I would like some thought on this. My car is a 90 vert. and yesterday I hit 30000 on miles. The car has the org. ac system and it works perfect. The question is, It has R-12 in it. Should I talk to a shop to change it to 134 before something goes wrong or just use it like normal until something breaks. My thought was at the cost of R-12 maybe a company would want to recover the R-12 and do the swap at no charge.

I have heard that R12 is no longer available because the sale of R12 has been made illegal. I don't know how true that is.
Several years ago I ran low on freon and went to an AC shop. The guy wheeled out this cart with a label that said R134. I told him it was R12 and he wheeled out a different cart and recharged it.

It IS illegal to manufacture it. that's why prices went up, the supply that currently exists, is all that there will ever be.

Get your license here: www.epatest.com and buy all the R12 you want. It'll still be cheaper than anything else you do when it comes to rebuilding it. Keep an eye on the hood above the compressor. The shaft seal on the Nippodenso compressor is usually the first thing to go, especially after 10 years. If you see compressor oil, time to fix it. Seal kits are about 50 Bucks, but you'll need to empty it and replace the Accumulator, as well as check for junk in the orifice,
