ABSTRACT:
Within the vent system of an air conditioning unit or the heating system at least one flap is pivotably mounted such as to be moveable between a closed position blocking flow through the conditioned air vent, and an open position allowing conditioned air to pass through the vent and into one or more rooms to be serviced by the conditioned air. One or more stops are provided to cease pivotable movement of the flap when the open position is reached. Preferably more than one flap is utilized. Preferably gravity is utilized to bias the flap into the closed position so that when the heating or air conditioning blower is turned off the flap will return to the closed position. The flap is also moveable manually between the open and closed positions, thereby a room or rooms which are not to be heated or cooled may be blocked off from the air conditioning or heating system by the manual closing of the flap.
