Residential air conditioning is a system designed to cool and dehumidify the air in homes. It works by circulating refrigerant through coils, absorbing heat from the indoor air and releasing it outside. This process helps maintain a comfortable temperature, especially during hot weather. There are various types of residential air conditioning systems, including central air conditioning, window units, and ductless mini-splits. Central systems use ducts to distribute cool air throughout the home, while window units are installed in individual rooms. Ductless mini-splits offer flexibility and efficiency, allowing homeowners to control temperatures in specific areas.
