A heat pump and a furnace, each on its best days.
Dual fuel pairs an electric heat pump with a gas furnace. The heat pump handles mild weather efficiently and the furnace takes over on the coldest nights.
- Equipment: Heat pump plus gas furnace
- Control: Smart switchover by outdoor temperature
What it is, and why it matters.
A dual fuel system uses a heat pump for cooling and for heating in mild weather, then switches to a gas furnace when it gets cold enough that the furnace is the better choice. In a climate like Middle Tennessee's, where most winter days are mild and a few are very cold, it can lower operating costs while keeping the house comfortable on the worst nights.
Nashville HVAC designs and installs dual fuel systems across Middle Tennessee. We size the heat pump and furnace together, set the switchover temperature with you and wire controls so the handoff is smooth. We also explain when a straight heat pump or a gas furnace with an air conditioner is the simpler choice.

Strong in a cold snap
The furnace takes over when the heat pump loses its advantage.
One system, tuned
