Louisiana to South Carolina: master HVAC technician license reciprocity
South Carolina has a reciprocity agreement with Louisiana: a Louisiana master HVAC technician can get a South Carolina license without retaking the trade exam.
Reference only, not legal advice. Rules change; confirm with the licensing board before you apply. Full disclaimer.
Technical-exam waiver for Louisiana Statewide Mechanical licensees (AC and HT)
A signed state-to-state agreement. The trade exam is waived; you apply, prove your history, and pay the fee.
The Board's Reciprocity/Waiver Agreements list accepts the Louisiana 'Statewide Mechanical' exam for the South Carolina Air Conditioning (AC) and Heating (HT) classifications. A Louisiana mechanical contractor who passed that exam and holds a current license in good standing (not grandfathered or waived in) has the South Carolina technical exams waived but must still pass the South Carolina Business Management & Law for Commercial Contractors exam through PSI, have the Louisiana State Licensing Board for Contractors complete the SC Examination Waiver form, document 2 years of experience within the past 5, and file the Qualifying Party application; the business then pays the $350 licensure fee and files its financial statement or bond. South Carolina's agreements 'ONLY WAIVE THE TECHNICAL PORTION OF THE EXAM.'

How South Carolina licenses master HVAC technicians
South Carolina master HVAC technician · “Mechanical Contractor, Air Conditioning (AC) / Heating (HT) / Refrigeration (RG) classification - Qualifying Party certification”
Statewide license
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 Louisiana has nothing to transfer
Louisiana master HVAC technician
Licensed by cities and counties
Louisiana does not issue a statewide master HVAC or master mechanic license. The state-level credential for HVAC work is the Louisiana State Licensing Board for Contractors (LSLBC) commercial license in the Mechanical classification (major classification 6, or subclassification 6.1 Heat, Air Conditioning, Ventilation, Duct Work and Refrigeration), mandatory for any mechanical project of $10,000 or more; it is a contractor license issued to the business (or a sole proprietor) and qualified by a natural person, the qualifying party, who passed the trade exam through PSI, so it is treated here as a business license rather than a person-held master credential. Master mechanic licenses exist only at the local level: New Orleans issues a Class 'A' Master Mechanical Contractor License ($110 per year) to an applicant who passed the ICC G29 Master Mechanical exam directly or through LSLBC state testing, carries $500,000 of general liability insurance, and is the only Class 'A' holder for the company; Jefferson Parish issues a $200 parish trade contractor license built on the state license. For the state contractor license the LSLBC waives the trade exam for any applicant who passed a comparable classification exam in any other state without waivers, exemptions or grandfathering, with no partner-state list since October 23, 2024, but the Business and Law course/exam, the financial statement and the other licensing requirements are never waived. No parish or city page reviewed publishes reciprocity for out-of-state master licenses. Federal EPA Section 608 certification applies to anyone who handles refrigerants.
How local licensing works in Louisiana
State contractor license (not a master license). Under La. R.S. 37:2150.1(16) a mechanical contractor is anyone contracting for air conditioning, refrigeration, heating, plumbing, ventilation, boiler or piping work of $10,000 or more, and the LSLBC issues the commercial license to that person or business with a Mechanical classification (or the 6.1 Heat, Air Conditioning, Ventilation, Duct Work and Refrigeration subclassification) qualified by a designated qualifying party. Applicants file the online application with a financial statement (required of all applicants), Secretary of State registration for any business entity including out-of-state companies, the online Business and Law course/exam, and the PSI trade exam for the classification (PSI has administered all LSLBC trade exams since August 5, 2025); statutory fee caps are $50 per examination, $100 license and $100 renewal, plus a surcharge of up to $400 that the board may assess on a contractor not domiciled in Louisiana. Reciprocity for the state license: R.S. 37:2153(F)(5) directs the board to waive the trade portion of the exam for an applicant licensed in a comparable classification in another state on written certification that the applicant passed that classification's exam and is in good standing, and the Executive Director's October 23, 2024 letter extends this to any state: a classification exam passed in any other state 'with no waivers, exemptions, or grandfathering in effect' is accepted for the equivalent Louisiana classification, and all previous state-to-state agreements were declared null and void. The applicant has the origin board complete the Reciprocity Request form (license status, disciplinary history, and the name, exam developer, date and score of each person who passed the trade exam) and uploads it with the application; the exam/administrative fee is still charged, and the business law requirement 'shall not be waived'. Once licensed, R.S. 37:2156.1(I) exempts the contractor and its employees from any parish or city examination or certification.
New Orleans. The Class 'A' Master Mechanical Contractor License covers air conditioning and refrigeration (and, separately, gasfitters): the applicant submits a passing ICC Official Results Report for exam G29 Master Mechanical, obtained from ICC directly or through state testing with the LSLBC, plus certificates of general liability insurance of at least $500,000 and workers' compensation naming the City as certificate holder, a photo and ID; the license costs $110 per year active or $25 inactive, with a $10 per month delinquent fee, renews from 90 days before the holder's birthday, and only one Class 'A' holder is allowed per company. The city page states no experience requirement and no reciprocity.
Jefferson Parish. A parish trade contractor license ($200 new) is issued to a license holder/qualifying party for mechanical work and lists the state license, occupational license, sales tax registration, liability insurance and workers' compensation on its checklist; air conditioning and heating equipment may be installed or replaced only under a filing by a parish-licensed mechanical contractor.
Shreveport. Requires city contractor registration for anyone performing HVAC work and the state license for work over $10,000; master testing is referred to the ICC or the LSLBC.
Baton Rouge and Lafayette. No official page describing a master mechanic license was located for East Baton Rouge Parish or Lafayette Consolidated Government.
Out-of-state holders. A master HVAC contractor from another state who wants to contract in Louisiana applies for the LSLBC commercial license with the Mechanical classification and, if the origin license was earned by a trade exam, requests the trade-exam waiver by reciprocity; the Business and Law course and financial statement are still required. City licenses such as New Orleans Class 'A' can then be obtained on the ICC G29 exam or LSLBC testing.
