Heat Pumps and Dual Fuel systems

A heat pump system is a great investment that can help reduce utility costs throughout the year. A heat pump will provide you with energy efficient heating and cooling, nearly year-round. On extreme winter days, when it is too cold for the heat pump to operate efficiently, your furnace will automatically provide you with warm, reliable heat. A heat pump can be combined with an electric furnace (most common) or a gas furnace (Dual Fuel). A Dual Fuel system is a particularly good investment for a homeowner that is looking to reduce the cost of their high gas bills. Rather than installing a high-efficiency gas furnace, a Dual Fuel system can be installed at comparable cost and provide you with lower utility bills, all while reusing your existing gas flue.
