Problem with my air-conditioning (Summer approaching )

[celica2004]

Hi there,

I got a 1993 tyota corolla in which air-conditioning system doesnt work. When I checked with a mechanic he said that i need to fill in new freon as the old one got leaked out. He said that for 1993 corolla refilling freon is expensive than the for the recent models ( As something to do with environment and new standards...)

Please suggest me what kind of freon that i need to get and mention its price.. Can i recharge that by myself ? if so please let me know the procedure.

All your answers are highly appreciated.

Thanks,
new corollate.

Check under the hood to see what kind of AC refrigerant your car uses. Its either a white or blue sticker. If its white, your car most likely uses R-12. If its blue, R134a. R-12 is very expensive, and you need to be licensed to buy/repair AC that uses this type. R-134a is pretty cheap, and can be bought at any automotive store (even Target has some). I would suggest taking it to a shop, since you don't know if your AC system is leaking.

Your car has the old FREON system, which is bad for the environment.. you will have to convert to the new R134 system if you wanna keep using your AC, unless you can find someone to fix it and refill with FREON.

The R-12 refrigerant was used until 1994 or 1995. Chances are that your car uses it. R-134a is supposed to be better for saving the gay gray whale or some stupid shit, but it does not cool as well as R-12. New cars that are designed to run on R-134a compensaste for this fact, but older cars can't. Unfortunately R-12 and R-134A are not compatable with each other. If they are mixed in the same system, they make a sticky mess. The production of R-12 has been banned, but it is still legal to sell refrigerant that has already been produced. That is what your mechanic is telling you. Since the amount of R-12 is limited, the price is high and only going to get higher. It was about $60 per pound last time I checked, and that was two years ago. If your system is empty, you will need 3-4 pounds. R-134a, on the other hand, is very cheap.

R-12 and R-134a cannot be used in the same system, but you can have your system FLUSHED and converted to R-134a. All that is necessary to convert it is to change the pressure fittings. This is probably what your mechanic will suggest. A flush and conversion will probably run you about the same amount as just refilling the system with R-12, so that would probably be the way to go. R-12 is just going to get more expensive, and if you have another leak all of the money you spent would be wasted if you refilled with it. Have the system converted and stay cool! Regards, Aaron
