Heat pump vs Furnace in Berkeley County, South Carolina
When a heat pump makes sense
If you already heat with electricity, a heat pump is the easier fit, and it will also cool your home in summer instead of sitting idle half the year. Winter nights here average 38°F, mild enough that a standard heat pump can keep up without needing the cold-climate version built for harder winters. It runs about 5% cheaper than gas at South Carolina prices, and with heat only needed about 5 months a year, that savings comes on top of a season that is already short.
When a furnace makes sense
A furnace fits a home already set up to heat with gas, which is the case for about 19% of homes here. It only heats, so you would still need a separate way to cool the house in summer. It is a steadier choice on the coldest nights, when a standard heat pump has to work hardest to keep up.

Heat pump wins in Berkeley County.
Winters here stay mild, only about 38°F on average, so a heat pump keeps up fine and most homes already run on electric heat anyway.
If your home already has a gas line and you would rather keep heating and cooling on separate systems, a furnace is still worth considering.
