You all were talking about compressors out of a/cs, frigs, whatever. How many of your "yards" make you drill a couple of holes in the bottom and drain out the oil? The place I take my non-ferrous takes "sealed units" (not sealed anymore the way he wants them!) drained or he won't take them (about twice the going rate of shred). I don't really mind it unless I hit one of the windings inside. That wakes me up a bit!!
