Why should I buy a zoning system? A zoning system allows you to parcel your house and heat or lower the temperature in each part differently. While these systems operate well for buildings that have parts that are infrequently occupied, they could also be great in situations where you and your family can’t agree on the temperature in different areas of your home. There are a number of additional bonuses of zoning systems, including efficiency and comfort.
