Colorado has no statewide HVAC license — requirements are set entirely by local jurisdictions. Contractors must verify licensing rules with each city or county where they intend to work, as requirements vary significantly.

Reciprocity agreements can change. Always verify current status directly with No state issuing body — local city/county offices govern licensing before relying on reciprocity for licensure.
Colorado is one of the most prominent "local-only" states. Denver, Aurora, Colorado Springs, Boulder, and Fort Collins all have separate licensing regimes. There is no state-level HVAC contractor or technician license. Contractors working across multiple Colorado jurisdictions may need separate local licenses for each.
EPA 608 Certification — Required in All 50 States
Regardless of Colorado's state licensing rules, any technician who purchases, handles, or works with regulated refrigerants must hold EPA Section 608 certification. This is a federal requirement under the Clean Air Act that no state law can waive. EPA 608 Universal (covering Type I, II, and III) is the most versatile credential for most HVAC roles.
