Older homes built with hydronic oil baseboards or radiators often lack the ductwork necessary for standard central air. For these residences, forced-air retrofits can seem daunting.
K2 specializes in whisper-quiet, multi-zone ductless mini-split heat pumps and slim-duct compact systems. These advanced inverter units allow you to establish independent climate zones in individual bedrooms, living rooms, and finished basements without altering historic walls or sacrificing closet space.
