Ductless systems vs. central HVAC The term Ductless Systems means these comfort systems do not utilize duct to deliver/distribute conditioned air. For perfect climate control one needs a unit in every room. Ductless systems allow to achieve unmatched energy savings, and as mentioned before – perfect temperature control. A central system that uses ducts has so many cons, that having a “machine” on a wall is not so bad. Now about a typical central system: Ductwork collects dust and dust mites, then “spills” the same in the air we breathe. It is costly to clean the ductwork, and it will… read more
