Mississippi to South Carolina: master HVAC technician license reciprocity

Reciprocity· Exam waivedVerified September 15, 2026· 8 sources

South Carolina has a reciprocity agreement with Mississippi: a Mississippi 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 the Residential HVAC Installer and Repairer license only (no Mechanical Contractor waiver)

A signed state-to-state agreement. The trade exam is waived; you apply, prove your history, and pay the fee.

Mississippi appears on the Contractor's Licensing Board's waiver list only for its Building and Electrical exams, so a Mississippi HVAC contractor who wants the state Mechanical Contractor Air Conditioning, Heating or Refrigeration classification must pass the South Carolina technical exam(s) and the Business Management & Law exam like any other out-of-state applicant. The Residential Builders Commission, however, waives the technical portion of its Residential HVAC Installer and Repairer exam for 'a current license in the eligible state that must have been obtained by examination for one year or longer' from Alabama, Mississippi or North Carolina (grandfathered licenses excluded). The Mississippi licensee has the Mississippi State Board of Contractors send a verification of licensure directly to the Commission, documents one year of residential HVAC experience within the past five, passes the residential Business Management and Law exam through PSI, pays the $135 application and $220 license fees, files a credit report dated within 30 days, and posts a $10,000 surety bond before doing work over $5,000. That license covers residential work over $500 only.

The waiver applies to the residential specialty license, not to the Mechanical Contractor license; the latter requires the SC technical exam for Mississippi licensees.

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

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 Mississippi has nothing to transfer

Mississippi master HVAC technician

Licensed by cities and counties

Verified September 15, 2026· 11 sources

Mississippi does not issue a personal master HVAC license. The state-level HVAC credential is the Mississippi State Board of Contractors (MSBOC) contractor license: commercial 'Heat, Ventilation, A/C - HVAC' under the Mechanical classification (required on commercial jobs over $50,000; application and renewal $400, $300,000/$600,000 liability insurance, CPA-reviewed financial statement) or Residential HVAC (required for residential work over $10,000 in remodeling or $50,000 new construction; application $50, renewal $100). The license is issued to the business through a Certificate of Responsibility with a named qualifying party who passes the open-book PSI HVAC (or Residential HVAC) trade exam and the mandatory Mississippi Law and Business Management exam, so a master HVAC mechanic who only wants to work for an employer has nothing to transfer to at the state level; the personal master credential exists only in cities such as Southaven (Master Mechanical, $100, which itself requires an active MSBOC license, a $10,000 bond and liability insurance) and Gulfport (Mechanical/HVAC contractor license issued to the qualifying party, $100). MSBOC waives its HVAC trade exam, for $50 per exam, for qualifying parties who have held a license for at least one year with the Alabama Board of Heating, Air Conditioning and Refrigeration Contractors, the Alabama General Contractors Board, the Louisiana State Licensing Board for Contractors, the Ohio Construction Industry Licensing Board (HVAC or Refrigeration), the South Carolina Residential Builders Commission (Residential HVAC) or the Tennessee Board for Licensing Contractors, provided the license was obtained by that board's exam and there has been no disciplinary action in the period stated in each agreement; the Business and Law exam is never waived. EPA Section 608 certification is a separate federal requirement.

How local licensing works in Mississippi

State contractor license (business). MSBOC issues commercial and residential contractor licenses to companies through a Certificate of Responsibility. The commercial HVAC classification ('Heat, Ventilation, A/C - HVAC', with Ductwork, Refrigeration and Boiler specialties) requires the PSI open-book HVAC trade exam and the Mississippi Law and Business Management exam taken by the qualifying party (owner, officer or responsible managing employee), a $400 application fee ($400 annual renewal, $100 per additional classification), general liability insurance of $300,000 per occurrence / $600,000 aggregate naming MSBOC, and a CPA-reviewed financial statement showing net worth of $50,000 for a major classification or $20,000 for a specialty. Residential HVAC and Residential Mechanical (HVAC plus plumbing) licenses require the Residential HVAC (and Plumbing) exam and the Law and Business exam, a $50 application fee ($100 per additional classification, $100 renewal), proof of liability insurance with no minimum, three reference letters and documented experience in the classification.

MSBOC exam waivers for out-of-state qualifying parties. Reciprocity waives the trade exam only ($50 per exam waived, plus a $25 verification fee) after the origin board completes MSBOC's Reciprocity Verification Form; the applicant must have held the origin license for one year and passed that board's exam. HVAC waivers are available for the Alabama Heating and Air board (current license, Alabama exam), the Alabama General Contractors Board (HVAC can be waived; no discipline in the last year), Louisiana (HVAC can be waived but not mechanical or plumbing; the formal agreement ended but MSBOC continues to recognize Louisiana scores), Ohio CILB (HVAC and Refrigeration; no discipline in the last year), the South Carolina Residential Builders Commission (Residential HVAC; no discipline in three years) and Tennessee (all exams, the only state whose mechanical and plumbing exams are waived; no discipline in the last year). Arkansas, Florida, Georgia, North Carolina and the South Carolina Contractors Licensing Board agreements do not cover HVAC. Everyone takes the Mississippi Law and Business Management exam.

Southaven. Master Mechanical license ($100) for the license qualifier: application, photo ID, certificate of liability insurance, $10,000 surety bond in favor of the city, an active MSBOC contractor's license certificate and the company EIN. An out-of-state contractor without an MSBOC license must instead provide a letter of good standing from a municipality where its license is active and may not take residential projects or commercial projects over $50,000; the city defers to MSBOC on reciprocity.

Gulfport. Mechanical/HVAC contractor license ($100, waived with an MSBOC Certificate of Responsibility) issued in the name of the qualifying party: notarized application, current MSBOC license if held, five reference letters (waived with an MSBOC license), $100,000/$300,000 public liability insurance naming the city, home-jurisdiction privilege license and photo ID.

Out-of-state holders. A master HVAC licensee from another state who wants to contract in Mississippi applies to MSBOC as the qualifying party of a business, uses the exam waiver if the origin board is on the list, and then registers with each city; a master who only wants employment needs no state license and, in most cities, no personal card.
