Mo@#$%^&* ..need A/C and Furnace replaced

A big sledge hammer will make small pieces of it. Be aware though some of the system may be covered in Asbestos.

I am well aware on how it has to come out, I just wished now I would have replaced it 20 years ago when I was in my early 30's. Cast iron shatters when hit with a hammer. An air chisel will tear cast iron up.
