I don't know if this has been done before, because because I rent, can not do any installation therefore a slip and window A/C is not an option for me and only portable is okay. But I heard that the portable is noisy.
So I wonder if it is possible to put the outside in the backyard (my window faces the backyard) and make some modification to the portable A/C by connecting the cold air to the hose through the window into the room.
Is that possible?
