Central air conditioning is a cooling system that uses a network of ducts to distribute cool air throughout a building. It works by pulling warm air from inside the home, cooling it with a refrigerant, and then blowing the chilled air back into various rooms. This system is efficient for maintaining a consistent temperature and comfort level in larger spaces. The main components of central air conditioning include the compressor, evaporator coil, and air handler. The thermostat controls the temperature settings, allowing homeowners to adjust the cooling as needed. Central air conditioning is popular in many homes because it provides effective cooling and can also improve indoor air quality.
