Wyoming to Alaska: master HVAC technician license reciprocity

Alaska has no master HVAC license; its highest person-held HVAC credential is the Mechanical Administrator license issued under AS 08.40.210-08.40.490 by the Division of Corporations, Business and Professional Licensing (CBPL), which is treated here as the master level. It is a supervisory license: a person may not act as a mechanical administrator without it, every registered mechanical contractor must hold or employ one, and the administrator is responsible for all mechanical work done under the contractor's license (AS 08.40.260, 08.40.280; 12 AAC 39.902). The license is issued in categories; the HVAC-related ones are Unlimited HVAC/Sheet Metal (UHVCS), Residential HVAC (RHVC), Unlimited Refrigeration (UR), Heating, Cooling and Process Piping (HCPP) and Mechanical Systems Temperature Control (CNTL), with plumbing categories (UCIP, RPHH) alongside. Qualification is by experience (for example four of the last six years as a journeyman or field superintendent in HVAC and sheet metal work for UHVCS, or two of the last four years as a journeyman for UR and RHVC, where a year means at least 1,500 hours) plus a PSI-administered examination passed at 70% within the prior 12 months, or by credentials for administrators licensed in another state. Fees are $150 to apply plus $200 for the license ($350); the license is biennial, expiring December 31 of odd-numbered years, and renews for $200 with an eight-hour Uniform Mechanical Code workshop per category. The administrator license does not by itself let the holder install fuel gas piping (that needs a DOLWD Plumber Gas certificate) or original control wiring (that needs an Electrical Administrator), and anyone handling refrigerants needs federal EPA Section 608 certification.

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.
