This will depend on your needs and the space you are heating and
cooling. If you have a small home or business or open space you are probably
fine with a ducted system, they are generally powerful and more economical to
have installed. Larger spaces with many rooms or zones that need to be kept at
varying temperatures would do better with a ductless system. A ductless
mini-split system can be installed if you have a space separated from the rest
of the building, such as a basement that isn’t accessible to your ductwork.
