 Zoned heating and cooling is one of the hottest new concepts in efficient energy usage. With a zoned system, you can independently control the airflow sent to various rooms or zones in your home, directing heating or cooling where you want it at various times of the day.
To make this possible, a system needs a special multi-zone programmable thermostat and a few motorized dampers. For best results, the air handler’s output should be variable. In fact, it’s best if it can be controlled over an infinite range of speeds, automatically adjusting the amount of heating or cooling delivered throughout the house according to the need.
