What Is a Dual-Fuel Heat Pump and Is It Right for Kentucky?
How dual-fuel systems combine a heat pump with a gas furnace for maximum efficiency and comfort in Central Kentucky winters.

A dual-fuel heat pump pairs an electric heat pump with a gas furnace backup, automatically switching between the two based on outdoor temperature. It is one of the most efficient heating configurations for Central Kentucky because it uses electricity when mild and gas when bitter cold.
How does dual-fuel work?
The heat pump provides heating and cooling for most of the year. When outdoor temperatures drop below 30–35°F, the system switches to the gas furnace. During Kentucky's shoulder seasons, the heat pump runs almost exclusively and costs significantly less than gas heating.
Why is dual-fuel a good fit for Kentucky?
Kentucky winters are variable — many days above 35°F with periodic dips into the teens. That pattern is ideal for dual-fuel.
- Lower operating costs than gas-only for most of the season
- Reliable gas backup for the coldest nights
- The heat pump also provides summer cooling
- Federal tax credits up to $2,000 for qualifying equipment

Frequently Asked Questions
- What is a dual-fuel heat pump system?
- A dual-fuel system pairs an electric heat pump with a gas furnace. The heat pump handles heating in mild weather, and the furnace takes over when temperatures drop below 30-35°F.
- Is a dual-fuel system worth it in Kentucky?
- Dual-fuel is one of the best heating configurations for Kentucky because it uses the most efficient heat source at every temperature — electricity most of the season and gas during the coldest days.
- Can I add a heat pump to my existing furnace?
- In many cases, yes. If the existing furnace is in good condition, a heat pump can be paired with it without replacing the furnace.
