Section 608 Certification Overview

EPA Section 608 of the Clean Air Act mandates certification for all technicians who service, maintain, or repair refrigeration equipment. Rooted in the 1987 Montreal Protocol, the regulations prevent ozone-depleting refrigerants from being vented into the atmosphere. Technicians must pass the Core section plus at least one Type to be certified. Exams are administered by EPA-approved proctors such as ESCO Institute and Mainstream Engineering. Universal certification covers all equipment types with no restrictions.
