According to the EPA, "Accumulated debris can restrict the air flow in your air ducts, making your system work harder to heat and cool your home.  A build up of .042 (1/20) inches of dirt on the heating or cooling coil can result in a decrease in efficiency of 21% increasing your monthly utility and fuel bills."
