Geothermal heat pumps utilize the Earth’s constant temperature below the surface to provide both heating and cooling. The installation cost varies based on system size and loop type. On average, it ranges from $15,000 to $35,000. The cost per ton installed is approximately $4,000 to $8,000. When it comes to installation, it’s essential to consider a few factors. First, the installation process typically involves drilling boreholes or trenches for the ground loop system. The depth and length of these boreholes or trenches depend on the specific site conditions and the size of the system. Additionally, professional installation is crucial to ensure proper system performance and efficiency.
