Carrabassett Valley, Sugarloaf USA. Three Fujitsu RLS3 Ductless Mini Split Heat Pump units installed by Central Maine Heat Pumps in this home on the mountain. Lines in the entry were hidden in the wall and under the entry. Most of the lines for the living room unit were hidden in the basement and closet. The master bedroom lines were hidden outside in brown ducting. Because the living room and bedroom units were on a bedroom wall they were put on ground stands to avoid vibration noise in the wall.
