Why should I buy a zoning system? A zoning system enables you to divide your home and heat or air condition each space differently. While these systems work well for houses that have areas that are seldom visited, they can also be helpful in situations where you and your family argue about the temperature in various portions of your home. There are a variety of additional pluses of zoning systems, such as efficiency and comfort.
