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.
Heat pumps usually cost anywhere from $3,000 to $10,000, including installation. The average price is usually closer to $6,000 or $7,000. Geothermal heat pumps are the one exception. Because they are far more efficient, saving a significant amount of money on energy bills, they sell for as much as $10,000 to $25,000.
