Geothermal Energy
Geothermal energy uses the earth’s stable underground temperature as a renewable source for heating and cooling. In HVAC applications, geothermal heat pumps move heat between the ground and a building, providing efficient heating in winter and cooling in summer. These systems can significantly reduce energy use and operating costs compared to conventional equipment.
