Ductless wall-mounted heat pumps and air-conditioners, commonly known as “mini split” heat pumps, do not need air ducts like central systems. The outdoor unit (condenser) and the indoor unit (evaporator) are connected by refrigerant piping and electrical wires that pass through a small 3″ opening in the wall.
Ductless wall-mounted heat pumps offer several advantages:
- Can be controlled individually and adapted to each room where they are located, thereby optimizing comfort while reducing energy consumption.
- Perfect for retrofits where it’s impossible or very expensive to install air ducts in existing ceilings and walls.
