A heat pump will replace both the furnace and air conditioner/central air unit. It may be costly to install, with the national average falling between $3,956 and $6,702, but it will save you considerable money in energy costs.
1 Lower prices are do-it-yourself installation, particularly for window units, which are relatively easy to install. 2  It typically costs about $2,000-$8,000 to install a whole-house electric heat pump system in an average home (three-ton capacity) with existing usable ductwork. Expect to pay $500-$2,000 to install a self-contained through-the-wall or window unit air-source heat pump in a single room (no ductwork is required).
