Why should I purchase a zoning system? A zoning system allows you to parcel your residence and heat or lower the temperature in each part differently. While these systems function well for homes that have parts that are infrequently occupied, they may also be helpful in situations where you and your family argue about the temperature in certain areas of your house. There are a number of additional pluses of zoning systems, including efficiency and comfort.
