EPA Section 608 certification is required by federal law for technicians who service, maintain, or dispose of equipment containing regulated refrigerants. It is administered under the Clean Air Act.

Type I (small appliances ≤5 lbs of refrigerant), Type II (high-pressure equipment), Type III (low-pressure equipment), and Universal (all three). The Core section is required for all types.

No. Once obtained, EPA 608 certification is valid for life and does not require renewal — though it can be revoked for violations.

The Core section contains 25 questions. Each Type section (I, II, III) contains an additional 25 questions. To earn Universal, you must pass Core plus all three Type sections.
