Heat pump vs Furnace in Spartanburg County, South Carolina
When a heat pump makes sense
If you're on electric heat now, or building new, a heat pump fits. Winter nights here average 33°F, mild enough that a heat pump keeps up without much strain, and it costs about 5% less to run than gas at South Carolina prices. It cools your house in summer too, so one system does both jobs. Just make sure the model installed is rated for cold climates, since standard models lose heating power once temperatures drop.
When a furnace makes sense
If your house already has a gas line run to it, a furnace is worth keeping. It heats on natural gas and won't lose output on the coldest nights of the year, though those are rare here. You'll need a separate system for cooling, since a furnace only heats. With heat needed only about 7 months a year, the case for switching away from gas mostly comes down to what you're already set up to use.
