Benefits of a dual-fuel system
Why homeowners are choosing dual fuel:
Save money on your utility bills
A dual fuel system pairs a high-efficiency gas furnace with a heat pump coil in one integrated setup. The heat pump handles efficient heating and cooling most of the year, while the furnace provides powerful heat when outdoor temperatures drop.
Take advantage of Mass Save rebates
Because dual fuel includes a qualifying heat pump, Massachusetts homeowners can access valuable rebates and 0% financing options — while still keeping gas as part of the system.
Get year-round comfort
You get high-efficiency air conditioning in the summer, electric heat during milder weather, and dependable gas heat during colder stretches — all controlled through one thermostat.
Lower your climate impact
Dual fuel lets you electrify most of your heating without going fully electric. It’s a practical way to lower fossil fuel use while maintaining flexibility.

Frequently asked questions. And answers.
A dual-fuel system combines a high-efficiency electric heat pump with a traditional heating system, such as a gas or oil furnace. The heat pump handles heating and cooling during milder weather, while the furnace automatically takes over during very cold temperatures when it may be more efficient.
This setup allows your home to stay comfortable year-round while reducing energy use.
A dual-fuel system automatically switches between two heat sources depending on the outdoor temperature.
- Above a certain set temperature: the heat pump runs
- Below that set temperature: the furnace turns on
A smart thermostat manages this switch automatically, so you don’t have to think about it.
Dual-fuel systems are popular for homeowners who want to:
- Lower their heating costs
- Reduce fossil fuel use
- Keep their existing furnace as backup
- Add efficient air conditioning with a heat pump
- Transition gradually to electric heating
Yes, but usually much less than before.
The heat pump handles heating for much of the season, especially during fall, spring, and milder winter days. The furnace typically runs only during the coldest periods. Many homeowners see a significant reduction in fossil fuel consumption.
The switch point (often called the balance point) varies by home, but it typically falls between 5°F and 30°F.
Above this temperature, the heat pump heats the home efficiently. Below it, the backup heating system may take over. The switch point can be adjusted on your thermostat.
Yes. Dual-fuel systems are designed to operate efficiently even when temperatures drop below 0°F.
Yes. The heat pump provides air conditioning in the summer, replacing traditional central AC systems. This makes it a two-in-one heating and cooling solution.
Yes. In many cases, dual-fuel heat pump systems qualify for Mass Save partial-home heat pump rebates.
A partial-home rebate is designed for homeowners who install heat pumps but keep their existing heating system (such as a gas furnace, oil boiler, or propane system) as backup heat.
A dual-fuel system can be a great option if:
- Your furnace still has useful life
- You want to reduce fuel usage
- You want efficient cooling and heating
- You’re not ready to fully electrify your home
