Geothermal Systems

Through direct use of the geothermal energy provided by the Earth, Wallace Heating & Air takes advantage of a renewable source of power to heat and cool homes cleanly and efficiently. Heat is transferred from one place to another using geothermal heat pumps, allowing for a more economical climate control that saves homeowners money over conventional heating and cooling systems. It is estimated that switching to a geo-exchange system can save homeowners 30-70 percent on heating and 20-50 percent on the cost of cooling.

How Geothermal Heat Pumps Work

Geothermal heat pump systems transfer heat to or from the ground, allowing for the extraction of heat for winter warming and efficient cooling during warmer months.

At the center of a heat pump is a cycle of refrigerant that transfers the heat. Heat is exchanged with the ground to take advantage of warm, stable temperatures below the surface. This consistency allows for efficient performance even during the coldest months of the year.

Heat pumps can improve the normal flow of heat from warmer to cooler spaces, or move heat in the opposite direction, against natural flow, depending on what is needed.
