The duct, or air distribution, system used in cooling and heating your home is a collection of tubes that distributes the heated or cooled air to the different rooms. Typical duct systems lose 25 to 40% of the heating or cooling energy put out by the cooling and heating system. Learn about common problems and ways to get the most out of your duct system.
