EPA Certification, Test, Exam, and Review

To work on stationary air conditioners and refrigeration systems, you must be certified under Section 608 of the Clean Air Act.  Please note that the purchase R-410a and R-134a do not require EPA certification as they do not have any ozone depleting substances.

There are four types of EPA certification: Type I, Type II, TYPE III, and Universal Certification.

Type I Certification (Small Appliances) - This certification covers manufactured, charged, and hermetically sealed appliances with five pounds or less of refrigerant.

Type II Certification (High Pressure and Very High Pressure Appliances) - High Pressure appliances use refrigerant with a boiling point between -58°F and 50°F.  High Pressure refrigerants include 12, 22, 114, 500, and 502.  Very High Pressure appliances use refrigerant with a boiling point below -50°F.  Very High Pressure refrigerants include 13 and 503. 

Type III Certification (Low Pressure Appliances) - Low Pressure appliances use refrigerant with a boiling point above 50°F.  Some refrigerants included under this classification are 11, 113, and 123.

Universal Certification - An Universal Certification can be obtained and a candidate passes the certification exams for Type I, Type II, and Type III.

To become certified, technicians must pass a test demonstrating proper handling of ozone depleting refrigerants and knowledge of EPA refrigerant regulations.
