As far as oil, floating around on the BB (I know, it's down right now) there
is a FAQ about the York compressors.  One of them being how much oil it
takes and how to check it.

As far as that goes.  If you are switching to R-134a, it'd be a good idea to
get the compressor rebuilt with new seals.  Apparently the seals differ from
R-12 and R-134a... anyway, you don't *have* to get new seals on the
compressor, but it'll reduce the possibility of leaks.  Get new hoses made
and you'll need a new vapor canister (it has silicone in the bottom to
remove moisture and once it's used up you need a new canister for the fresh
silicone).  If you can get a bitter condenser, it'd help the R-134a keep you
cool, but you don't *have* to do that.

Oh, and the oil you use differs between R-12 and R-134a, so make sure you
use the right kind (R-134a oil is probably a lot easier to find anyway).

Run down:  any seals need to be new and 134a compliant as well as the oil
and hoses.

That's it for now, off to work in a few, I'll try to get a peek to see if I
have anything that might help later...
