Mississippi to Texas: master HVAC technician license reciprocity

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

Mississippi 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 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.
