Louisiana to North Carolina: master HVAC technician license reciprocity

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

Louisiana does not issue a statewide master HVAC technician license, so there is nothing to transfer. Here is North 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.

Out-of-state master HVAC or HVAC contractor without a waiver (all other states)

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

The Board's 2026 application packet states that there is no license reciprocity, that all applicants must meet the North Carolina experience requirements, and that 'there are currently no other waivers available for any other states or any other licenses' beyond South Carolina. G.S. 87-21(g) lets the Board license contractors from other states without written examination after 'a complete and exhaustive review' finding the other state's requirements substantially equivalent, but the Board has exercised that authority only for South Carolina. A master HVAC technician or HVAC contractor from any other state therefore applies to sit the examination: 4,000 hours of hands-on experience in the heating group sought (up to half from college or technical-institute coursework), which may have been earned anywhere and is documented on the Applicant Employment History form (1-C) with W-2s or 1099s when it was not earned under a North Carolina licensee. The $150 exam fee, a Disahealthcare criminal background report and Form SSA-89 are submitted with the application; after approval (4-6 weeks) the candidate schedules the 4-hour technical exam and 1.5-hour Business and Law exam with PSI. An applicant who passes the technical portion but fails the business portion may take a Heating Technician license instead. A North Carolina resident licensed in Georgia, Tennessee, Virginia or West Virginia may instead use the Neighbor State License Recognition Act (see agreements).

Separate application and fee for each heating classification. An H3-I licensee gets 50% experience credit toward H2 and vice versa. The $150 annual license fee is the figure printed in the Board's application packet for licensure without examination; the Board's fee page could not be opened to confirm the schedule for first-time licensees.

How North Carolina licenses master HVAC technicians

North Carolina master HVAC technician · “Heating Contractor (H1-I / H1-II, H2, H3-I / H3-II)”

Statewide license

Verified September 15, 2026· 11 sources

Issued by North Carolina State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors

North Carolina has no 'master HVAC' license; its highest HVAC credential is the Heating Contractor license issued to an individual by the State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors under G.S. 87-21, in Heating Group 1 (steam, vapor and hot-water comfort heating), Group 2 (forced-air heating/cooling with more than 15 tons of cooling) and Group 3 (forced-air heating/cooling of 15 tons or less), each with Class I (any building) and Class II (single-family detached dwellings) except Group 2, which is Class I only. The license is earned personally by passing the 4-hour technical exam and the 1.5-hour Business and Law exam and belongs to the individual, who may list it in a firm name and add sub-licensees; that is why this site maps it to the master level. A new applicant needs 4,000 hours of hands-on experience (up to half from technical education), pays $150 per examination, submits a nationwide criminal background report and Social Security verification, and after licensure pays an annual license fee of $150. The Board states that it has no license reciprocity with any state; the only technical-exam waiver is with South Carolina, and North Carolina residents licensed in Georgia, South Carolina, Tennessee, Virginia or West Virginia may ask for licensure without examination under the Neighbor State License Recognition Act. Commercial, industrial, transport and service refrigeration (not comfort cooling) requires a separate Class I-IV Refrigeration Contractor license from the State Board of Refrigeration Contractors ($100 exam, 4,000 hours, EPA 608 Type II or Universal required), which has no reciprocity but offers the same neighbor-state route to new NC residents. EPA Section 608 certification is required federally to handle refrigerants.

Why Louisiana has nothing to transfer

Louisiana master HVAC technician

Licensed by cities and counties

Verified September 15, 2026· 16 sources

Issued by Parish and municipal building departments (no state master license); Louisiana State Licensing Board for Contractors licenses mechanical contractors only

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.
