Central heating and cooling systems are designed to regulate indoor temperatures in homes and buildings. These systems typically use a central unit, such as a furnace or air conditioner, to distribute warm or cool air through a network of ducts. This ensures that every room receives a consistent temperature, enhancing comfort and energy efficiency. In addition to air distribution, central systems often include a thermostat, which allows users to set their desired temperature. Some systems also incorporate heat pumps or boilers for heating, while chillers may be used for cooling. Overall, these systems provide a convenient way to maintain a comfortable living environment year-round.
