Air Heat Pump Cost

• It runs about $500 -$1,500 to install a self-contained through-the-wall or window unit air-source heat pump in a single room (no ductwork is required). More expensive units have a greater heating and cooling capacity, and this price range may include installation. Lower prices are do-it-yourself installation, particularly for window units (which are relatively easy to install).
• Expect to pay about $2,000 -$5,000 for a split system (one piece of equipment is located outdoors, another indoors) electric heat pump for an average home (3 ton capacity). Higher-priced models have options such as a two-stage compressor for more power when additional heat is needed, or include a hot water heater as part of the system. These systems require the same type of ductwork as central heat and air, and adding ductwork is often cost-prohibitive.
• For home without ductwork, professional installation of a ductless mini-split electric air-source heat pump system (an outdoor compressor and mounting one or more indoor units) for an average home (3 ton capacity) runs about $4,500 -$6,000 or more, depending on the number of indoor units or zones installed.

• Air-source heat pumps work best in climates where temperatures rarely drop below freezing. Through-the-wall or window units are usually a single self-contained unit, but can only heat or cool a single room. For a standard single-family home, a typical split-system air-source heat pump system has two parts, an indoor unit with a coil (providing electric resistance heat) and a blower that pushes warm or cool air through the house, and an outdoor unit with another coil, fan and a compressor or pump. There are also "packaged" air-source systems that combine the standard indoor and outdoor units into a single outdoor cabinet which is typically installed on the roof. The US Department of Energy provides a detailed overview.
• Similar to ductless air conditioning, a ductless mini-split heat pump system consists of an outdoor compressor or condenser and multiple indoor air-handling units. The indoor units are linked to the outdoor unit by a conduit system. Mini-split heat pumps are flexible in terms of creating a number of heating-cooling zones within a home, each with its own thermostat. The indoor units can be mounted in the floor, wall or ceiling. They are usually less intrusive than window air conditioners but don't necessarily have the built-in look of ducted central systems. The US Department of Energy lists the advantages and disadvantages of mini-split heat pumps.

• In an older home, adding an electric heat pump might require hiring an electrician to upgrade the electrical panel to 200 amps, which can cost an additional $1,300 -$3,000.

• Utility companies and other agencies may offer rebates when you purchase an energy-efficient air source heat pump; check with your local power company or search for rebates listed at EnergyStar.gov.
• Some energy-efficient heat pumps may qualify for a federal tax credit.

• Major manufacturers include Armstrong Air, Bryant, Carrier, Lennox and Trane. The Department of Energy explains the advanced features to look for that will improve a heat pump's performance.
• The Cornhusker Public Power District provides a checklist for hiring a heat pump contractor. Contractor referrals are available from the North American Excellence certification program and the Air Conditioning Contractors of America -- and your local power company may have a list of contractors in your area.
• Get several estimates, making clear what is (and isn't) include in each quote. Request and check references; ask about the contractor's length and type of experience; and be sure the company is properly bonded, insured and licensed in your state. Check whether there are any complaints with the Better Business Bureau.
