Zone control heating, or air conditioning for that matter, is one of the most efficient ways to condition a home. The reason we say this is because with zoning, each room can have its own temperature, meaning each family member in your household can heat or cool their space to their specific preference.
If you’re purchasing a central furnace for the first time, then a great option is to have dampers installed in the ductwork upon its installation to achieve this zone control heating. But what if you already have a furnace in place? Can you still have zone controlled heating? Your ducts can be retrofitted, but it is a complicated process and is better performed during installation. That doesn’t mean you’re out of luck! You may just want to consider a different type of heating system that can also serve as an air conditioner—the ductless system.
