R-12

Better known as Freon, R-12 is an awesome refrigerant used in automotive air-conditioners and refrigeration applications. If you happen to own/drive a vehicle with an air-conditioner that is factory charged with R-12 Freon, and the systemworks good and does not leak, DO NOT UNDER ANY CIRCUMSTANCES MESS WITH IT. Pretty much any vehicle manufactured prior to 1993 is guaranteed to have an R-12 A/C system, but some 1993 vehicles came with the new stuff. It all depends on the manufacturer. Any vehicle manufactured prior to 1993 is guaranteed to have an R-12 air-conditioning system from the factory, with some exceptions. I have seen 1993 vehicles with R134a and early 1994 vehicles with R-12. Dichlorodifluoromethane (R-12), is a colorless gas, and usually sold under the brand name Freon-12, is a chlorofluorocarbon halomethane (CFC), used as a refrigerant and aerosol spray propellant. Complying with the Montreal Protocol/Clean Air Act, its manufacture was banned in the United States along with many other countries in 1994 due to concerns about damage to the ozone layer. R134a is R-12's replacement, and has been used in automotive and refrigeration applications since 1994-1995. You will begin to realize that R-12 is the superior refrigerant when you are idling in a parking lot or stuck in a traffic jam. While an R-12 system will almost always blow cold air no matter what, R134a begins to blow merely cool air when the vehicle is not moving.

True stories of R-12's superiority:

The A/C in my dad's 1983 Toyota Celica was absolutely freezing! Gotta love that R-12! The air-conditioner in my mom's 1990 Toyota Camry was the same way, as was the A/C in my dad's 1992 Dodge Dakota, and in his 1993 Chevy S-10 Blazer. R-12 is just a far superior refrigerant to R134a.

A friend of mine put some cans of soda in his old 1980s fridge that uses R-12, and the soda got so cold and frosty that some of the cans actually burst!

The sensation of bashing the space bar is satisfying. Otherwise, you are bored. Good luck curing it. You're too deep in.

R12

R12 was a planet in the Star Wars comic series. R12 was best known for producing a unique gas, also called R12, that was the most potent refrigerant known to the galaxy. R12 gas became obselete when the planet R12 was destroyed by the Death Star.

<Han Solo> Quick, Chewie, grab a can of R12 and recharge the A/C system.
