As with any heat pump, geothermal heat pumps are able to heat, cool, and, if so equipped, supply the house with hot water. Some models of geothermal systems are available with two-speed compressors and variable fans for more comfort and energy savings. Relative to ASHPs, they are quieter, last longer, need little maintenance, and do not depend on the temperature of the outside air.

Geothermal heat pump systems have an average 20+ year life expectancy for the heat pump itself and 25 to 50 years for the underground infrastructure. Additionally, they move between three and five times the energy they consume    between a building’s interior space and the ground.
