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.
At this time, we do not have a seminar to prepare you for the EPA exam. We are developing an online class as well as a home study guide. However, we do offer several training references to help prepare you for the EPA test. These references can be purchased individually or in a bundle.
