A hybrid system contains both a heat pump and a gas furnace.
During most of the year, when outdoor temperatures are relatively mild, the heat pump efficiently provides the home's heat.
At a certain point, when outdoor temperatures get very cold, the gas furnace becomes more efficient at heating than the heat pump. At this temperature, the thermostat senses the cold outdoor temperature and automatically switches on the gas furnace and switches off the heat pump, maximizing the efficiency of your heating system.
ECONOMICAL
Dual-Fuel Hybrid Heat Pumps
Electric Efficiency.
Gas Heat When You Need It.
Bring electric heat pump comfort and gas furnace heating together in one matched system. Your heat pump heats and cools your home, with a compatible gas furnace ready when additional heating is needed.
Serving Seattle homeowners with guidance on equipment, existing ducts and furnace compatibility.
One coordinated system
Two ways to heat. One way to stay comfortable.
Heat pump heating
An electric heat pump moves heat into your home through your ductwork.
Gas when needed
System controls can switch to your compatible gas furnace based on the equipment and settings selected for your home.
Summer air conditioning
In warmer weather, the heat pump reverses operation to cool your home.
Explore your options
Dual-fuel choices from two trusted brands.
We start with your home, your comfort goals and the condition of your existing equipment.
Mitsubishi Electric intelli-HEAT
Connect a Mitsubishi Electric heat pump and intelli-HEAT coil to a compatible gas furnace for ducted heating and cooling.
- Electric heating and summer cooling through existing ducts
- Controls coordinate heat pump and gas furnace operation
- Existing furnace and ductwork assessed before installation
Compatibility must be confirmed. intelli-HEAT is designed for integration with furnaces certified to ANSI Z21.47/CSA 2.3 requirements.
Trane Dual-Fuel
Pair a Trane heat pump with a compatible gas furnace and controls for coordinated comfort throughout the year.
- Heat pump heating and air conditioning in one outdoor system
- Automatic changeover with a properly matched system and controls
- Equipment selected to fit your home and heating needs
The furnace, heat pump and controls must be properly matched. Changeover settings depend on the selected system and installation.
Good questions to start with
Is dual-fuel right for your home?
Can I keep my existing gas furnace?
Possibly. We need to check its condition, certification, capacity and compatibility with the proposed heat pump, coil and controls. We also assess your ductwork before recommending a system.
When does the system switch to gas heat?
It depends on the equipment, controls and settings chosen for your home. A properly configured system coordinates changeover automatically; there is no single switch temperature that applies to every installation.
How is dual-fuel different from an all-electric heat pump?
A dual-fuel system uses an electric heat pump plus a gas furnace for heating. An all-electric system uses electric heating equipment without a gas furnace. Both can provide air conditioning; the right choice depends on your home, equipment and goals.

Benefits of a Dual-Fuel Hybrid Heat Pump System
- Dual fuel system ensures your home is heated as efficiently as possible, no matter how cold it is outside
- The system automatically switches to gas heating when it gets below a certain temperature outside
- When a 2-stage or variable speed heat pump is combined with a variable speed furnace, the system is able to run at lower speeds with quieter, more efficient operation, more even temperatures, and better air filtration
- During milder cold weather, the air heated by the heat pump is less dry than a gas furnace puts out, making the air more comfortable in your home
- During the coldest days of the year, the gas furnace handles the heating and puts out higher temperature air, improving your comfort
- A dual-fuel hybrid heat pump system is excellent for homes with existing gas furnaces, allowing the home to retain its gas appliances while having one of the world's most efficient heating systems
- Provides air conditioning in the Summer, just like a traditional heat pump
