It is important that the exhaust-hose be sealed where it meets the window

to prevent the hot exhaust air from re-entering the room, which would

increase cooling time. For me, this meant cutting up some corrugated

cardboard to fit, and stuffing some Kleenex in the gaps left over. The

units came with some hardware to seal-off the exhaust hose, but this

hardware didn't fit my windows, hence the cardboard.

I have 2 single hose AC units (8&12BTU)...the larger cools 2 rooms (625sf) comfortably. It wouldn't run in a standard 15A outlet though, I had to re-wire a dryer outlet so it had its own circuit. We have crank-out windows! 8^O
