Not sure if you have a dual fuel heating and cooling system? Most homes feature either a gas-powered or heat-pump system with an electric heating backup. However, some homeowners enjoy the best of both worlds, employing the benefits of dual-fuel systems.
Dual fuel systems deliver superior performance and efficiency by combing the best of gas furnace and heat pump technology. In dual fuel systems, both components share ductwork to distribute heated and cooled air throughout your home. In the summer and mild spring and fall weather, the heat pump provides the most efficient and least costly means of home comfort. In ideal conditions, heat pumps can transfer 300% more energy than they consume. In the coldest winter months (below 35-degrees), when heat pump systems are less efficient, the heat pump shuts off and the furnace takes over, delivering 90% efficiency on average.
The easiest way to determine if you have a dual fuel system is to ask your local heating system repair company. However, it may be possible to determine this without a service call. The first place to look for this information is on the metal box inside or outside your home that controls your HVAC system. The model number on the faceplate of this unit, typed into a quick Google search, can help you uncover your system type. In addition to checking this panel, identifying key components of your HVAC system can help you determine what type of heating and cooling you have in your home.
Setting your thermostat to engage heating and cooling, respectively, can help you identify your system. Here’s what to look for:
