Delaware was allocated approximately $65.8 million in federal Inflation Reduction Act home energy rebate funding, with roughly $32.8 million of that set aside for the Home Electrification and Appliance Rebates program — known in federal shorthand as HEEHRA and in most state materials as HEAR. For a state with fewer than a million residents, that is a meaningful pool of money aimed squarely at low- and moderate-income households.
That said, the money has been slow to reach homeowners. This guide lays out what Delaware's program is designed to pay, who is expected to qualify, which equipment counts, and what the current launch status means for a household weighing a heat pump purchase this year.
Delaware's HEAR rebates have not launched yet. DOE approved the state's application in January 2025, but as of September 2026 DNREC still lists the program as awaiting funding before it opens to applicants.
Where Delaware's HEEHRA Program Stands In 2026
The Delaware Department of Natural Resources and Environmental Control (DNREC), through its Division of Climate, Coastal and Energy, administers both federal home energy rebate programs in the state. DNREC submitted its full application in August 2024 and originally projected a launch in the second quarter of 2025.
According to WHYY's January 2025 reporting, Delaware's application was approved in the final days of the previous federal administration. However, approval of the application and release of funds to run the program are two separate steps, and the second has not yet happened.
The Northeast Energy Efficiency Partnerships July 2025 roundup described both Delaware programs as awaiting final DOE approval. DNREC's own Home Energy Rebate Programs page still states that the rebates are expected to launch once funding is received.
Keep in mind that Delaware is not alone here. Neighboring Pennsylvania and New Jersey followed similar timelines, and our HEEHRA state-by-state status tracker shows how uneven the rollout has been across the country.

How Much Delaware's HEAR Rebates Are Designed To Pay
The dollar ceilings for HEEHRA are set in federal statute, not by the state. Delaware can design its program within those limits, and DNREC's public materials describe electrification rebates ranging from $500 to $8,000 depending on the appliance or measure.
The federal per-measure caps that apply in every participating state include:
| Qualifying upgrade | Federal HEEHRA cap | Listed by DNREC? |
|---|---|---|
| Heat pump for space heating and cooling | Up to $8,000 | Yes |
| Heat pump water heater | Up to $1,750 | Yes |
| Electrical load service center (panel) upgrade | Up to $4,000 | Yes |
| Electric wiring | Up to $2,500 | Yes |
| Insulation, air sealing, and ventilation | Up to $1,600 | Yes |
| Electric stove, cooktop, range, or oven | Up to $840 | Yes |
| Heat pump clothes dryer | Up to $840 | Yes |
| Total per household | Up to $14,000 | — |
All of these figures are maximums, not guaranteed payments. Delaware's final program rules — once published — will determine the exact amount per measure and whether any caps are set below the federal ceiling.
Federal law caps HEEHRA at $8,000 for a heat pump, $1,750 for a heat pump water heater, and $4,000 for a panel upgrade. Each household can receive no more than $14,000 in total.
Income Limits For HEEHRA In Delaware
HEEHRA is an income-qualified program by design. Eligibility is measured against area median income (AMI), and DNREC has said its electrification rebates are specifically targeted to low-income households.
The federal statute sets two tiers, and Delaware's program is expected to follow them:
- Low income (at or below 80% of AMI). These households can receive rebates covering up to 100% of the qualified project cost. The per-measure and $14,000 household caps still apply.
- Moderate income (above 80% and up to 150% of AMI). These households can receive rebates covering up to 50% of the qualified project cost. The same per-measure caps apply, so the effective maximum is often well below $8,000 on a heat pump.
- Above 150% of AMI. These households are not eligible for HEEHRA. They may still qualify for the separate HOMES whole-home efficiency rebate or for utility and Energize Delaware incentives.
For a deeper look at how these percentages translate into real dollars, see our explainer on HEEHRA income tiers. The math matters, because a moderate-income household installing a $12,000 heat pump would see a 50% rebate of $6,000 rather than the full $8,000 cap.
Households at or below 80% of area median income can receive up to 100% of project cost. Households between 80% and 150% of AMI can receive up to 50%, still subject to each measure's cap.
How Area Median Income Varies Across Delaware
AMI is not a single statewide number. The U.S. Department of Housing and Urban Development publishes income limits by county and metro area, and Delaware's three counties — New Castle, Kent, and Sussex — fall into different areas with different thresholds.
As a result, the same household income can land in different tiers depending on where you live. Household size also shifts the threshold, so a family of four in New Castle County will face a different cutoff than a single homeowner in Sussex County.
DOE guidance also allows states to accept categorical eligibility, meaning enrollment in certain means-tested programs can stand in for full income documentation. Delaware has not yet published which programs, if any, it will accept for this purpose.
Qualifying Equipment Under Delaware's Program
DNREC's published list of measures mirrors the federal statute closely. According to the department, the program is designed to cover:
- Heat pumps for space heating and cooling. This includes ducted systems and ductless mini-splits. Federal rules require ENERGY STAR certified equipment, and the state may add its own efficiency requirements.
- Heat pump water heaters. These typically replace an electric resistance or fossil-fuel tank. A heat pump water heater moves heat from surrounding air rather than generating it directly.
- Electric stoves, cooktops, ranges, and ovens. Induction and conventional electric models both fall within the statutory category, pending Delaware's final specifications.
- Heat pump clothes dryers. These are ventless units that recycle heat inside the drum. They are slower than vented dryers but use considerably less electricity.
- Electrical load service upgrades and wiring. Many older Delaware homes have 100-amp service. A panel or wiring upgrade is often the gating step before any heat pump or induction range goes in.
- Insulation, air sealing, and ventilation. These measures reduce the heating and cooling load. In fact, tightening the envelope first can let you install a smaller, less expensive heat pump.
All of the above is subject to final program rules. Of course, the equipment specification that matters most to your comfort is the one your contractor chooses, so it pays to understand the sizing question before an installer walks in.
Sizing A Heat Pump For Delaware's Climate
All three Delaware counties sit in IECC climate zone 4A, a mixed-humid zone with cold winter snaps and muggy summers. Accordingly, a heat pump here has to handle both a meaningful heating load and serious summer dehumidification.
An oversized system short-cycles in shoulder seasons, which hurts both efficiency and humidity control. This is why an ACCA Manual J load calculation — based on your home's actual insulation, air leakage, windows, and orientation — beats the rule-of-thumb tonnage estimates some contractors still use.
You can run a first-pass estimate with the ElectrifyAtlas heat pump calculator before you collect quotes. Variable-speed equipment with inverter-driven scroll compressors tends to handle Delaware's swing seasons more gracefully than single-stage units.
Most Delaware homes do not need a cold-climate-rated heat pump in the way a Vermont or Minnesota home does. However, homeowners in drafty older houses in northern New Castle County may want to compare options on our list of cold-climate heat pump brands for extra low-temperature capacity.
How HEEHRA Will Work With Other Delaware Incentives
HEEHRA will not be the only money on the table once it launches. Delaware homeowners already have access to Energize Delaware, the state's Sustainable Energy Utility, which runs Home Performance with ENERGY STAR and related efficiency programs.
What's more, customers of Delmarva Power, the Delaware Electric Cooperative, and the state's municipal electric utilities may find separate efficiency incentives from their own provider. Amounts and eligibility change by program year, so confirm the current terms directly with each program before counting on a figure.
Federal rules generally prevent two federal rebates from paying for the same upgrade. In other words, a household cannot claim both a HOMES rebate and a HEEHRA rebate for the same heat pump, although the two programs can cover different measures in the same home.
Delaware households cannot use HOMES and HEAR for the same upgrade. They can pair a HEAR heat pump rebate with a HOMES-funded insulation project, and may layer non-federal utility incentives where program rules allow.
The order in which you apply can affect the total you receive. Our guide to rebate stacking and application order walks through the sequencing, and the broader rebate stacking guide covers how point-of-sale rebates interact with utility incentives.
The Federal Tax Credit Picture
Keep in mind that the federal tax credit landscape changed at the end of 2025. The residential clean energy credit for solar (25D) expired on December 31, 2025, and the 25C energy efficient home improvement credit also ended for property placed in service after that date.
Therefore, a Delaware homeowner installing a heat pump in 2026 should not assume any federal tax credit will offset the cost. Our federal tax credit status page tracks what remains in effect.
How Delaware Compares To Its Neighbors
The Mid-Atlantic has been a mixed picture for HEEHRA. Delaware's allocation is smaller than those of Maryland, Pennsylvania, and New Jersey, which reflects its population rather than any difference in per-household rebate caps.
Because the per-measure caps are federal, a low-income Delaware household is expected to be eligible for the same $8,000 heat pump ceiling as a qualifying household in Baltimore or Philadelphia. The difference lies in how quickly each state opens its program and how long its allocation lasts.
For comparison, homeowners near the state line can review utility programs next door, such as BGE rebates in Maryland, PECO rebates in southeastern Pennsylvania, and PSE&G rebates in New Jersey. These pages illustrate how utility incentives in the region are typically structured.
What Delaware Homeowners Can Do While Waiting
A pending program creates a real decision for anyone whose furnace or air conditioner is near the end of its life. The considerations below depend on where you are in the process.
Here's how the decision tends to break down by phase:
- Equipment still working. If your current system has a few seasons left, waiting for HEAR to launch preserves your eligibility. In the meantime, a Manual J load calculation and an energy audit through Energize Delaware can position you to move quickly once applications open.
- Equipment failing now. If your system has failed in the middle of winter or summer, waiting for a federal program with no confirmed launch date may not be practical. Existing Energize Delaware and utility incentives can still reduce the cost of a heat pump today.
- Planning a panel upgrade. Note that electrical service upgrades are one of the larger HEEHRA categories at up to $4,000. If a panel upgrade is needed but not urgent, the timing of HEAR's launch may matter for your budget.
HEAR is not expected to rebate heat pumps installed before it launches. Most states cover only projects started after launch, so assume a system installed today is ineligible unless DNREC says otherwise.
Remember that HEEHRA is designed as a point-of-sale rebate in most states, meaning the discount is applied through a participating contractor rather than mailed back later. As a result, the contractor you choose will likely need to be enrolled in Delaware's program once it opens.
Key Questions To Ask Before You Sign A Contract
Whether you install now or wait, a few questions can protect you from overpaying or losing eligibility. After all, a heat pump is a 15-year decision, and the rebate is only one part of the cost.
Some questions worth putting to any Delaware contractor include:
- Will you perform a Manual J load calculation? A written load calculation is the clearest sign that the system is sized for your home rather than your old equipment.
- Is the proposed equipment ENERGY STAR certified? HEEHRA requires it, and utility programs frequently do as well. Ask for the AHRI certificate number for the matched system.
- Do you plan to enroll in Delaware's HEAR program? Contractors who intend to participate will generally be watching DNREC's updates closely.
- What incentives are included in this quote? A quote should list each rebate separately, with the program name, so you can verify each one independently.
Overall, a contractor who can answer all four questions clearly is more likely to deliver a system that performs well in Delaware's mixed-humid climate. For more on the full federal program, visit our HEEHRA guide.
The Bottom Line On HEEHRA In Delaware
Delaware's HEAR program is designed, funded on paper at roughly $32.8 million, and approved at the application stage, but it has not opened to homeowners. Once it does, income-qualified households can expect access to the same federal caps as every other state — up to $8,000 for a heat pump and $14,000 in total.
Until then, the most useful steps are verifying status with DNREC, understanding your income tier, and getting an honest load calculation. We will update this page as DNREC publishes final program rules and a launch date.
