Heads up: the federal 25C tax credits that covered heat pumps ($2,000), high-efficiency AC/furnaces ($600), and windows ($600) expired for any system installed after December 31, 2025. In 2026, South Carolina homeowners should focus on utility and state programs instead.
| Program | Amount | 2026 status |
|---|---|---|
| Federal 25C — heat pump / AC / windows | Up to $2,000 | ❌ Expired for installs after 12/31/2025 |
| Duke Energy rebates & tune-up (Upstate / Greenville) | $50–$450+ | ✅ Utility program — verify current funding |
| Dominion Energy programs (Midlands / Columbia) | Varies | ✅ Utility program — check availability |
| SC Home Energy Rebates (HOMES / HEAR) | Up to $8,000 | ✅ Income-qualified — check SC Energy Office availability |
Where the 2026 savings actually are
In South Carolina your utility depends on where you live: Duke Energy serves the Upstate (Greenville), while Dominion Energy serves the Midlands (Columbia). Getting that right is how you avoid applying to the wrong program and missing money. The other big saving is the one that shows up every month: a high-efficiency system trims the bill through the long cooling season. Estimate your project on the South Carolina HVAC calculator, or read what a heat pump is before you shop.
