Pennsylvania to Texas: master HVAC technician license reciprocity

No credit· Start overVerified September 15, 2026· 12 sources

Pennsylvania does not issue a statewide master HVAC technician license, so there is nothing to transfer. Here is Texas'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 or municipal contractor license without a reciprocity agreement

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

A contractor licensed in a state other than Georgia or South Carolina (or by a municipality) files the standard Air Conditioning and Refrigeration Contractor License Application with the $115 fee, a copy of the current license, a list of the requirements met to obtain it and proof of its issue date and duration. TDLR reviews whether those requirements were substantially equivalent to Texas's and counts qualifying experience toward the 48-month requirement, but its out-of-state page warns that 'depending on the requirements of your current license, you may be required to complete some or all of the Texas requirements for licensure, including taking a licensing examination.' Applicants should therefore expect to take the PSI exam for the class and endorsement they want, and must file proof of Texas-compliant liability insurance after passing before the license issues.

TDLR does not publish which states it has found substantially equivalent or the criteria for waiving the exam; the FAQ says only that experience from states or municipalities with substantially equivalent requirements is accepted. Texas has no separate business or law exam for ACR contractors.

How Texas licenses master HVAC technicians

Texas master HVAC technician · “Air Conditioning and Refrigeration Contractor (Class A or Class B)”

Statewide license

Verified September 15, 2026· 8 sources

Issued by Texas Department of Licensing and Regulation (TDLR)

Texas's highest HVAC credential is the Air Conditioning and Refrigeration Contractor license issued to an individual by TDLR, so it is mapped here to the master level. The license comes in Class A (units of any size) and Class B (cooling up to 25 tons and heating up to 1.5 million Btu/h) with Environmental Air Conditioning, Commercial Refrigeration and Process Cooling or Heating endorsements. A new applicant must be 18, document 48 months of practical ACR experience under a licensed contractor in the past 72 months (or 12 months as a certified technician plus 36 months of experience, with substitutions for HVAC/R degrees, engineering licenses and military training), pay a $115 application fee, pass the PSI exam for each class and endorsement ($74 Class A, $60 Class B, 70% to pass) within one year of filing, and file proof of commercial general liability insurance ($300,000 per occurrence/$600,000 aggregate for Class A; $100,000/$200,000 for Class B). The license is valid one year, renews for $65 and requires 8 hours of continuing education a year; a company must employ a licensed contractor at each permanent location. TDLR has reciprocity agreements with Georgia and South Carolina only; licensees from every other state or municipality apply under TDLR's substantial-equivalence review and may be required to take the Texas exam.

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.
