The main advantage of ground-source, or geothermal, heat pumps compared to air-source systems is that they have a more stable temperature source. Ground-source heat pumps utilize the relatively constant temperature of the earth to exchange heat. Below a certain depth, the ground temperature remains consistent throughout the year, which allows these systems to operate more efficiently across different seasons. This stability means that geothermal systems can maintain a higher efficiency rate in both heating and cooling modes, as they do not rely on the fluctuating temperatures of the air, which can vary greatly depending on weather conditions.

This stable thermal source contributes to a more reliable performance and energy efficiency of ground-source systems, making them a preferred choice for many applications despite their often higher initial installation costs. Other factors such as maintenance and portability are not significant advantages of geothermal systems over air-source systems, and installation costs may not favor geothermal systems in every case.
