An air handling system for supplying one or more zones with airflow. The air handling system generally includes a cold air damper, a hot air damper, a fan, and a controller. The cold air damper is associated with the one or more zones, and is movable between an open position and a closed position. The hot air damper is also associated with the one or more zones, and is movable between an open position and a closed position. The fan is positioned upstream of the cold air damper and the hot air damper and operates at varying speeds to generate the airflow for the one or more zones. The controller modulates the speed of the fan to maintain the cold air damper in an approximately fully open position or an approximately fully closed position.
