Have a lightly used Coleman Mach that I replaced after only a couple years (It actually began dying the first year). It sprung a leak shortly after I purchased the camper, and all the make-it-cold stuff eventually came out. I've looked around and found a few pages about repairing these things. Apprently, installing one of those "saddle" valves after the repair is made almost always end up leaking. So soldering in an low pressure valve is the "proper" way to repair these otherwise unrepairable units.

I am not a professional HVAC tech, but I think ScottG is over reacting.
Brazing in an appropriate low side port does make a proper torch and the skill to braze. If you are going to add a low side, you might as well add a high side. Now you need to buy the correct gauge set and a vacuum pump. Now find the leak.
The Harbor Freight Gauges and vacuum pump work, but they don't seem to last a long time.
I am lucky in that I have a neighbor who's son is a pro. If I do the hard work, he will do the "technical" part.

If it has sat in an empty condition then it's toast. They need to be fixed quickly otherwise moisture is obsorbed into the system and forms acid when it mixes with the remains of the freon. Then it destroys everything in its path.

What year A/C? Old may take R-22 Freon, newer 134A Freon. Easy to solder new valve to charge system. You will need a vacuum pump and a A/C manifold gauge set. Any quality A/C guy should be able to repair. About $140.00-$250.00 estimate. Any remaining Freon can not be emptied in the atmosphere. If you do the work, wear safety glasses.-Good Luck
