Mississippi to New Mexico: master HVAC technician license reciprocity

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

Mississippi does not issue a statewide master HVAC technician license, so there is nothing to transfer. Here is New Mexico'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 mechanical contractor (all states)

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

An out-of-state master HVAC technician or mechanical contractor receives no exam waiver in New Mexico. The applicant files the qualifying party application with PSI ($36) and a notarized work-experience affidavit showing four years of experience in the MM-3 classification within the past ten years (out-of-state experience is accepted), then must pass the 100-question MM-3 trade exam ($68.88, 75% to pass) and the Contractor's Business and Law exam ($68.88) or complete a commission-approved business and law course in its place. Once the certificate of qualification is issued, the individual or business applies for the MM-3 contractor's license ($30 application; $50 per year or $100 for the two-year term, or $100 per year for MM-98) and must carry workers' compensation coverage. Anyone who personally services refrigerant-containing equipment also needs federal EPA Section 608 certification, which CID requires of JR journeymen.

CID's pages describe no substantial-equivalence or endorsement review for contractors from any state; the statutory reciprocity authority in NMSA 60-13-14(C) has not been exercised for mechanical classifications as far as any official page shows. A qualifying party may also obtain the parallel JR journeyman certificate without new work-verification forms.

How New Mexico licenses master HVAC technicians

New Mexico master HVAC technician · “MM-3 HVAC Contractor (qualifying party certificate of qualification)”

Statewide license

Verified September 15, 2026· 5 sources

Issued by New Mexico Construction Industries Division (Regulation and Licensing Department), Mechanical Bureau; applications and exams through PSI

New Mexico has no 'master HVAC' license. Its highest heating and cooling credential is the MM-3 Heating, Ventilation and Air Conditioning contractor classification (install, alter, repair, service and maintain HVAC air-handling and refrigeration equipment, piping and ductwork, with controls at 24 volts or less); the broader MM-98 Mechanical classification covers MM-3 plus plumbing, gas fitting and process piping. CID issues the contractor's license to the contracting entity and a personal, non-transferable certificate of qualification to the qualifying party, the individual who passed the MM-3 trade exam and the Contractor's Business and Law exam, so this site maps the MM-3 qualifying party to the master level. A qualifying party needs four years of experience in the classification within the ten years before application. Even with an MM-3 license the hands-on work must still be done by or under a certified JR or JSM journeyman. CID publishes reciprocity only for EE-98J electrical journeymen; no reciprocity or exam waiver is published for mechanical qualifying parties or contractors, although NMSA 60-13-14(C) allows the division to enter into reciprocal agreements with states having equivalent requirements.

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.
