South Carolina's 2026 heat pump money is utility money, and this storefront's territory runs the whole state, which means one page has to hold three program worlds. Santee Cooper, the state-owned utility, runs its own programs that vary, which makes a direct confirmation call the only honest number for those meters. South Carolina's home energy rebate program is not open as of 2026-10-07 (https://energy.sc.gov/rebates). Check your state energy office for current rebates. Program terms checked 2026-10-07.
The Map in One Table
| Program | 2026 amount | Condition |
|---|---|---|
| Santee Cooper | Varies | State-owned utility; confirm any current rebate directly |
Dominion: The Electric-Furnace Line Is the Headline
The tiers are alternatives by application, not a stack, so a project collects one line, and which line depends on what the new machine replaces. The full mechanics, and the collection sequence, live in our Dominion guide.
Duke Territory: The Strip-Heat Doubling
The doubling is the program's economics showing: strip heat is the grid's most expensive warmth, and the utility pays twice as much to retire it. Either error is checkable before any equipment is discussed.
Santee Cooper: The Confirmation Call
Santee Cooper, the state-owned utility, runs programs that vary, and this page will not pretend otherwise. For those meters the honest procedure is one call to the utility, or one written confirmation from the contractor, stating what rebate exists for the proposed project this year, before any program dollars appear in the arithmetic. A quote that pencils in a Santee Cooper figure without a source has invented it; a quote that says "confirm with the utility, here is the number without it" is telling the truth.
The Stale Quote Test
The map doubles as a contractor filter anywhere in the state. The bidder who states the programs as this page states them, tiers, conditions, and confirmations included, has passed an honesty test before any equipment is discussed, per the sequence in our contractor guide.
Why the Project Clears Without the Rebate
Charleston's winters are mild, among the gentlest winter exams the technology faces, and the cooling season runs long, humid, and hard. The economics rest on the operating math: against strip heat, electric furnaces, and aging early-generation heat pumps, the arithmetic clears over the machine's life without a dollar of subsidy, and the same machine replaces the air conditioner that was already the biggest line on the summer bill. A rebate should never be the reason a project happens; it is the bonus for a project that already cleared, per the specification discipline in our cold-weather guide.
The Housing Stock Angle
The programs read the same while the projects differ. Downtown, South of Broad, and Cannonborough carry the historic single houses and conversions where ductless and compact-ducted systems earn their keep, where usable ducts thin out and the electric resistance heat hiding in older renovations makes the strongest operating case in the Lowcountry. Mount Pleasant, Summerville, Goose Creek, and North Charleston carry the ducted subdivision stock where the most common project is replacing an aging heat pump or air conditioner, most often triggered by a machine that quit in July, which maps to Dominion's replacement tiers. The islands, Isle of Palms, Daniel Island, James Island, Johns Island, add the coastal variables: salt air on the outdoor unit and, in flood zones, equipment elevated on platforms, both belonging in the conversation before a price does.
Renters and Landlords
The rebate follows the buyer of the equipment, which means the owner. The Lowcountry rental stock carries much of its most expensive heat as electric resistance, warming tenants who cannot replace it, and the program map pays owners directly to fix exactly that: Dominion's top line retires electric furnaces, Duke's top tier retires strip heat. The owner's case needs no charity: a paid rebate, a large operating improvement, better cooling through the long season, and a property that rents better for both. A tenant's cheapest move is forwarding this page to whoever holds the deed.
Collecting Cleanly
The checklist is short and territory-first. Confirm which utility bills your meter, because the program follows the bill: Dominion for most of the Lowcountry, Duke Carolinas or Progress elsewhere, Santee Cooper where the state-owned utility serves. Confirm which tier your project actually qualifies for, stated against what the new machine replaces. Get the expected amount as a named line on the quote, along with who submits the application. For Santee Cooper meters, get the program confirmation in writing before counting anything. Keep the invoice with the confirmation as the paper trail.
The Short Version
Santee Cooper varies and gets confirmed directly. Confirm the program by meter, match the tier to what the machine replaces, name the line, keep the paper, and spend your real attention on the load calculation and the capacity table, priced in our installation cost guide.
