What s comfortable in the bedroom, for example, when you re sleeping under the covers, might be chilly for the family room or the kitchen. It s called zoning. Zoning simply means equipping your home s heating and cooling system to operate the same way as your lighting one room, or one large area, at a time. Each zone is controlled by its own thermostat and dampers in the ducts. The best time to add zoning controls is during new construction, before a large portion of your ducting is covered by fresh sheetrock and paint.
Most existing homes are candidates for zoning as well.
Homeowners who install zoning see prompt payback.
