These York® units are compact and deliver cooling or heating to structures without installing air handlers and ductwork. The manufacturer considers them a perfect solution for homes without ductwork and for room additions or remodels. Many of the ductless units can be used in commercial applications, especially to condition computer-server rooms where temperatures must be maintained, even in winter, when other parts of the building are not being cooled.
