A geothermal heat pump and a traditional heat pump are different. A geothermal heat pump uses the earth's temperature for heating and cooling while a traditional heat pump uses the outside air or water. Geothermal heat pumps are more energy-efficient and eco-friendly. If you're looking for heat pump installation in Castle Rock, Colorado, contact Colorado Bear Heating & Air at (720) 402-4242.
