Entergy Mississippi runs the electric meters across Central Mississippi and much of the state, and its rebate sheet is where the heat pump money lives for those addresses in 2026. The headline is the largest single line in Mississippi: up to $1,100 on a qualifying high-efficiency heat pump or air conditioner. The sheet's second line is the one most quotes miss: a heat pump water heater rebate up to $750 that stacks on the same project as a separate measure, which means a household replacing both machines at once can collect toward $1,850 on one invoice. With no state program and the federal 25C and 25D credits ended December 31, 2025, this sheet, plus the Mississippi Power and TVA programs in the state's other territories, is the entire incentive conversation in Mississippi, and reading it correctly takes about as long as this page.
The Sheet in One Table
| Line | 2026 amount | Condition |
|---|---|---|
| High-efficiency heat pump or AC | Up to $1,100 | Entergy Mississippi residential customers; confirm SEER2 tier and current amount |
| Heat pump water heater | Up to $750 | Separate measure; stacks on the same project |
| Combined project ceiling | Toward $1,850 | Both measures on one invoice |
| Verification | Required | Tier and amount confirmed in writing at quote time |
The Big Line, and Its Two Conditions
Eleven hundred dollars is real money on a project whose bands run from a few thousand for single-zone ductless to the deep five figures for a whole-home conversion, per our installation cost guide. The conditions are few and checkable. First, the efficiency tier: "high-efficiency" is a defined SEER2 threshold, not a compliment, and the proposed machine either meets the current tier or it does not, stated from the sheet rather than from memory. Second, the amount: "up to" means the payout scales with the tier, so the quote should carry the confirmed figure for the specific machine proposed, with a confirmation date, as a named line. Both checks take a contractor minutes, and a contractor who resists them has told you something useful early.
The Water Heater Rider, the Sheet's Quiet Second Line
The $750 heat pump water heater rebate is the piece of program fluency that separates contractors who read the current sheet from those reciting an old one. It pays as a separate measure on the same project, which creates the rare case where adding scope lowers the net cost of the added scope: a household whose water heater is within a few years of its own funeral folds the replacement into the HVAC project, collects both lines on one invoice, and retires two resistance appliances in one permit cycle. It is not money worth designing a project around on its own, but on a project already happening it is the cheapest $750 in the state, and a bidder fluent in the sheet prices it without being asked.
What the Money Points At
An Entergy rebate points at the metro's two big project families. The subdivision rings, Madison, Ridgeland, Brandon, Flowood, Pearl, and Clinton, hold aging heat pumps and air conditioners whose July failures trigger most of the metro's purchases, where the rebate rides a replacement that was happening anyway. The older stock, Fondren, Belhaven, and Downtown Jackson, holds the electric resistance heat whose conversion carries the strongest operating case in the metro, per our fuel comparison. In both families the rebate improves arithmetic that already cleared; it should never manufacture it.
The Rest of the State's Map
Entergy is not Mississippi's only program world, and the territory carve matters because the program follows the bill. The southeast runs on Mississippi Power's per-ton sheet: roughly $100 to $200 per ton by SEER2 tier, ductless at $200 per ton, about $600 for a typical 3-ton system. The northeast runs on TVA EnergyRight through the local power associations, Tupelo Water & Light, Tombigbee EPA, Northeast Mississippi EPA, Pontotoc EPA, Alcorn County EPA, and 4-County EPA among them: up to $800, but only replacing existing electric heat, only through a Quality Contractor Network installer, on a claim clock of contractor within 90 days and homeowner within 60, funded through 2027. The three worlds never combine on one meter, and the full statewide map lives in our rebates guide.
The Sheet as a Contractor Test
Even before equipment is discussed, the program sorts bidders. A contractor who quotes the Entergy line fluently, tier checked against the current sheet, amount confirmed in writing, water heater rider priced where the project touches it, has demonstrated current program knowledge. One who carries the $1,100 as an unverified round number is reciting a brochure. One who promises TVA money on an Entergy meter has misread the service map, and one who 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 capacity tables in our cold-weather guide that matter far more than any rebate.
How the Money Is Collected
The sequence is short and worth running in order. First, confirm Entergy Mississippi bills your electric meter, because the program follows the bill and the state holds three worlds. Second, confirm the proposed machine meets the current efficiency tier, in writing against the sheet. Third, confirm the current rebate amount for that tier, with a date. Fourth, price the water heater line if the project can carry it. Fifth, get every expected amount as a named line on the quote, along with who files the application and when, in writing. Keep the invoice and the confirmations together afterward; that pair is the paper trail if anything needs chasing.
What the Rebate Should Not Do
Eleven hundred dollars improves a decision that already cleared; it should never be the decision. A household letting the rebate pick the machine, or rushing a specification to catch an amount nobody confirmed, has traded fifteen years of comfort for a check that covers a fraction of one summer's cooling. The correct order is fixed: load calculation first, capacity at the mid-twenties 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 for fifteen years. A strip-heat 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 this metro is the larger number and the longer season. A household that collected both lines should also see the water heating share shrink. If the shape is wrong, the specification was, and that conversation happens best under warranty rather than in year five.
The Short Version
Entergy Mississippi pays up to $1,100 on a qualifying high-efficiency heat pump or air conditioner, plus up to $750 on a heat pump water heater as a separate measure that stacks on the same project, toward $1,850 on one invoice. Confirm the tier, confirm the amount, name the lines, price the water heater rider when the project can carry it, and keep the paper. The southeast and northeast run their own program worlds that never mix with this one. The federal credits ended December 31, 2025. Then spend your real attention where the money actually lives: the load calculation and the capacity table.
