Dominion Energy South Carolina runs the electric meters across most of the Lowcountry, and its rebate sheet is where the heat pump money lives for those addresses in 2026. The structure is tiered, and the tiers tell you what the utility wants. The top line pays $650 for replacing an electric furnace with a heat pump, the most expensive-to-run heating configuration on its grid. The central air conditioner and heat pump tiers pay $400 to $500 for replacement projects. The tiers are alternatives by application, not a stack: a project collects one line, and which line depends on what the new machine replaces. With no live state program and the federal 25C and 25D credits ended December 31, 2025, this sheet, plus Duke's and Santee Cooper's in their territories, is the entire incentive conversation in South Carolina, and reading the tier structure correctly is the first skill this page teaches.
The Program in One Table
| Dominion tier | 2026 amount | Condition |
|---|---|---|
| Electric furnace to heat pump | $650 | Retiring an electric furnace; Dominion residential electric customers |
| Central AC / heat pump tiers | $400 to $500 | Replacement projects; tier by efficiency |
| Stacking | Not additive | Tiers are alternatives by application |
The Tier Follows What You Retire
The single most common misreading of a tiered sheet is treating the top number as the default. Dominion's $650 is not the heat pump rebate; it is the electric-furnace-retirement rebate. A household replacing an aging heat pump or central air conditioner is shopping in the $400 to $500 tiers, and a quote that pencils the $650 into a changeout project has claimed a tier the application will not survive. The check takes one sentence: which tier does this project qualify for, and what does the new machine replace? A contractor who answers precisely has read the sheet; one who rounds up has not.
Why the Electric Furnace Pays the Most
The economics behind the top tier are the same economics that make the conversion case in our fuel comparison the strongest in the region. An electric furnace converts one unit of electricity into one unit of warmth, full price, every hour; a heat pump on the same meter moves two to three units of warmth per unit purchased. The utility pays $650 to retire the furnace because that furnace is the most expensive warmth on its winter grid, and the household collects twice: once in the rebate, then every month in a heating share that shrinks toward a half or a third. For the older stock from West Ashley to North Charleston where electric furnaces still run, this is the sheet's best line aimed at the region's best project.
What the Money Points At in the Lowcountry
Map the tiers onto the housing stock and the program comes into focus. The electric-furnace line points at the older ranches and rentals across West Ashley, North Charleston, and Goose Creek where resistance furnaces still hum. The replacement tiers point at the subdivision stock of Mount Pleasant and Summerville, where the most common project is an aging heat pump or air conditioner replaced under July duress. The historic peninsula, Downtown, South of Broad, Cannonborough, holds the conversions where resistance heat hides behind renovations and where the operating case is strongest even before the rebate. In every case the rebate improves arithmetic that already cleared; it should never manufacture it.
The Rest of the State's Map
Dominion is the Lowcountry's meter, but this storefront's territory runs statewide, and the program follows the bill. Where Duke Energy Carolinas or Progress serves, Smart Saver pays $500 for replacing an existing heat pump and $1,000 for replacing electric strip heat, alternatives rather than a stack. Santee Cooper, the state-owned utility, runs programs that vary and gets a direct confirmation, not an assumption. The full statewide map with every condition lives in our rebates guide. Territory decides everything; the name at the top of the bill names your program.
How the Money Is Collected
The sequence is short and worth running in order. First, confirm Dominion Energy South Carolina bills your electric meter; the program follows the bill, not the address. Second, confirm which tier the proposed project qualifies for, stated against what the new machine replaces, in writing. Third, confirm the proposed equipment meets the tier's efficiency requirements, which the contractor should state from the sheet rather than from memory. Fourth, get the expected amount as a named line on the quote, along with who files the application and when. Keep the invoice and the confirmation together afterward; that pair is the paper trail if anything needs chasing.
The Program as a Contractor Test
A tiered sheet makes a sharp vetting instrument. A contractor who names the correct tier for your project, states the efficiency requirement, and puts the amount and filing responsibility on the quote has demonstrated current program knowledge. One who quotes the $650 on a changeout, or stacks tiers the program calls alternatives, has misread a checkable document. And one who still cites the federal credit as live money is working from a sheet that expired December 31, 2025. Staleness about money travels with staleness about everything else, including the load calculations, capacity tables, and salt-air specifications in our cold-weather guide that matter far more than any rebate.
What the Rebate Should Not Do
Six hundred fifty dollars improves a decision that already cleared; it should never be the decision. A household chasing the top tier into the wrong project, or rushing a specification to hit a filing date, has traded fifteen years of comfort for a three-figure check, and on this coast the comfort at stake is mostly summers. The correct order is fixed: load calculation first, capacity at the design condition second, specification and price third, program money last, subtracted from arithmetic that already stood on its own, per the sequence in our contractor guide.
After the Install, One Meter Conversation
The rebate arrives once; the bill arrives monthly, and it is worth one deliberate look the first year. An electric-furnace convert should see the heating share of winter bills fall toward a half or a third at the same meter. A heat pump replacer should see the rare cold snaps flatten and the summer improve. Everyone should see the cooling season improve, which in the Lowcountry is by far the larger number and the longer season. If the shape is wrong, the specification was, and the commissioning conversation happens under warranty rather than in year five.
The Short Version
Dominion Energy South Carolina pays $650 for retiring an electric furnace and $400 to $500 on its central AC and heat pump replacement tiers, alternatives by application, never additive. The tier follows what you retire, so the first question on any quote is what the new machine replaces. Duke's Smart Saver and Santee Cooper's programs cover the rest of the state by meter. The federal credits ended December 31, 2025. Match the tier, name the line, keep the paper, and spend your real attention on the load calculation and the capacity table.
