Pennsylvania to Massachusetts: master HVAC technician license reciprocity

No credit· Start overVerified September 15, 2026· 11 sources

Pennsylvania does not issue a statewide master HVAC technician license, so there is nothing to transfer. Here is Massachusetts'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.

Refrigeration Contractor by examination with out-of-state license credit (all states)

Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.

A master HVAC technician or HVAC/refrigeration contractor licensed in any other state applies to OPSI for the Refrigeration Contractor examination online through the My License portal or by mail. The Massachusetts prerequisites are 2,000 hours held and used under a Massachusetts Refrigeration Technician license plus 100 hours of post-apprenticeship refrigeration training at an approved school; the application form lets the applicant instead certify 'I held and used a refrigeration license in another jurisdiction for not less than 2000 hours' and that the 100 hours of additional training were taken at an institution in another jurisdiction, with employer and school documentation, and states that such an application may be forwarded to the Bureau, which may allow the candidate to sit for the examination. Under 528 CMR 11.07(1) the Bureau decides whether the out-of-state license and its underlying experience and education are substantially equivalent and may grant partial credit or deny the petition. The applicant also submits proof of age (18+) and a 2x2 photo with the $150 non-refundable fee, is notified about four to eight weeks after receipt, and must pass the contractor exam at 70% (a failing candidate reapplies). The exam is not waived for any state because the Bureau has no reciprocity agreement; the license renews for $75.

528 CMR 11.03 states the master prerequisite as 2,000 hours 'as a Massachusetts Journeyman Refrigeration Technician', while the Bureau's own contractor application accepts 2,000 hours under a refrigeration license from another jurisdiction if the Bureau agrees; the form governs in practice but the outcome is at the Bureau's discretion. Whether the Bureau would instead require the applicant to obtain the Massachusetts Refrigeration Technician license first was not confirmed from an official page. No separate business or law examination is published for this license. The contractor how-to page and form list only the $150 application fee; any exam fee or initial license fee after passing was not confirmed. The 42-day timeline reflects the published four-to-eight-week notification window.

How Massachusetts licenses master HVAC technicians

Massachusetts master HVAC technician · “Refrigeration Contractor (Master Refrigeration Technician)”

Statewide license

Verified September 15, 2026· 9 sources

Issued by Bureau of Pipefitters, Refrigeration Technicians and Sprinkler Fitters (Massachusetts Office of Public Safety and Inspections, Division of Occupational Licensure)

Massachusetts' highest personal HVAC-type credential is the Refrigeration Contractor license, which M.G.L. c. 146, § 81 calls the 'master refrigeration technician' and 528 CMR 11.03 the 'Master Refrigeration Technician/Contractor'. It is issued by the Bureau of Pipefitters, Refrigeration Technicians and Sprinkler Fitters (OPSI) to an individual who has held and used a Massachusetts Refrigeration Technician license for at least 2,000 hours and completed 100 hours of additional Bureau-approved refrigeration training; it allows the holder to establish a refrigeration business and employ licensed technicians and apprentices, and the license number must appear on vehicles and invoices. The applicant pays a $150 non-refundable application fee and must pass the OPSI contractor exam at 70%; the license renews for $75. There is no general HVAC or mechanical contractor license in Massachusetts; hydronic heating contractors hold a Master Pipefitter license and oil-burner firms are certified by the Department of Fire Services. The contractor application lets an out-of-state applicant substitute 2,000 hours under a refrigeration license held in another jurisdiction and 100 hours of training taken elsewhere, subject to the Bureau agreeing to let the candidate sit the exam; the exam itself is never waived because the Bureau has no reciprocity agreements.

Why Pennsylvania has nothing to transfer

Pennsylvania master HVAC technician

Licensed by cities and counties

Verified September 15, 2026· 18 sources

Pennsylvania issues no statewide master HVAC, mechanical or HVAC contractor license; none of the Department of State's licensing boards covers the trade, and the Attorney General's Home Improvement Contractor registration (required of businesses doing residential remodeling work, including HVAC replacement in existing homes) is a no-exam consumer-protection registration rather than a license. The master-level credential exists only in cities that have chosen to license the trade, under names that vary: Pittsburgh's Mechanical/HVAC Trade License (issued to an individual with four years of experience who has passed an ICC National Standard Master Mechanical exam; $120 in 2025, eight CE hours a year), Reading's Master Mechanical Heating Contractor license (two years as a licensed journeyman plus the ICC F29-N Master Mechanical exam; $90), Erie's master Mechanical and HVAC Installer licenses, and Scranton's Master Mechanical Contractor license. Philadelphia and Altoona require only a general contractor license (business-level, insurance and no exam) to pull mechanical permits, and Allentown and Harrisburg publish no HVAC license at all. There is no state-level recognition of an out-of-state master HVAC license, but Pittsburgh accepts any passed ICC master mechanical exam from any code year and, on the License Officer's review, equivalent exams from other states, and Reading issues a reciprocal master license ($190) to holders of an equivalent license from a first-, second- or third-class city or from a state with a state license and equal standards. A master from another state should expect to document experience, present an ICC master mechanical exam score, and apply separately in each city where they will pull permits.

How local licensing works in Pennsylvania

How local licensing works. With no state HVAC board, each Pennsylvania city that licenses the trade does so under its own ordinance. The credential that travels best between them is the ICC National Standard Master Mechanical examination, which Pittsburgh and Reading both use and which Reading's reciprocity practice implicitly relies on.

Philadelphia. No HVAC or mechanical trade license. Mechanical permits must be performed by a business holding the general Contractor License: $126 a year (including a $20 application fee), general liability of $500,000 per occurrence, $300,000 auto liability, workers' compensation, a Commercial Activity License and tax ID, tax compliance, and an OSHA 30 course for supervisors; there is no exam or experience requirement and no out-of-state provision. Ductwork on the job must be done by licensed sheet metal technicians or apprentices employed by the contractor. Businesses working only on existing one- or two-family homes may register as home improvement contractors instead.

Pittsburgh. The Department of Permits, Licenses and Inspections issues the Mechanical/HVAC Trade License to individuals ('Trade Licenses are issued to individuals, not to companies'), required to install, erect, enlarge, repair, alter, remove, convert or replace any mechanical system in the city (Pittsburgh Code 741). New applicants provide proof of passing the City-proctored Master Mechanical exam or an ICC Standard Master Mechanical exam for any code year, and a resume or employer statement showing four or more years of practical experience (notarized statement if self-employed). PLI's rules state that 'equivalent certification testing programs from states other than Pennsylvania shall be accepted as proof of compliance of the testing requirements upon review and determination of equivalence by the License Officer'. The 2025 fee is $120 (initial and renewal); licenses expire 365 days after issue and renewal requires eight hours of continuing education in the prior twelve months. Insurance ($1,000,000 per occurrence / $2,000,000 aggregate general liability plus workers' compensation) is not needed at application but must be on file before any permit is issued. Applications go through OneStopPGH.

Reading. The Master Mechanical Heating Contractor license ($90 a year) requires a valid mechanical journeyman license, at least two years employed as a mechanical journeyman by a registered mechanical contractor, and a passing ICC F29-N Master Mechanical exam (or its successor). A reciprocal master license ($190, including a one-time reciprocation fee and the annual 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 of examiners with standards equal to Reading's; the applicant attaches the other jurisdiction's current requirements. As of 7/7/2023 Reading lists reciprocity with Harrisburg, Philadelphia, Scranton, Lancaster and Pittsburgh and with 'most, if not all, surrounding states with a state license'.

Erie. Master licenses are required for Mechanical and HVAC Installers, with a separate Refrigeration license, and 'Only Master License holders are able to obtain a permit'; applications are reviewed by the Trades Licensing Board, which also handles temporary licenses. The ordinance defines the Master Mechanical Contractor as one who contracts to install, erect, alter, extend, maintain or repair heating and ventilation, air-conditioning and refrigeration systems, process piping and sheet metal work. Fees, insurance and any reciprocity provisions could not be opened.

Scranton. Issues a Master Mechanical Contractor license through a combined master electrical/mechanical/plumbing/general contractor application; the application's terms could not be opened. Reading treats Scranton as a reciprocal city.

Altoona. HVAC contractors need a city business license, and for commercial work a City of Altoona Contractor's License with liability and workers' compensation insurance; residential work requires only the state Home Improvement Contractor registration.

Allentown and Harrisburg. Neither publishes an HVAC or mechanical license (Allentown licenses electricians, plumbers and sheet metal workers; Harrisburg licenses electricians, plumbers and low-voltage installers).

Out-of-state holders. Pittsburgh's acceptance of any ICC master mechanical exam (and, on review, equivalent out-of-state exams) and Reading's reciprocal license are the only published accommodations; neither waives the experience documentation or local fees. Everywhere else the out-of-state license is irrelevant and the contractor obtains the local business-level license.
