No Statewide License -- But Local Rules Apply

Wyoming does not have a statewide HVAC contractor license. However, many cities and counties require local contractor licenses, business licenses, and permits. Always check with your local building department before starting work.

What You Still Need Everywhere in Wyoming

  • Local Business License -- Required by most cities and counties
  • Building Permits -- Required for most HVAC installations; apply through local building department
  • General Liability Insurance -- Required by most commercial clients and advisable for all work
  • Workers Compensation -- Required if you have employees

Major City Requirements

Cheyenne, Casper, and other Wyoming cities may require local permits and contractor registration. Check with your local building department before starting work.

EPA 608 Is Still Federal Law

Even without a state license requirement, EPA Section 608 makes it illegal to purchase refrigerant containers over 2 lbs or vent refrigerants without EPA 608 certification. Complete our free EPA 608 study course.
