EPA Section 609 Certification Test
The EPA Section 609 Certification Test is the examination component of the federally required credential for technicians who service motor vehicle air conditioning (MVAC) systems. Administered through EPA-approved providers such as ASE, ESCO, and MACS, the test verifies a technician's knowledge of refrigerant handling, recovery and recycling procedures, leak detection, and Clean Air Act regulations. The exam format varies by provider—ESCO offers a 50-question open-book test requiring 84% to pass, while ASE uses a 30-question quiz requiring 24 correct answers. Passing the test earns a lifetime certification that is required to legally service MVAC systems and to purchase small containers of automotive refrigerant.
