South Carolina Heat Pump Rebates
Stackable incentives available to South Carolina homeowners installing a qualifying heat pump in 2026.
What's available in South Carolina
South Carolina has a robust set of utility-funded heat pump rebates across its two large investor-owned utilities (Duke Energy Carolinas/Progress and Dominion Energy SC), the state-owned Santee Cooper, and several electric cooperatives (Berkeley, Palmetto, Blue Ridge). Typical air-source heat pump rebates run $400–$1,000, heat pump water heater rebates $400–$800, and geothermal rebates $500–$1,250. Customers can stack only within their service territory — these programs are mutually exclusive by utility. South Carolina also offers a 25% state income tax credit for geothermal systems. The state-administered federal IRA HEAR program (up to $8,000 for households at or below 150% AMI) and HOMES program ($2,000–$16,000) are funded with $137M from the SC Energy Office and were still pre-launch as of early 2026, with the application portal expected to open later in 2026. Utility rebates plus the 25% state geothermal tax credit (capped at $3,500/year, active through 2032) are the primary 2026 incentive layers. The state IRA HEAR program has an $8,000 per-heat-pump cap within a $14,000 household total and remained pre-launch as of June 2026.

How heat pump rebates work in South Carolina
South Carolina has a robust set of utility-funded heat pump rebates across its two large investor-owned utilities (Duke Energy Carolinas/Progress and Dominion Energy SC), the state-owned Santee Cooper, and several electric cooperatives (Berkeley, Palmetto, Blue Ridge). Typical air-source heat pump rebates run $400-$1,000, heat pump water heater rebates $400-$800, and geothermal rebates $500-$1,250. Duke Energy SC's Smart $aver was restructured in 2025 to efficiency-tiered amounts: roughly $350–$700 for an air-source heat pump replacement (up to $900 on early replacement), and $1,500 for converting from an electric furnace/strip heat to a heat pump, with higher tiers ($2,000–$2,500) for dual-fuel, cold-climate, and geothermal conversions. Dominion Energy SC offers $400–$500 for an ENERGY STAR heat pump replacement (a previously cited $650 electric-furnace tier is not supported by Dominion's current rebate page). Customers can stack only within their service territory — these programs are mutually exclusive by utility. South Carolina also offers a 25% state income tax credit for geothermal systems. The state-administered federal IRA HEAR program (up to $8,000 for households ≤150% AMI) and HOMES program ($2,000-$16,000) were still pre-launch as of early 2026, with the application portal expected to open later in 2026.

A worked example: geothermal install in Greenville
Tamika owns a 2,100 sq ft home in Greenville served by Duke Energy Carolinas. She has a half-acre lot suitable for a horizontal geothermal loop and a failing gas furnace. She gets quotes for a 3.5-ton closed-loop ground-source heat pump (WaterFurnace 7 Series, 41 EER / 5.3 COP, ENERGY STAR certified) installed at $34,800 including the loop field. Duke's restructured Smart $aver now publishes a geothermal-conversion tier of roughly $2,300–$2,500; assume $2,500 here. South Carolina's 25% state income tax credit for geothermal systems applies to her install at 25% of $34,800 = $8,700 (capped at $3,500/year, carry-forward up to 10 years if her annual liability doesn't absorb the full credit). The federal §25D residential clean energy credit at 30% adds another $10,440 in federal tax credit (uncapped, geothermal through 2032). Her household income is approximately 110% of Greenville County AMI — SC HEAR hasn't launched. Combined: $2,500 Duke + $8,700 SC + $10,440 §25D = $21,640 in rebate-plus-tax-credit stack against $34,800 installed. Net effective cost: $13,160.
Choosing a contractor in South Carolina
South Carolina licenses HVAC contractors through the SC Department of Labor, Licensing and Regulation under the Residential Builders Commission. Verify at llr.sc.gov before signing. Duke Energy Smart Saver and Dominion Energy SC rebates each have their own approved contractor lists; the lists are on duke-energy.com and dominionenergy.com. Santee Cooper EmpowerHome and electric cooperative rebates (Palmetto, Berkeley, Blue Ridge) each have their own approved contractor expectations — confirm per program. For geothermal installs claiming the SC 25% state tax credit, IGSHPA accreditation on the installer adds confidence that the loop field is correctly designed and grouted.
Common pitfalls for South Carolina homeowners
- Hitting SC tax credit liability limits. The South Carolina 25% state income tax credit for geothermal systems is non-refundable but carries forward up to 5 years. A homeowner with a $34,800 geothermal install generates an $8,700 state credit but may not have enough state tax liability in a single year to absorb the full amount. Plan for multi-year credit utilization, and consult a tax professional before assuming the full $8,700 reduces year-1 taxes.
- Confusing Duke Energy Carolinas and Duke Energy Progress. Duke Energy Carolinas and Duke Energy Progress are two separate Duke subsidiaries serving different parts of SC — DEC covers the upstate, DEP covers parts of the midlands and Pee Dee. Both run Smart Saver rebates with similar (but not identical) terms. Confirm which subsidiary serves your address by checking your monthly electric bill.

How to claim each rebate
- Get pre-approved (where required). Some utility programs require approval before install. Check program details before signing a contract.
- Use a participating contractor. Many programs require a licensed installer from an approved contractor list — especially HEEHRA, which routes through CEC-approved contractors who process the rebate at point of sale.
- Save documentation. AHRI certificate, model numbers, and itemized invoice are required for most utility rebates.
- Submit utility rebate within 60–90 days of install. Some programs are first-come first-served and close mid-year — funding can run out before the calendar year does.
