What Is a Dual Fuel HVAC System?

San Francisco winters are milder than cities in Northern states, which is why San Franciscans have little use for high-capacity heating and air conditioning systems. Instead, most opt to use heat pumps, which offer better energy efficiency for homes in milder climates. Heat pumps don’t consume as much energy or fuel as, say, a furnace. This means they also don’t produce the same amount of heat, making them perfect for a San Franciscan winter.

However, every now and then, there are days that get a little too cold or a little too hot for a heat pump to handle. These days don’t occur often enough to justify switching to a full furnace, however. The solution? A dual fuel system. Let our experts at Schmitt explain what dual fuel HVAC systems are and the benefits they can provide your home.

What Is a Dual Fuel HVAC System?

Dual fuel systems are hybrid systems that, quite literally, combine a heat pump and a furnace. They need to be installed by a professional heating system repair and replacement technician, as they’re a little more complex than conventional heating systems. During the day, the heat pump is the primary source of heating and cooling, but when temperatures dip below a certain threshold–usually 35 or 40 degrees–the furnace takes over and provides adequate heating.

Pros of Using a Dual Fuel HVAC System

Hybrid systems are often designed so that the benefits of one system balance the drawbacks of the other. In this case, you’re getting the energy efficiency, and therefore savings, provided by a heat pump while still keeping your home warm and toasty with a furnace on certain days.

Cons of Dual Fuel HVAC Systems

Because duel fuel systems are a two-system combo, heating and air conditioning repair costs can be a little higher. The installation of hybrid systems also costs more upfront than other more conventional HVAC systems.
