A/C refrigerant question
So, my a/c needs to be recharged, and admittedly, a/c is a weak spot for me. I don't know what type of refrigerant I need.
Sometime in 2008 I had the a/c redone, new condenser installed etc. But I have no idea how to tell if it was converted for the 134 refrigerant or if its still set up for the old gas. Are there any easily identifiable components that I can check to determine which type of gas I need?
Thanks in advance.

If it is a '94 model it should have always been a R134 system.
The high and low pressure taps are totally different for R134 and for R12, also, there should be fairly prominent stickers under the hood to notify whoever that a conversion had been made.
On any system that has been converted from R12 to R134, the correct taps for the refrigerant that was used should have been left in place.

Good to know. I have no idea when they changed the gas requirements.
Someone had told me a while back that it was an R12 system and I would need to convert it if it hadn't been done already. But that was a parts guy at O'Reilly.
That makes it nice and easy to recharge the system. Thanks for the info.

if you paid less than a few hundred bones to get it serviced, then it was converted. IF someone has a license to buy r-12, they'd have to pay in the area of $50+ per pound for it so they'd prolly charge you $80 or more per pound.

I'm guessing it's a difference in size for the low and high pressure connections?
Would you guys happen to know the sizes for each? That way I can measure and check the tread count to determine the difference.

The R12 fittings are externally threaded.
The R134 fittings use a lock on system sort of like an air chuck, with different sizes for high and low pressure sides.
Both types have protective caps that screw onto them, the R134 type being threaded internally.
