Claiming Delaware Heat Pump Rebates Step by Step

Up to 50% of your installed cost is covered by the Energize Delaware Home Performance program, most homeowners' starting point. Self-installed systems and any work begun early are both excluded, so take these steps in order:

  1. Book a Home Energy Assessment with a $50 co-pay, or $100 for homes over 3,000 square feet.
  2. Free energy-saving products, up to $250 in value, are installed by your advisor at the visit.
  3. A participating contractor reviews your report with you; sign an agreement, and they can reserve your funds ahead of the work starting.
  4. Your rebate check arrives in six to eight weeks once the final advisor inspection is done after installation and approval is complete.

A five-year parts and labor warranty is required for members using the Delaware Electric Cooperative grant, from a qualified contractor or an approved self-install. Email grants@delaware.coop with the signed form, invoice, and equipment sheet, and apply within 60 days for water heaters.

Lower-Income Homes: Higher Rebates and Free Upgrades

Assisted Home Performance is available to households with limited income, and it lifts the Energize Delaware rebate cap so it covers 75% of installed cost. The first assessment fee you pay falls to $25, and ductless mini-split rebates per customer can total as much as $5,500. Residents of the Downtown Development District qualify, as do income-qualified owners, approved tenants, and active-duty or military first responders of any income.

Households making under $31,920 (one person) or $66,000 (four persons) can get free upgrades from the Delaware Weatherization Assistance Program. For the Department of Natural Resources and Environmental Control, the Energy Coordinating Agency delivers these services across the state.

Separate federal Home Energy Rebates with close to $66 million behind them are still in planning and not open yet. Your household income and home type will set where whole-home rebates fall between $2,000 and $8,000. Appliance rebates will go to low-income homes earning no more than 150% of the area median income, the middle point of what local families earn.

Loans, Tax Rules, and Heating Fuels in Delaware

Fuel oil or propane heats one Delaware home in six, and electric heat serves almost four homes in ten. Utilities must draw 40% of their power from renewable sources by 2035 under Delaware energy law, with 10% from solar. Energize Delaware, a nonprofit, serves as the state's Sustainable Energy Utility and gets its funding through the Regional Greenhouse Gas Initiative.

A $300 bundling bonus applies when you add air sealing to a new heat pump, or $350 for Assisted customers. As of July 1, 2026, Energize Delaware will also boost the limited-time bonus on incentives, taking it from 20% up to 25%. Through the Home Energy Efficiency Loan, projects that qualify can borrow between $1,000 and $50,000, with 5.99% interest, for terms of up to ten years.

For equipment installed after the December 31, 2025 cutoff, the federal Section 25C tax credit was eliminated through Public Law 119-21.

Common Questions About Delaware Heat Pump Rebates

If I install a heat pump in Delaware, which rebates can I claim?

Standard air-source units aside, Energize Delaware pays $2,250 when you combine a heat pump with a furnace, and Assisted customers get $3,300. For heat pump water heaters, the standard amount is $1,100, the Assisted amount is $1,350, and Delaware Electric Cooperative pays $300. Energize Delaware does not cover geothermal systems, which instead use the state Green Energy Program.

Are any federal tax credits for heat pumps coming in 2026?

Heat pumps placed in service during 2026 do not qualify for any federal Section 25C tax credit. The credit no longer applies after December 31, 2025; Congress ended it through the One, Big, Beautiful Bill, signed into law on July 4, 2025. The Internal Revenue Service guidance is set out in Fact Sheet FS-2025-05, which the IRS issued on August 21, 2025.

How big a rebate can I expect on a 2,000 square foot Delaware home?

The $100 fee only kicks in above 3,000 square feet, so a 2,000 square foot Delaware home owes the standard $50 assessment co-pay. Delaware Electric Cooperative pays per cooling ton, from $500 to $1,000, using SEER2, the efficiency rating for seasonal cooling printed on the label. Buildings with more than four units must be no taller than three stories and at least ten years old.

Are free heat pumps available anywhere in Delaware?

Standard rebates cover at most 50% of installed cost, and Assisted rebates at most 75%, so Energize Delaware never pays the whole price. To ask about upcoming federal appliance rebates, low-income households can email DNREC.EnergyPrograms@appliedenergygroup.com and reach state energy customer support. The weatherization income limit also rises by $11,360 for each extra person in families larger than eight.
