Ductless (aka Mini-Split) Air-Source Heat PumpsThis is a common, straightforward way to add a heat pump to a house or section of a house that doesn’t have ducts. Instead of relying on ductwork to move warm or cold air through a house, it connects to one or more individual indoor air handlers, or “heads,” which are installed throughout the home. The air-handler heads are usually placed high on a wall, but for homeowners who don’t like the look or don’t have the space, there are heads that can be placed inside the ceiling or floor. Mini-splits are also more energy-efficient than ducted heat pumps because they avoid the energy losses associated with ductwork. CR doesn’t have enough brand-specific data yet to report on the prices members paid to purchase and install ductless mini-splits. According to HomeAdvisor, the average cost to install one unit is $3,000, but the price could range from $2,000 to $6,000 depending on how it’s mounted and installed. For multiple mini-splits, plan to spend up to about $14,500, depending on home size, heat pump capacity, type of heat pump, and how many units you choose., Shopping for a heat pump or mini-split?
