“Highly Recommend — Honest, Professional, and Great Value. Zero Homes recently replaced my old furnace and AC with a heat pump and high-efficiency gas furnace. I worked with Conner on the initial quote — he was incredibly honest, transparent, and took the time to walk me through multiple options, helping me understand the pros and cons of each. Their pricing was very competitive compared to other vendors.”
Dual-fuel heat pumps
Dual-fuel heat pump installation.
A dual-fuel system pairs a high-efficiency heat pump with your existing gas furnace, switching between them automatically based on outdoor temperature. The heat pump handles most of your annual heating — efficient in mild and cold weather. The gas furnace kicks in for the coldest stretches. Lower energy bills most of the year, gas reliability when you need it, no full-electrification commitment.

The Basics
What is a dual-fuel heat pump?
A dual-fuel system is a heat pump installed alongside your existing gas furnace, both controlled by one thermostat.
Below a switchover temperature (typically around 25–35°F), the thermostat hands off to the gas furnace. Above that, the more efficient heat pump runs.
One install, two heat sources — efficiency in mild weather, gas reliability in the coldest stretches.
Find Your Fit
Is a Dual Fuel Heat Pump Right for Your Home?
Dual fuel pairs an electric heat pump with a gas furnace, so the heat pump carries most of the season and the furnace steps in only on the coldest days. It's the middle path between keeping gas and going all-electric.
Best For
If any of these sound like your home, dual fuel is the right path.
- A gas furnace with years of life left that you'd rather keep than replace
- Existing ductwork for whole-house heating and cooling
- Cold-climate winters where you want a gas backup for the deepest cold
- Cutting gas use and energy bills without removing working equipment
- Phasing into electrification one step at a time
Not the Right Fit
If dual fuel isn't a fit, try these other options.
- Going fully electric and removing gas, a standard ducted heat pump does the whole job
- Homes without ductwork, a ductless mini-split is the better path
- No gas service, or a furnace already at end of life you'd rather not keep
