At least one door covers the screen to control input of outside air providing quiet, economical ventilation without running the air conditioning unit fan motor. The frame, screen and door are extendible and retractible to fit different width windows. In one embodiment, the device is located between the air conditioning unit casing and a window sash. In another embodiment, additional frames, screens and doors are located between the sides of the casing and the window jambs.
