Geothermal heat pump systems use the ground’s constant temperature to heat and cool a home. In our climate, the ground four feet below the surface is between 58 and 62 year-round, perfect for a geothermal heat pump system to deliver heating or cooling needs regardless of outdoor temperatures. Therefore, you can expect higher HSPF efficiency ratings (Heating Seasonal Performance Factor) from geothermal systems than some air-source systems.
