A temperature conditioning system includes a damper system that determines the pattern of airflow through two coil slabs of an indoor heat exchanger, wherein the heat exchanger is preferably part of a split-system air conditioner or a heat pump. In a normal mode position, the damper system directs the airflow in a parallel flow relationship through the two coil slabs for optimum capacity and efficiency. In an enhanced mode position, the damper system directs the airflow in a series flow relationship through the two coil slabs. The enhanced mode position not only helps reduce humidity when the temperature conditioning system operates in a cooling mode but also helps raise the supply air temperature at a room register when the system is operating in a heating mode. In some embodiments, the damper system is also movable to a bypass position that allows the air to bypass the indoor heat exchanger.
