Ductless systems, Regardless of their title, more info do use a little level of ductwork. Rather then sending conditioned air in the ducts guiding your partitions, each air handler in a ductless system is linked on to an outdoor compressor device by means of only one modest duct, delivering greater control around temperature zones but necessitating much more units to function. A ductless mini-split is an efficient illustration of a “duct-absolutely free” system.
