Obviously many of you do not understand how an AC system works.
It is a closed system. The AC unit does not draw out side air in or vent inside air out. There is no AC vent to draw outside air in or to expel out to the outside...it only cools the interior air. It draws inside air into the unit, cools it, and then sends it back out into the area it's cooling. This is a simplified explanation as I won't go into details on condensers, compressors or evaporators.
When using your AC (house, car, rv) keep all vents, windows, and doors closed.
