EPA 609 Technician Certification
Since January 1, 1993, any person, repairing or servicing motor vehicle air conditioners shall certify, to the EPA that such person has acquired, and is properly using, approved equipment, and that each individual authorized to use the equipment is properly trained and certified under Section 609 of the Clean Air Act. In addition, only Section 609 Certified Motor Vehicle A/C technicians can purchase refrigerants in any size container from an auto supply house for use in cooling the passenger compartment of vehicles, including containers of 20 pounds or less.
Motor Vehicle Air Conditioners (MVAC) are defined as mechanical vapor compression refrigeration equipment used to cool the driver or passenger compartments of any motor vehicle. This definition is NOT intended to encompass the hermetically sealed refrigeration system used on motor vehicles for refrigerated cargo or the air conditioning systems on passenger buses which use HCFC-22 refrigerant. Section 609 certification is required for working on MVAC systems while Section 608 certification is required for working on non-motor vehicle air conditioning systems. Note that Section 608 certification is required for working on hermetically sealed refrigeration systems used on motor vehicles for refrigerated cargo or the air conditioning systems on passenger buses which use HCFC-22 refrigerant.
Mainstream is approved by the EPA as a certifying agency for 609 MVAC Technician Certification and 608 Type I, II, III, and Universal HVAC Technician Certification Exams.
