An air control system and associated methods including a flexible duct having air exit holes and a flexible liner sheet within the duct and extending longitudinally along the duct, the liner sheet having opposite longitudinal edges connected to the duct along the longitudinal length of the duct, the liner sheet being permeable in one aspect and regulating air flow through the exit holes when the sheet is pressed against the portion of the duct having the exit holes. The duct may also have multiple liner sheets arranged end-to-end and/or layered in various duct segments such that the different liners may be independently controlled to regulate the outflow of air from the duct as desired. The duct having a liner which closes or inhibits air flow from the exit holes may also be rotated to accommodate use of a single duct for different seasons and where the internal liner adjusts to assist with the downward control of air flow based on alignment of various perforations with the different exits holes.
