Questions people in South Carolina actually ask
How much is the heat pump rebate in South Carolina in 2026?
It depends on your utility. Duke Energy pays $350 to $900 for an efficient heat pump and $1,500 for replacing electric furnace or baseboard heat. Dominion Energy South Carolina pays $400 or $500 when a heat pump replaces a heat pump and $650 when it replaces an electric furnace. Santee Cooper pays $300 to $700. The federal tax credit ended with 2025.
Are the HOMES and HEAR rebates available in South Carolina?
No. The South Carolina Energy Office says they are not yet available and are expected to launch in 2026. HEAR will pay up to $14,000 below 150% of area median income, and HOMES $2,000 to $16,000 for whole-home projects.
Does Dominion Energy South Carolina pay to switch from gas to a heat pump?
No. Its heating and cooling rebates do not allow fuel switching: a heat pump must replace a heat pump, or an all-electric furnace for the $650 rebate. Its gas rebates likewise pay only when a gas furnace replaces a gas furnace.
Who qualifies for free weatherization in South Carolina?
Households at or below 200% of the federal poverty level, $66,000 a year for a family of four, or receiving SSI, apply through the community action agency for their county. Duke Energy also funds weatherization for its customers under 200% of poverty or on SNAP, WIC or LIHEAP.
Does South Carolina have a solar tax credit?
Yes. The state income tax credit is 25% of the cost of a solar system or a geothermal heat pump, limited to $3,500 a year and to 50% of that year’s state income tax, with the rest carried forward up to 10 years. It is claimed on Schedule TC-38.
Do South Carolina electric co-ops have rebates?
Some do, and four (Aiken, Black River, Santee and Tri-County) offer Help My House loans for heating and cooling, sealing and insulation, repaid on the electric bill at 5% over up to 10 years. Ask your co-op for its own offers.
