You are right in your assessment that I am not an A/C expert. I am quite handy mechanically and do most of my own work. This, however, is out of not only my ability level but my understanding level as well.

Please clarify: It appears that you are saying that through normal usage you lose 1/8 pound per year. Then you say that mine is due to a leak. When you say "leak", do you mean that which normally exists and seeps out or a "leak" that must be repaired? Or, do you mean both?

In such a repair, do I just lose the R12 that is in there now?

Thanks
