EPA 608 Certification — Required in All 50 States
Regardless of Iowa'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.
