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, cooling it with a refrigerant, and then blowing the chilled air back into different rooms. This system is efficient for maintaining a comfortable temperature in larger spaces, making it popular in homes and offices. The main components of central air conditioning include the air conditioner, ductwork, and thermostat. The thermostat allows you to set your desired temperature, while the air conditioner cools the air. Regular maintenance, like changing filters, helps keep the system running smoothly.
