Wyoming to Maryland: master HVAC technician license reciprocity
Wyoming does not issue a statewide master HVAC technician license, so there is nothing to transfer. Here is Maryland'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 without a reciprocal agreement
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
A master or contractor-level HVAC licensee from a state other than Delaware or Virginia must qualify for an original Maryland master license by examination; the Board's FAQ says reciprocal licensing is available only where an agreement exists. Bus. Reg. §9A-302(b) frames the 3-year requirement as employment under a Maryland journeyman-or-higher license under a master contractor, but §9A-302(g) lets the Board credit up to 6 years of HVACR work experience that does not meet that pattern when it provided comparable experience, and up to 3 years of formal study, so documented out-of-state experience can be submitted to PSI (which reviews eligibility for the Board) toward the master exam. The applicant passes the 100-question open-book master exam with 70% ($150), registers the license, pays the $94.50 license fee, and files a certificate of insurance ($300,000 general liability, $100,000 property damage) if they will contract work. Bus. Reg. §9A-305 authorizes the Board, by majority vote, to waive the exam for a licensee of any state that waives its exam for Maryland licensees to a similar extent, but the Board has published that waiver only for Delaware and Virginia. There is no separate law or business exam.
The Board's published materials do not say whether PSI accepts out-of-state journeyman-level experience toward the 3-year master requirement without a Maryland journeyman license; the PSI bulletin says an applicant who does not meet the standard master criteria may instead sit for a Master Restricted exam with 6 years of qualifying experience. The Board's fee page lists no separate application fee.

How Maryland licenses master HVAC technicians
Maryland master HVAC technician · “Master HVACR Contractor”
Statewide license
Maryland's highest person-held HVACR credential is the Master HVACR Contractor license issued by the Board of Heating, Ventilation, Air Conditioning and Refrigeration Contractors; it authorizes installation and maintenance in all areas of HVACR work and is the license under which HVACR contracting is done. The Board also issues Master Restricted (one or more areas: forced air, hydronic, ventilation, air conditioning, refrigeration) and Limited Contractor (maintenance and repair only) licenses. A new master must have been licensed as a journeyman (or journeyman restricted, limited or master restricted) and regularly and principally employed providing HVACR services under a master for at least 3 years, with 1,875 hours in the year before applying, and pass the PSI master exam (100 questions, 70%, 240 minutes, open book, $150); the license fee is $94.50. A master, master restricted or limited licensee who signs or approves HVACR contracts must carry $300,000 general liability and $100,000 property damage insurance with the Board as certificate holder. The Board reciprocates only with Delaware and Virginia; licensees of those states who qualify are licensed without the Maryland exam.
Why Wyoming has nothing to transfer
Wyoming master HVAC technician
Licensed by cities and counties
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.
