Package Dual Fuel

An HVAC dual fuel package system is a type of heating, ventilation, and air conditioning (HVAC) system that combines two different types of fuel sources for optimal energy efficiency. Typically, this system uses both electricity and natural gas or propane. It is designed to provide both heating and cooling while switching between the two fuel sources depending on the outdoor temperature.

The dual fuel system includes a heat pump, which is a compressor used for heating and cooling, and a gas furnace, which provides additional heating during colder temperatures. The heat pump is ideal for moderate climates, as it can efficiently heat and cool a home by transferring heat from the outside air into the home during the winter, and vice versa during the summer. However, when outdoor temperatures drop too low, the heat pump becomes less efficient, and the gas furnace kicks in to provide supplementary heating. Dual fuel package units are like package heat pumps but instead of using electric heat strips for supplemental heating they use a built-in gas furnace instead. Dual fuel heat pumps are ideal for locations where gas heating is more affordable than electricity.

This system is controlled by a thermostat that automatically switches between the heat pump and the gas furnace based on the outdoor temperature. When the temperature is mild, the heat pump operates alone, consuming less energy. But when it gets colder, the system switches to the gas furnace for more effective heating, saving energy and costs. The dual fuel package system offers homeowners the flexibility to enjoy both energy-efficient heating and cooling while maintaining comfort throughout the year.
