Heat pump vs Furnace in Wilson County, Tennessee
When a heat pump makes sense
If your home already heats with electricity, a heat pump is the natural fit, since it also gives you cooling in the summer from the same system. Winter nights here average 31°F, cold enough that a standard heat pump will lose some capacity, so look for a cold-climate model built to keep its output at that temperature. It costs more to run than gas, but you are only heating about 7 months of the year.
When a furnace makes sense
If your home is already set up for natural gas, a furnace is worth keeping, since gas heat runs at least 20% cheaper here than a heat pump at Tennessee prices. It has no trouble holding its output when nights drop to 31°F and below. The tradeoff is that a furnace only heats, so you would still need a separate system for cooling.

Heat pump wins in Wilson County.
Most homes here already run on electricity and were built recently enough to pair well with a heat pump, so that's the easier install.
If your home already has a gas line and you want the lowest heating bill, a furnace still costs less to run than a heat pump at Tennessee's electric rates.
