It Should Use R12, That Was Factory On Them. It May Have Been Converted. Either Let A Good A/C Person Check It Out.
R134a
R12 134A pre 1996 is r12, after is r134
No , it's R134-a
It came from the factory with R12. Due to the high cost of R12, I would have it converted to R134.
R134 _ Well Mine did
It came from the factory with R12. Unless it has already been converted which you will know by a sticker placed somewhere on the system, I would most definitely have it repaired and then converter over to R134. R12 is just too expensive to consider using.
This is the transition year. It can be R12 or R134. It is listed on the unit. The fact that R12 is no longer being produced makes it extremely expensive. Convert it to R134.
Unless it has been converted to R134, the OEM refrigerant installed in 1991 was R12 Freon. I suggest you have it converted to R134 if it has not already been done.
There is no need to ever change the refrigerant which is R134 and not Freon R12.
Uses no Freon which is R12. Uses R134 refrigerant.
R12 It is not produced anymore. Have to covert to R134.
You do not want to buy Freon as it is very, very, expensive. Have the leak repaired, the system purged of all Freon R12 and the oil. Have it converted over to R134 refrigerant. You cannot just add R134 as the oil used in R12 is not compatible with R134. You will be money ahead by converting it.
