If you want a better way to heat and cool your home, consider a geothermal HVAC in Oklahoma City, OK. A geothermal heat pump uses ground temperatures to exchange heat rather than ambient air. This is the main difference between a geothermal heat pump and a standard heat pump, which uses outside air temperature. In Oklahoma, the temperature of outside air varies widely daily and between seasons. Conversely, the ground temperature six to eight feet down is very stable. It is warmer in winter and cooler in summer than the outside air temperature. Conditions vary, so it is best to use a professional geothermal company to evaluate the geothermal potential in your area. Geothermal heat pumps use less energy than standard units and can pay for themselves in a few years.
