Section 608 Certification for Air Conditioning and Refrigeration


Section 608 of the Federal Clean Air Act requires that all persons who maintain, service, repair, or dispose of appliances that contain regulated refrigerants be certified in proper refrigerant handling techniques.

The EPA has also placed a sales restriction on refrigerants, limiting the sale of regulated refrigerants to certified technicians only.

EPA Certification Exam Format
