1. HVAC Contractor Requirements — local licensing only (no state license)

   Wyoming does not issue a state HVAC or mechanical contractor license. Contractor licensing is local: in Laramie, contractor licensing runs through the city's Code Administration division (307-721-5271), and mechanical permits are required for installations. Federal EPA Section 608 certification is required for anyone handling refrigerants. Any electrical work tied to HVAC installs requires a Wyoming state electrical license through the Department of Fire Prevention and Electrical Safety.
