Is a Heat Pump Worth It in South Carolina?

Last updated June 27, 2026 · based on South Carolina energy prices

In South Carolina, where residential electricity averages about 14¢/kWh and natural gas about $1.5/therm, switching from a gas furnace can save roughly $134/year on heating. South Carolina has a mild-to-moderate heating climate, which means a heat pump runs at a seasonal efficiency (COP) near 3.3 here.

SystemEstimated annual heating cost
Gas furnace (95% AFUE)$632
Heating oil$1,523
Heat pump$497

If you currently heat with oil, the picture is much stronger: a heat pump could save around $1,026/year versus heating oil at South Carolina prices. Against electric baseboard heat, a heat pump cuts heating energy use by about two-thirds, so the savings are even larger.

What this means for South Carolina homeowners in 2026

The federal heat pump tax credit expired December 31, 2025, so a 2026 install in South Carolina carries the full upfront cost unless you qualify for a state or utility rebate. Because South Carolina's climate is mild-to-moderate, the strongest financial case is when you're replacing both an old furnace and an aging air conditioner at once — the heat pump does both jobs with one system. With meaningful running-cost savings on top of combined heating and cooling, the payback math in South Carolina is favorable for most homes.

South Carolina rebates

Check whether South Carolina has launched its HEEHRA home-electrification rebate program (worth up to $8,000 for income-qualified households) and confirm it still has funding before counting on it — availability changes month to month. Also check your local electric utility, which may offer its own heat pump rebate of a few hundred to a couple thousand dollars. See our 2026 rebate guide for details.
