Technicians who seek EPA refrigerant certification may acquire study materials from Video General Incorporated. Experience is not a requirement for taking the certification tests, but inexperienced testing candidates should consider using the study materials offered by Video General Incorporated or another EPA-approved testing organization.
The candidate for refrigerant certification must pass a CORE section of the test, which includes topics such as ozone, refrigerants, safety and the Clean Air Act. Upon passing the CORE, the candidate can register for a testing session, which is available throughout the year.
Test candidates must decide their levels of certifications, which are authorized by Section 608 of the Clean Air Act, based on skills ranging from working with residential appliances to installation and repair of large, commercial refrigeration systems.
