Most cars with air conditioning manufactured prior to 1995 used R12 Freon refrigerant, which is believed to damage the ozone layer. Due to environmental concerns R12 is no longer widely commercially available, having been replaced by R134a. An ozone friendly alternative, R134a is an efficient absorber and carrier of heat, and contrary to popular belief, most cars originally equipped with R12 can be converted to 134a and still keep you just as cool.If you have been putting off converting from R12 to R134a because of the time and hassle, our Classic Auto Air website offers detailed instructions that explain how to make the switch. Follow our step-by-step instructions, and if you get into a jam, just give us a call.
