R134a, R12 is no longer available if you system has no major leaks, ask around local shops for r12. there's still some out there.
R12 And if you still have this change over to 134a instead of buy r12
The cost of R12 varies a great deal. The use of R12 is illegal in some places and requires certification in others. It is estimated that a pound of R12 currently costs approximately $20 US dollars.
no you can't. you must have the r12 removed and compressor oil then the valves need to have adapters installed so you can recharge the system no, but there are replacement freons (hot shot 414B) that can be added safely, after you empty the r12, and perform as the 12 did
CFC is Cloroflurocarbon and it refers to the Clourine, Flourine, and Carbon that are present in Freons such as R12. Most home AC units use R22, which is a HCFC, that is HyrdoClouroFlouroCarbon. Any Freon that starts with R requires a EPA license to purchase, and any that ends in A (such as 410A or 134A) is available to the public.
R12, if still available at your local parts store (requires a license), is very expensive. It is cheaper to retrofit the system to use r134a.
The 1992 Oldsmobile Cutlass Supreme uses R12 freon and needs 36 ounces. R12 is no longer being made, but is still being recycled and is still available through online auctions.
It came from the factory with R12. Due to the cost of R12 I suggest you have it converted to run on R134. Have the leak fixed and convert it to R134 and save yourself some big money. R12 is no longer in production, and is very, very, expensive.
how to convert r12 to134r
It originally came with Freon (R12). Unless it has been converted then it will still contains R12. I suggest you have it converted to R134a, as Freon is so very expensive and hard to find.
It is still possible to aquire R12 Freon, but the cost is excessive. My advice is to convert the system to R134a.
will r 134a work in home ac. No it will not. 134A is strictly for vehicles and replaced R12 as the preferred refrigerant, since R12 is no longer manufactured due to it's harmful effects on the enviroment.
