Energize Delaware Rebates
Energize Delaware rebates can put as much as $2,200 toward a central heat pump and $3,300 toward a heat pump working alongside a furnace. Ductless mini-split rebates depend on how many indoor units you add, up to a total of $5,500. Before anything else, you have to complete a Home Energy Assessment, and your contractor has to lock in the rebate before any work begins.

Payments for Heat Pumps and Water Heaters
The figures in this table come from the current incentive sheet, and Tier 2 equipment must meet higher efficiency ratings than Tier 1. A Standard rebate cannot exceed 50% of your installation cost, and an Assisted rebate cannot exceed 75%.
| What you install | Rebate | Who | Conditions |
|---|---|---|---|
| Heat Pumps Tier 2 (>=17 SEER2, >=12.0 EER2, >=8.2 HSPF2, multi-stage) | $1,600 | Any income | Capped at 50% of installed cost; after a Home Energy Assessment; program-participating contractor; reservation before work |
| Heat Pumps Tier 2 (Assisted) | $2,200 | Income-qualified | Assisted HPwES: capped at 75% of installed cost; income-qualified, military and active-duty first responders |
| Heat Pumps Tier 1 (>=16 SEER2, >=11.5 EER2, >=7.8 HSPF2, multi-stage) | $800 | Any income | Capped at 50% of installed cost |
| Heat Pumps Tier 1 (Assisted) | $1,200 | Income-qualified | Capped at 75% of installed cost |
| Mini-Split HP Tier 2 (>=20 SEER2, >=12.0 EER2, >=8.6 HSPF2) | $1,000 plus $550 per additional indoor unit; mini-split rebates capped at $4,000 per customer | Any income | Tier 1 (>=17 SEER2) pays $550 plus $350 per additional indoor unit |
| Mini-Split HP Tier 2 (Assisted) | $1,700 plus $900 per additional indoor unit; capped at $5,500 per Assisted customer | Income-qualified | Tier 1 pays $1,000 plus $600 per additional indoor unit |
| Heat Pump Water Heater | $1,100 | Any income | Capped at 50% of installed cost |
| Heat Pump Water Heater (Assisted) | $1,350 | Income-qualified | Capped at 75% of installed cost |
No matter how many indoor units you add, the rebate tops out at $4,000 for a standard customer and $5,500 for an Assisted one. Example: a Tier 2 mini-split that has three indoor units earns a standard rebate of $1,000 plus $550 for each of the two extra units.
This program does not cover geothermal heat pumps. Those go through the DNREC Green Energy Program rather than this one.
About Energize Delaware
Energize Delaware is the public name of the Delaware Sustainable Energy Utility, a nonprofit organization that operates home energy rebate programs across Delaware. Its heat pump rebates are part of Home Performance with ENERGY STAR, which is currently running.
A second version of that program, called Assisted Home Performance with ENERGY STAR, pays more. It covers as much as 75% of your installation cost, rather than 50%, and the rebate amounts are bigger. You may qualify if your household is under the income limits, if you serve in the military or as an active-duty first responder with no income test, or if your home sits inside one of Delaware's designated downtown development districts.
Who Is Eligible?
Your home has to be residential property in Delaware. Either the registered homeowner or, with the owner's okay, a renter can apply.
If a building has more than four units, it still counts as long as it is no more than three stories tall and at least 10 years old. Any work finished before the assessment does not count, and neither does equipment you install on your own.
Steps to Get the Rebate
Follow the order below. If anything gets installed before the reservation is approved, the rebate is gone.
- Schedule a Home Energy Assessment. An energy advisor visits your home and looks at where energy is used and where it escapes. You pay $50 toward the visit, $100 if the home is larger than 3,000 square feet, and only $25 if your income qualifies you.
- Sit down with a program-participating contractor, review the assessment report, and pick which upgrades to make.
- Sign an agreement with the contractor. Before starting the job, the contractor submits the rebate reservation, which is the request that holds the money for your project.
- Once the reservation is approved, the contractor installs the equipment.
- The energy advisor returns to do a final inspection.
- The contractor submits the final application. After approval, your rebate check comes in six to eight weeks.
Efficiency Ratings Your Equipment Needs
Every heat pump has efficiency ratings printed on its label. SEER2 and EER2 tell you how efficiently it cools, and HSPF2 tells you how efficiently it heats. The higher the number, the less energy it uses. Your contractor checks your unit's numbers against the program rules.
| Type of equipment | SEER2 | EER2 | HSPF2 |
|---|---|---|---|
| Tier 1 central heat pump (multi-stage) | 16 or more | 11.5 or more | 7.8 or more |
| Tier 2 central heat pump (multi-stage) | 17 or more | 12.0 or more | 8.2 or more |
| Tier 1 mini-split | 17 or more | ||
| Tier 2 mini-split | 20 or more | 12.0 or more | 8.6 or more |
A hybrid setup counts only when the heat pump is Tier 2 and the furnace it works with carries a 96 AFUE rating or higher.
Bonuses and the Efficiency Loan
At the assessment, the advisor puts in as much as $250 of energy-saving products, and you pay nothing extra for them. Adding air sealing to your heat pump project earns a $300 bundling bonus, or $350 under the Assisted program. Beginning July 1, 2026, the temporary incentive bonus rises from 20% to 25%.
Need help with the remaining cost? The Home Energy Efficiency Loan offers loans from $1,000 to $50,000 with a 5.99% APR, and you can take up to 10 years to repay. You only qualify if your project receives an Energize Delaware rebate.
Questions People Ask
Does the federal energy efficiency tax credit survive into 2026?
No. The credit went away under a federal law signed on July 4, 2025, which covers equipment put into service after December 31, 2025. That means a heat pump installed in 2026 won't qualify, so these state rebates matter even more.
How does the Delaware Home Energy Rebate program fit in?
DNREC, the state energy office, runs this separate program, which is funded by the federal government, and it has not launched so far. DNREC says the program will begin once the funding arrives. WHYY reported in January 2025 that the U.S. Department of Energy approved Delaware's application, worth close to $66 million.
Can You Trust Energize Delaware?
Yes. Energize Delaware is the state's Sustainable Energy Utility, a nonprofit created to run Delaware's energy programs. An official incentive sheet lists its rebate amounts and rules. The sheet carries a 2025 date, and it remains the document linked from the 2026 program page.
