It's almost as if this broken AIR CONDITIONING UNIT was scaled to be a perfect fit for the ALCHEMITER all along.
WEIRD!
Author commentary: This here is a pretty dry joke about the fact that I intended to put the alchemiter on top of the AC unit all along. So when I was designing Dave's roof, I made sure to scale the AC block so that the device would fit perfectly on it when the time came. It's not like...a great place for the alchemiter? But it sure does fit, I'll give it that.
