Thanks Pete. I was not aware that Freon was so harmless, and thought it
might be toxic. My intent is to have the coils replaced, but just not right
now (cost for one thing, and also it isn't leaking that bad).

Many of the replacements for Freon are more toxic and less efficient
than the Freon was.

If the location of the leak can be determined it may be possible to
evacuate the system, braze the leak shut and recharge the system. I've
seen it done on a large computer room A/C unit where the leak was caused
by a line rubbing against part of the frame as opposed to corrosion. The
lines were otherwise sound and the line was secured so it couldn't rub
again.
