Key takeaways
- Modern heat pumps heat efficiently in Middle Tennessee winters and also cool in summer.
- Gas furnaces deliver strong heat on the coldest days and can have lower fuel costs where gas is available.
- Dual-fuel systems combine a heat pump with a gas furnace and switch automatically.
- The best choice depends on fuel prices, your ducts, the home and your goals.
How they work
A heat pump moves heat from outside to inside in winter and reverses in summer to act as an air conditioner. Because it moves heat instead of making it, it can deliver more heat energy than the electricity it uses. A gas furnace burns natural gas to make heat and a blower sends it through ducts.
Both can be paired with the same duct system, and both can be installed with variable-speed technology for better comfort.
How they behave in our climate
Middle Tennessee winters are mild compared with the north, with plenty of days above freezing and a few hard cold snaps. That is an excellent fit for modern heat pumps, which work efficiently in these conditions and use backup heat only on the coldest nights.
Gas furnaces shine in those cold snaps and where natural gas is cheap and available. Many homeowners choose based on existing gas service and utility prices.
Why dual-fuel is popular
A dual-fuel system uses the heat pump most of the time and switches to the gas furnace when it gets very cold, which is when the furnace is the better value. It costs more up front but can offer the best mix of low bills and strong heat.

Quick answers
Do heat pumps work when it is freezing?
Yes. Modern cold-weather heat pumps keep heating below freezing, and a backup heat source covers extreme cold.
Is a heat pump cheaper to run than a furnace?
Often, depending on electricity and gas prices. In many Middle Tennessee homes a heat pump is cheaper to run for most of the winter.
