Heat pump vs Furnace in Johnston County, North Carolina
When a heat pump makes sense
If your home only has electric service and no gas line, a heat pump is the straightforward choice, and it costs about 5% less to run here than gas does. Winter nights average 33°F in Johnston County, mild enough that a heat pump keeps up most of the season. If you're replacing the system anyway, look at a cold-climate model, since standard heat pumps lose heating power once temperatures drop and cold-climate versions are built to hold it.
When a furnace makes sense
If your home already has a gas line and you'd rather keep a separate system for cooling, a furnace is worth considering. It only heats, so you would still need a separate air conditioner, and only 12% of homes in the county heat this way now. It suits a household that prefers gas heat specifically, or already has the ductwork and gas piping in place from a previous furnace.

If your home already has a gas line and you'd rather not rely on electricity to stay warm on the coldest nights, a furnace is still worth choosing.
