Air Source Heat Pump (ASHP)
Air-to-air heat pumps cost less to install than geothermal heat pumps, but they can cost more to run because air temperature varies widely, whereas ground temperature remains relatively constant. Air-to-air heat pumps cost around $1,000, compared with $3,000 for geothermal heat pumps.
Costs vary greatly by region (and even by zip code). To get free estimates from local contractors, please indicate yours.
