Recharging Armstrong AC

[jfremstad]

My 1971 Ambassador has original A/C. It is an Armstrong TR21-12 CWD17 model.

I see from various threads that it can possibly be recharged. Does anyone have a diagram or picture of where to refill? Would an A/C guy know where to refill? I took the shroud off and found a spot that sort of looks like tire valve. Is that where the refrigerant goes? I have no intention of doing this myself, but I would like to point the service person in the right direction . . . . .

It is most likely a R-12 system. You will most likely have a hard time trying to find someone that will service R-12 as R-134 is whats legal today. The service fitting are different between the two. In the long run it may be cheaper and much easier to replace with a modern unit. You might get lucky though and find someone around that will still service the R-12 units.

IIRC, you might have R-22 in your Armstrong. If that is the case, any competent A/C service tech (not the RV tech type) can re-charge your unit.
