DUCT INSTALLATION
This method draws return air from specific points in the
house and supplies outside air to specific locations of
the house. This system is not connected to an air
furnace.
Return air ducts should be installed in areas of the
home where the poorest indoor air quality exists (bath-
room and kitchen). Supply air ducts should be installed
to all bedrooms and living areas.
