I'm not sure about the 1993 model but in the 2001 they don't have "Freon" (meaning R12) any more. The refrigerant is stored in that silver canister on the front left side of the engine-bay. R12 is expensive to replace. AC service providers are EPA licenced to service R12 & R134 systems, but they won't sell you the "stuff". So, you have to go to a service provider. I hope this helped. == 1993 Prizms still used Refrigerant-12, commonly known as "Freon". Later models use R-134. Refrigerant is distributed throughout the system. The excess refrigerant and oil is held in the drier/receiver. If you have a tight system and can afford it, stick with the R12. You will not regret it. Retrofit to R134 can be very problematic and expensive.
R134a
R134a
To buy ac Freon you need to be certified and to add ac Freon to central air conditioning unit is risky.The air conditioner filters are normally located in return duct grills or in the air handler. Read how to change air conditioner filters.
You shouldn't have to change freon, it doesnt go bad.
It takes R134a freon, that's it, no special type..........
NO
1993-95 for most.
No need to.
Why do you want to change the Freon? Not necessary and very expensive.
Never
Why would you want to change the AC freon? Buy a kit at Wal-Mart or auto parts comes with instructions
It was a bad answered that talked about changing the antifreeze -- not the airconditioning freon.
