Depending on the brand and age of the equipment, on a 5 ton package unit you can expect roughly 80-100lbs of copper/aluminum coils.
About 8-15lbs of #1 copper
2 electric motors, about 25lbs total
1 compressor, 100+lbs
A couple lbs of wire
approximatly 200-300 lbs of metal
and a few other items like a cast aluminum gas valve (1lb), small contactor (2-4 of them), and a circuit board.
The prices you get for the variuos metals will greatly impact weather its worth it or not.
Note that this is just a rough estimate, and also note that as the tonnage goes down the weight of the metals will be reduced drastically. Here i could make money off the 5 ton units, but you will lose money or break even after a lot of work buying a 2-3 ton unit for $90
