One of your customer reviewers mentioned venting the unit through a hole in the wall, because they had no window. Is venting necessary? Will this work without window or any other hole/portal?A. The Whynter ARC-10WB is required to vent outside as the back of the unit will produce heat when operating and in order to cool the room the hot air must be pumped outside.
How long is the window kit?A.
The Whynter ARC-10WB window kit is 38"
