Where to get R-12 in a auto store?

R-12 is no longer available in auto stores or anywhere else due to its harmful effects on the ozone layer. The production and use of R-12 have been banned under international agreements, including the Montreal Protocol. This refrigerant has been replaced by more environmentally friendly alternatives, commonly referred to as R-134a and R-410A. For questions or concerns about refrigerants, it's best to consult certified professionals in the automotive or HVAC industries who are aware of the current regulations and industry practices.
