Keep in mind that a heat pump can provide both heat in winter and AC in summer.

Compare your total cost of installation and operation to an Air Source heat pump. The compressor of an air source heat pump makes significant noise outside (similar to the compressor of a whole house air conditioner). The compressor of a ground source heat pump makes some noise inside, the pumps also make a bit of noise, and there can be some condensation on the pumps in the summer.

You will need to have a well insulated and tight house. If the house is tight, you will also want heat recovering ventilation.

My guess is that Air Source makes sense for typical single family houses and that Ground Source makes sense for large commercial and government buildings.
