Zoned heating and cooling systems allow you to control the temperature of each room individually. By using a series of motorized dampers and thermostats that work independently, zoning can eliminate hot or cold rooms found in almost every home, while cutting energy by up to 25 percent. Warm air rises while cold air sinks, leaving upstairs rooms six to ten degrees warmer than ground level rooms. A single thermostat keeps the temperature balanced in the room where it is located, but can’t tell if the temperature has changed in other rooms of the house. Zoning helps maintain a consistent temperature throughout the house by providing different levels of air distribution to different areas of the home.
Zone controlled systems divide a home into areas with common heating and cooling needs during specific parts of the day. Air flow is controlled in each area by a separate thermostat. Instead of sending the same amount of heated or cooled air into all rooms every time the furnace or air conditioner is turned on, the system sends conditioned air only to the zones that need it.
