In a split-system central air conditioner, an outdoor cabinet contains the outdoor heat exchanger, fan, and compressor, and an indoor cabinet contains the indoor heat exchanger and blower. In other words, don't use the system's central fan to provide air circulation - use circulating fans in individual rooms.Ī central air conditioner is either a split-system unit or a packaged unit. If you have a central air system in your home, set the fan to the 'auto' mode. But in both cases this will increase energy use, both for the dehumidifier itself and because the air conditioner will require more energy to cool the house. In those instances, homeowners may reduce the thermostat setting or use a dehumidifier. However, in extremely humid climates, when outdoor temperatures are moderate, or in cases where the air conditioner is oversized, the air may not reach a low enough humidity to achieve a comfortable level. To learn how central air conditioners compare to other cooling systems, check out our Energy Saver 101 Infographic: Home Cooling.Īir conditioners dehumidify the air to improve comfort. This cooled air becomes warmer as it circulates through the home then it flows back to the central air conditioner through return ducts and registers.

Supply ducts and registers (i.e., openings in the walls, floors, or ceilings covered by grills) carry cooled air from the air conditioner to the home. Central air conditioners circulate cool air through a system of supply and return ducts.
