Minnesota 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.

Minnesota issues no master HVAC, master refrigeration or HVAC contractor license. The only statewide requirement is the $25,000 mechanical contractor bond that a business files with the Department of Labor and Industry (DLI) under Minn. Stat. 326B.197 ($100 filing fee, valid two years) before contracting for gas, heating, ventilation, cooling, air conditioning, fuel burning or refrigeration work; DLI states that there is no state license for mechanical contractors or their employees and that cities may require licensure or a competency card. The master-level credential therefore exists only at the city level: Minneapolis issues Master Warm Air Ventilation and Master Refrigeration Certificates of Competency (four years of experience and education plus an ICC exam) and requires a master card holder behind each HVAC Class A or Refrigeration Systems Installer contractor license; Saint Paul issues Master Warm Air, Ventilation and Refrigeration competency cards and requires one for each Warm Air/Ventilation business trade license; Rochester licenses individual HVAC Master Installers after a city certificate of competency; Bloomington licenses mechanical contractors on a Minneapolis or Saint Paul card or its own test. An out-of-state master HVAC or mechanical contractor license has no state-level recognition and none of these cities publish a path that accepts it; Minneapolis and Saint Paul recognize each other's master cards. Federal EPA Section 608 certification is separately required of anyone handling refrigerants.
