Pennsylvania to South Carolina: master HVAC technician license reciprocity

No credit· Start overVerified September 15, 2026· 7 sources

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

Licensure by examination with credit for out-of-state experience (states without a waiver agreement)

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

A contractor from a state (or classification) not on the Board's waiver list is told plainly: 'you are not eligible for waiver/reciprocity. You will be required to take the SC exams.' The applicant passes the South Carolina technical exam for each classification wanted (Air Conditioning, Heating, Refrigeration or Packaged Equipment) through PSI and the South Carolina Business Management & Law for Commercial Contractors exam, then files the Qualifying Party application (Doc. 168) with proof of at least 2 years of full-time work experience performed within the past 5 years in each classification, which may have been earned in any state and should primarily reflect commercial work (a PHCC Academy of North Carolina heating and air-conditioning apprenticeship certificate is an alternative). The business files the Mechanical Contractor license application with the $350 licensure fee and a financial statement (or surety bond) meeting the group limit it wants. Section 40-11-290 separately allows the Board to exempt the technical exam for an applicant who verifies passing an essentially identical exam in another state even without a reciprocal agreement, but the Board's published waiver list and instructions do not describe a process for invoking it outside the listed states. A licensee who only wants residential work can instead apply to the Residential Builders Commission for the Residential HVAC Installer and Repairer license (one year of residential HVAC experience within the past five, residential technical exam at 65% and Business Management and Law exam, $135 application and $220 license fees, $10,000 bond for work over $5,000).

PSI exam fees are paid directly to PSI and are not published on LLR's pages. The Board's licensure page shows a $350 licensure fee but no separate qualifying-party application fee. Whether the NASCLA accredited examinations are accepted for the HVAC classifications is not stated on the pages opened (Doc. 168 mentions NASCLA transcripts generally). The current Mechanical Group financial thresholds on the licensure page (Group 2: $100,000 per job, $10,000 working capital or $15,000 net worth, $15,000 bond) differ from the 2019 waiver document's table; the web page is treated as current. EPA Section 608 certification is not mentioned on the Board's pages but is required by federal law.

Statewide license

Verified September 15, 2026· 6 sources

Issued by South Carolina Contractor's Licensing Board (LLR); Residential Builders Commission for residential-only work

South Carolina has no 'master HVAC' license. The highest person-held HVAC credential is the Contractor's Licensing Board's Qualifying Party certification in the Air Conditioning (AC), Heating (HT), Refrigeration (RG) or Packaged Equipment (PK, up to 25 tons and 500,000 BTU per unit) classification of the Mechanical Contractor license: the individual passes the South Carolina technical exam for each classification through PSI and the South Carolina Business Management & Law for Commercial Contractors exam, documents two years of experience within the past five (or a PHCC Academy of North Carolina heating and air-conditioning apprenticeship), and is certified as the qualifying party for a licensed entity (which may be a sole proprietorship); the certification stays with the person, who 'is not a licensed contractor' alone. The license itself is issued to the business, with a $350 licensure fee and a financial statement or surety bond sized by license group (Mechanical Group 2, jobs to $100,000: working capital $10,000 or net worth $15,000, or a $15,000 bond). A residential-only alternative is the Residential Builders Commission's Residential HVAC Installer and Repairer license ($135 application, $220 license), issued to the individual after one year of residential HVAC experience and the residential technical plus Business Management and Law exams. South Carolina has technical-exam waiver agreements, listed in the Board's Reciprocity/Waiver Agreements document, covering HVAC classifications for Georgia (Un-Restricted Conditioned Air), Louisiana (Statewide Mechanical), Ohio (HVAC, packaged equipment only), Tennessee (CMC and CMC-C), Texas (Class A and Class B ACR) and Utah (S350, S353, S351, S360), plus the MASC/CAGC HARV Master Mechanical card; Alabama, Mississippi and North Carolina licenses waive only the residential license's technical exam. Every waiver applicant must still pass the South Carolina Business Management & Law exam. Licensees from other states take the South Carolina technical exam. EPA Section 608 certification is a separate federal requirement.

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.
