Residential Duct Sizing Guide The following duct sizes are based on a fraction drop of inches per feet of lineal duct. This "Equal-Friction" method of duct sizing should be adequate for normal residential furnace heating and air conditioning applications. Larger volumes or higher static pressures should be dealt with on an individual. Residential Duct Sizing Guide Key Points to Remember when using this guide • The sizing chart is designed for estimating the airflow in an “average” system. • The chart assumes the blower motor and total effective length of the duct system to be adequate for a.1 friction rate.
