Dual Fuel vs All Electric – Guide to Purchasing a Heat Pump

If you’re in the market for a new heating and cooling system, there’s a good chance you’ve come across heat pumps—versatile, energy-efficient systems that both heat and cool your home. But before you make the switch, one important decision remains:
Should you choose a dual fuel system or go all-electric?

This guide will help you understand the differences, benefits, and best applications of each setup—so you can make a confident, well-informed decision.

What Is a Heat Pump?

A heat pump is an all-in-one heating and cooling system that moves heat rather than generating it. In the summer, it works like an air conditioner—pulling heat out of your home. In the winter, it works in reverse—extracting heat from outdoor air and bringing it inside.

What’s the Difference Between Dual Fuel and All-Electric?

Both systems rely on a heat pump, but the backup heat source is what sets them apart:

• All-Electric Heat Pump System: Uses electric resistance heat as a backup when temperatures drop too low for the heat pump to work efficiently.

• Dual Fuel System: Combines an electric heat pump with a gas furnace that kicks in when outdoor temps fall below a set threshold.
