Geothermal systems are the most energy efficient heating and cooling systems available today, with efficiencies of 300% to 400%. No other heating and cooling systems can match the energy efficiency and environmental benefits of geothermal systems.
An even comfort level is created because the warm air is moved in slightly higher volumes and saturates the building with warmth more evenly. This helps even out hot or colds spots and eliminates the cold air blasts common with fossil fuel furnaces.
