Heat pump vs Furnace in York County, South Carolina
When a heat pump makes sense
If you already have central air, or you're picking one system to cover both heating and cooling, a heat pump makes sense here. Winter nights average 33°F, which is mild enough that a heat pump keeps up without a lot of strain, and it costs about 5% less to run than gas at South Carolina prices. Choose a cold-climate model if you want the extra margin on the coldest nights, since standard models lose some heating power as it gets colder.
When a furnace makes sense
A furnace fits if you want heat that never has to work harder as the temperature drops, since it burns gas rather than pulling heat from the outside air. It's worth a look if your home already has gas line service, since that's most of what a furnace needs beyond the unit itself. Keep in mind a furnace only heats, so you'd still need separate equipment for summer.

Heat pump wins in York County.
Winter nights only dip to 33°F here, mild enough for a heat pump to keep up, and it cools your home too come summer.
If your home already has a gas line and you are not planning to add air conditioning, a furnace paired with a separate AC unit can still make sense.
