How to get an HVAC license in Wyoming

Hours, exam, fees and renewal for HVAC work in Wyoming. Taken from official WY pages and checked .

Quick answer
  • Licensing body: No statewide HVAC/mechanical board — city/county licensing (statewide electrical LM-H covers HVAC wiring only)
  • State journeyman license: No (No statewide HVAC mechanical journeyman. Local mechanical cards + separate state electrical limited technician (LM-H) for load-side HVAC wiring.)
  • No statewide HVAC mechanical license — local + electrical wiring card: Mechanical HVAC work is licensed by cities/counties. Statewide, the Department of Fire Prevention and Electrical Safety licenses electrical work; LM-H limited technicians cover HVAC/refrigeration wiring on the load side of the equipment disconnect — not the mechanical trade itself.
  • Exam: see below, via Local ICC exams + DFPE for electrical limited
  • Code edition: Mechanical exams set by each city (Casper uses ICC G29-N/G31-N or equivalent). State electrical limited exams via DFPE/ICC for LM-H wiring scope.
