Wyoming to New Mexico: master HVAC technician license reciprocity

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

Wyoming 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.

Wyoming master HVAC technician

Licensed by cities and counties

Verified September 15, 2026· 12 sources

Wyoming issues no master HVAC, mechanical or refrigeration license and no HVAC contractor license; the State Fire Marshal's electrical program is the only state trade licensing, and its LM-H Limited Technician license covers only HVAC electrical wiring. The master-level credential exists only in city ordinances: Cheyenne's Master or Qualified Supervisor license for HVAC and refrigeration (8,000 apprentice hours plus 6,000 journeyman hours and an ICC/NICET/NASCLA exam), Casper's Mechanical Master (apprenticeship or four years plus five years as a journeyman or master, ICC G29-N), Laramie's master mechanical, refrigeration or gas service certificate of qualification (three, two and two further years respectively, city exam), and Gillette's Master HVAC Mechanical license (five years of approved experience plus the ICC exam). In each of these cities a contractor doing HVAC work must employ or be a master (Cheyenne 'qualified supervisor or master', Gillette and Casper 'Master of Record'), and the contractor license itself is a separate business license with fees ($200-$300 initial in Cheyenne and Casper, $150 in Gillette) and insurance. Rock Springs registers contractors for $125 with proof of insurance and tests no one. No city publishes reciprocity with other states' master HVAC or HVAC contractor licenses; Casper and Gillette reciprocate only with other Wyoming jurisdictions, Cheyenne's Board has discretion but no partner list, and Laramie may waive its exam for a certificate from any governmental agency whose exam is judged at least equal. A master arriving from another state should expect to present or take the ICC National Standard Master Mechanical exam (G29-N) and apply separately in each city.

How local licensing works in Wyoming

How local licensing works. There is no state HVAC board; each city's ordinance defines its own master-level license and the contractor license it qualifies. The reciprocity statute the cities cite reaches only other Wyoming jurisdictions.

Cheyenne. A Master or Qualified Supervisor license (12.1.8) requires 4 years/8,000 hours documented as an apprentice (or certified equivalent training) plus 3 years/6,000 hours as a journeyman, all third-party verified, and passing results on a current ICC, NICET or NASCLA exam from the Board's list. Fees are $50 application plus $50 initial and $25 renewal. Every HVAC (C1) or Refrigeration (C1) contractor must employ a master or qualified supervisor full time, who may represent only one contractor and is responsible for all its work; the C1 tested contractor license costs $50 + $200 ($75 renewal) and requires workers' compensation and liability insurance. Refrigeration licenses require EPA Type II, III or Universal certification. Reciprocity is at the Board's discretion (3.3.2/3.5.2) with no published state list.

Casper. Mechanical Master ($75 new, $37.50 renewal) requires a federally recognized apprenticeship or four years in a Casper-licensed mechanical shop plus five years as a journeyman or master, and proof of passing ICC G29-N or equivalent; a Mechanical Contractor license ($300/$150) covers heating, ventilation, air conditioning, refrigeration and sheet metal and requires $250,000/$500,000 liability insurance. Reciprocal licenses are limited to other Wyoming jurisdictions.

Laramie. Master certificates of qualification in mechanical (3 years after journeyman), refrigeration (2) and gas service (2) are issued after the building official's exam ($5 per attempt), or without exam on presentation of a certificate from another governmental agency whose exam the board of examiners finds at least equal. All work under a Mechanical, Refrigeration or Gas Service Contractor license must be performed by or under the supervision of the corresponding master certificate holder.

Gillette. Master HVAC Mechanical license: five years of approved experience and ICC exam results, $50 annually; Master Refrigeration Technician additionally needs ESCO/EPA 608 certification. A Class D HVAC Mechanical Contractor ($150 new, $50 renewal, $5,000 bond) must name a full-time Master of Record able to reach any job site within 48 hours. Reciprocity (5-III-1(d), since July 1, 2024) is for other Wyoming local-government licenses only.

Rock Springs. Contractor registration only ($125 plus insurance certificate); no master license or exam.

Out-of-state holders. None of these cities names any other state as a reciprocity partner. The ICC National Standard Master Mechanical exam (G29-N) is accepted by Cheyenne, Casper, Laramie and Gillette, so an out-of-state master who holds an ICC certificate can apply directly with verified experience; one licensed on a state-specific exam should plan on taking the ICC exam, except in Laramie where the board of examiners may accept an equal exam from another agency.
