<human>: We have 2 window AC units in the house, and both had not been cooling that great lately.  So I cleaned the filters out of both units and the smaller of the two immediately begins to work better.  The larger of the units did work a bit better, but still wasn't cooling that great.  I noticed that there was a pool of water inside the unit that wasn't draining properly.  Having already maxed out the tilt I could do to the window unit long ago, I decided to drill a hole in the bottom of the unit to drain the water.

I drilled one hole in the center where nothing was and the water poured out.  So far so good.  Then I decide to make the actual drain hole bigger.  I drilled too far and put a hole through the chassis and into the AC condensor spewing R-22 (or it's equiv) into the air, destroying the unit instantly, and about 60% of the house's cooling ability.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: TIFU by deciding to fix my AC units and I destroyed one with a drill.  I should have gone drinking instead.
