Nevermind, it's out of the window, in a safe spot still quietly
hissing. I suppose it's the Freon. Time to buy a new unit, next summer.

I just clumsily drilled through something in the AC unit. I can tell
because there is some hissing sound as if gases being released. It's
on the outside, but maybe I should take the AC out of the window.

Thanks.
