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 homes that have areas that are rarely used, they can also be beneficial in situations where you and your family can’t agree on the temperature in certain portions of your home. There are a variety of additional benefits of zoning systems, including efficiency and comfort.
