit· Start overVerified September 15, 2026· 9 sources

Pennsylvania 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

Verified September 15, 2026· 6 sources

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.

Pennsylvania journeyman HVAC technician

Licensed by cities and counties

Verified September 15, 2026· 16 sources

Pennsylvania has no statewide HVAC license at any level: none of the Department of State's 29 licensing boards covers heating, air-conditioning, refrigeration or mechanical work, and the only state-level credential touching the trade is the Attorney General's Home Improvement Contractor registration, which registers businesses doing residential work and involves no exam. Journeyman-level HVAC licensing exists only where a city ordinance creates it, and most cities do not: Philadelphia and Pittsburgh license no HVAC journeyman (Philadelphia's only person-held HVAC-related license is the Sheet Metal Technician license for ductwork, and Pittsburgh's Mechanical/HVAC Trade License is a master-level credential under which employees work unlicensed). Reading issues a Journeyman Mechanical Installer license based on a four-year apprenticeship and the ICC Journeyman Mechanical exam, and Erie's ordinance defines a mechanical journeyman by completion of the ICC Journeyman Certificate Exam. An out-of-state HVAC journeyman license has no state-level recognition in Pennsylvania; Reading will issue a reciprocal journeyman license ($150) to holders of an equivalent license from a first-, second- or third-class city with standards equal to its own, and otherwise the technician works as an employee of whatever contractor holds the local license. Federal EPA Section 608 certification is required everywhere in the state for anyone who handles refrigerants.

How local licensing works in Pennsylvania

How local licensing works. Pennsylvania licenses no HVAC workers at the state level, so each city decides for itself whether to license the trade, and licensing is done under local ordinances by city trade boards or code offices. Most municipalities require only a permit pulled by a contractor plus the statewide Home Improvement Contractor registration for residential work.

Philadelphia. No HVAC or mechanical license of any kind. Mechanical permits must be performed by a business holding L&I's general Contractor License ($126 a year, insurance and OSHA 30, no exam), and 'sheet metal work must be performed by a registered sheet metal technician or apprentice employed by the contractor'. The Sheet Metal Technician License ($189 for three years) is the only person-held HVAC-related credential; it requires a completed U.S. DOL or state-registered sheet metal apprenticeship (8,000 hours of work plus 800 hours of instruction) and has no exam and no out-of-state provisions.

Pittsburgh. No journeyman license. The Mechanical/HVAC Trade License is issued to an individual who passes an ICC master mechanical exam and shows four years of experience; other workers perform mechanical work as employees under a licensee.

Reading. Issues a Journeyman Mechanical Installer license ($50 a year). Applicants must be employed by a registered mechanical contractor and registered with the Pennsylvania apprenticeship bureau, complete a four-year approved apprenticeship with at least 216 hours of instruction per year (or eight years under a registered mechanical contractor), and pass the ICC F31-N Journeyman Mechanical exam or its successor. A reciprocal journeyman license ($150, including a one-time reciprocation fee) may be issued to the holder of an equivalent license from a first-, second- or third-class U.S. city issued by an equivalent board with standards equal to Reading's; the applicant attaches the other jurisdiction's current requirements. Reading's list names Harrisburg, Philadelphia, Scranton, Lancaster and Pittsburgh and 'most, if not all, surrounding states with a state license'.

Erie. The Bureau of Building Standards and Safety issues master licenses for Mechanical and HVAC Installers and a separate Refrigeration license, and the contractor licensing ordinance defines a journeyman as one qualified 'through formal apprenticeship, on-the-job experience and after successful completion of the International Code Council (ICC) Journeyman Certificate Exam', with apprentices completing 8,000 working hours and 800 classroom hours before testing. Fees, insurance and any reciprocity section of the ordinance could not be opened.

Allentown. Licenses electricians, plumbers and sheet metal workers only; no HVAC or mechanical license.

Harrisburg, Scranton and Altoona. Harrisburg posts electrical, plumbing and low-voltage license applications only. Scranton and Altoona license HVAC/mechanical contractors at the master or business level (see the master level) and have no journeyman license.

Out-of-state holders. No city publishes a reciprocity path for out-of-state journeyman licenses except Reading, whose reciprocal license depends on the origin credential coming from a city (or a state) with equivalent standards. Elsewhere a journeyman from another state simply works for a locally licensed contractor.
