Many homes use one thermostat to regulate temperatures for the entire house, despite the fact that different parts of the house have different climate-control needs. For families that want greater control over the heating and cooling levels in their home, however, a zoning system makes a great option. Rather than struggling to maintain one temperature for the whole house, zoning divides the home into more than one section, each with its own separate temperature control. Each zone might be a single room or multiple rooms.
