Dual-Fuel means using two fuels to heat instead of one. In most cases, this means combining a high-efficient electric heat pump with a fossil fuel furnace (natural gas, propane or oil). A heat pump is a unit that will heat your space in the winter and cool it efficiently in the summer.

During mild winter temperatures, 80% of our winters are mild, the heat pump operates at an incredible 200 to 300% efficiency. During the coldest times, the fossil fuel furnace burns at its greatest efficiency.

By using these two sources of heat, you can heat for less. An outdoor sensing thermostat will activate which ever unit will heat most efficiently.

A heat pump has the ability, through reverse refrigeration, to provide both heating and cooling with one unit. In the summer a heat pump will extract heat and discharge it to the outside, leaving the inside air cooler. In the winter, by reversing the flow of the refrigerant, the unit extracts heat from the outside air and brings it inside where it’s distributed through the duct work.

In commercial applications the heat pump can be either a package unit or a split unit. A packaged unit contains both coils and can be set on the roof or the ground and air passes through the ceiling or the wall and connects to the duct distribution system. While a split system has the heat pump with the condenser coil outside and the a-coil is inside the building in the air handler which is connected to the ductwork.

Heat pumps are an efficient means to both heat and cool. Heat pumps can be connected to a fossil fuel furnace or an electric heat strip which is included in the air handler to provide additional heating.

High efficiencies, up to 18 SEER, are available from multiple manufacturers. Some systems require changing the furnace and coil in order to reach desired energy rating. Two-stage, variable-speed compressors are available on 16 SEER or higher.

Gas furnaces are now available in up to 98% with two stage gas valves. There are a vast array of choices for most gas furnaces. Any 80% AFUE units require a flue liner to be installed in all existing flues. 90+ units require two PVC pipes, one for exhaust and one for fresh air. We do a combustion analyzation on gas furnace installations and service to ensure safe and proper operation of your furnace.

Boilers are pressure vessels designed to heat water or produce steam, which can then be used to provide space heating and/or service water heating to a building. In most commercial building heating applications, the heating source in the boiler is either natural or propane gas fired burner. Oil fired burners and electric resistance heaters can be used as well. High efficient 90+ and standard 80+ AFUE are available for all types of hot water or steam heating.
