However, the restriction does not apply to air-conditioning equipment or components refrigeration classified as R-22 or to the resale of these refrigerants that are used in window air conditioners and similar units.
Technicians certified to service air-conditioning equipment and stationary refrigeration equipment by a Section 608 EPA-certified testing organization can purchase any type of ozone-depleting refrigerant with the exception of cans containing less than 20 pounds of R-12.
