    A Deeper Understanding of Geothermal Heat Pumps

    All heat pumps are exceptionally efficient and excellent for the environment, however, thanks to their unique technology, geothermal heat pumps are considered the most eco-friendly HVAC system on the market. Unlike most heat pumps that rely on air to heat and cool, geothermal heat pumps harness the constant temperature of the Earth's crust. By tapping into the Earth’s heat, these systems efficiently warm buildings before returning the excess heat back to nature during its cooling cycles.
