CONVERTING MY FORD TO 134a
Until 1995, most cars with air conditioning used R-12 Freon refrigerant that is said to have a negative side effect of damaging the ozone layer and is no longer produced in most countries. since then, the industry standard has been R134a, which is an efficient replacement. Contrary to popular belief, most cars originally equipped with R-12 can be converted to 134a and still keep you just as cool.
