Motor Vehicle Air Conditioning (MVAC) System Servicing

Section 609 Technician Training and Certification Programs

CAA Section 609 requires that any person who repairs or services a MVAC system for payment must be properly trained and certified by an EPA-approved program. See list of programs.
Section 609 Certified Equipment

Section 609 requires that Technicians use refrigerant handling equipment that has been certified by the EPA or an independent standards testing organization.
Significant New Alternatives Policy Program (SNAP)

The Significant New Alternatives Policy Program (SNAP) was established under Section 612 of the Clean Air Act for EPA to identify and evaluate substitutes in end-uses that have historically used ozone-depleting substances.
Regulating HFCs under the AIM Act

EPA is managing a phasedown of hydrofluorocarbons (HFCs), a class of chemicals used as substitutes for ozone-depleting substances, under the AIM Act. Learn more about HFC reduction.

Motor vehicle air conditioners use refrigeration to cool the driver's or passenger's compartment. Learn more about EPA requirements for servicing these systems, and how these requirements impact service technicians, shop owners, and some refrigerant retailers. Most of these requirements come from regulations under section 609 of the Clean Air Act (CAA), while two additional sections of the CAA, 608 and 612, play smaller roles. The use of hydrofluorocarbons (HFCs) and their substitutes are also regulated under the American Innovation and Manufacturing (AIM) Act.
