i was wondering how much it would be to get an injection of freeon or if i would have to convert to the new stuff cuz of the age of the car. If i did have to convert how much would it be

 

Pretty much limited to a conversion to the 12 or 134a. Not sure on price, never personally done the conversion.

 

Not at all expensive. You can buy the 134 at a parts store along with the appropriate oil over the counter.R12 is a different matter at least in Oklahoma. Then have a shop reclaim the R12 or if its empty pull a vacuum on it and install R134. I don't think R134 cools as good as R12 but it is the best choice.

 

You shouldnt need an "injection" of freon unless you have a leak in the system. Refrigerants are not consumable. At least check into the cost of an R12 refill. It may not be as expensive as you think. If you wind up with a 134 conversion it may take some trial and error before the ac blows cold enough. It takes anywhere between a 70% and 90% charge of 134 to obtain the proper cooling in an R12 system. Most complaints about improper cooling with 134 are due to an improper charge. Not the refrigerant itself.

 

Freon is running @ $60 - $70/lb. It least that's what it was when I got a recharge about 2 yrs ago. Maybe up slightly from there. But the key is to fix the leak first. Otherwise your just throwing money out the window.

 

I'd recommend going to a shop first and have them run a dye through the system to check where the leak is. More than likely it's the compressor. If so, I think this is the most expensive part of the system. When you place a compressor, it's always a good idea to replace a few other select parts as well. If you're replacing 3/4 the cost of the entire system, might as well go all out and replace the rest for peace of mind.

Mine's still good but going out. When it finally dies, I'm going to buy all new components and convert to R134a.
