We installed a geothermal heating and cooling system, with two wells located in the rear of the property, to provide a consistently comfortable interior environment at very low operating cost. The low operating cost of the system would pay for its' construction cost within seven years, as this client has experienced a maximum heating or cooling expense of $115 per month in the most extreme of exterior temperatures, when compared to the large fluctuations in cost of a natural gas heating and electric cooling system.
