Why should I buy a zoning system? A zoning system enables you to divide your home and heat or cool each space differently. While these systems work well for houses that have parts that are rarely used, they can also be helpful in situations where you and your family disagree on the temperature in various areas of your home. There are a collection of additional pluses of zoning systems, including efficiency and comfort.
