Heat pump vs Furnace in Sumner County, Tennessee
When a heat pump makes sense
If your home already heats with electricity, a heat pump is the natural choice, since you are not walking away from a cheaper gas rate to get one. Winter nights here average 30°F, cold enough that a standard heat pump will struggle on the coldest nights, so look at a cold-climate model built to keep its heating power down there. It also covers your cooling, which a furnace never will.
When a furnace makes sense
If gas line is already run to your home, a furnace is worth a hard look, since gas runs at least 20% cheaper than a heat pump at Tennessee prices. You will still need a separate system for cooling, but for a home that heats 7 months a year, that running cost difference adds up. It is the right call for anyone who wants the lower bill and does not mind pairing it with a separate air conditioner.

Heat pump wins in Sumner County.
Most homes here already run on electric heat, and at 30°F on a winter night a heat pump still keeps up without needing gas run to the house.
If your home already has a gas line and you would rather keep heating and cooling as two separate costs, a furnace paired with a separate AC still makes sense.
