R-12 "substitutes" are losers for a variety of reasons. Stability, compatibility with lubricants and seals, performance, and safety are some of the things compromised. Do a keyword search here, you can find out why. Or check out EPA literature for more info. Reputable A/C mechanics will not touch the stuff- they are really marketing gimmicks. They kid you into thinking that they will save you money, and that is not going to happen. If your system doesn't need repair, use R-12! But that is usually the sticking point- there must be a problem if you are considering substitutes.
You need to do some more leg work and at least take pressure readings. If you are not getting any cooling, it sounds like you have little or no refrigerant left in the system, and that alone can be a big job to fix. No matter what refrigerant you end up using, if you have a steady leak, the system has to be repaired. The best way to find and repair leaks is using hydrocarbon detection equipment. In other words, you will end up in an A/C shop anyway, why not make life easier and do it now?
Staying with the original R-12 system is an option if the system is leak-free. If you have to do any work on the system (leaks, compressor or expansion valve replacement, etc), it makes more sense to retrofit to R-134, a no-brainer. It should not cost you $1000 to retrofit, and if you have a leak, that will likely cost as much or more to fix than the retrofit!
