How does the Energize Delaware program work?
It starts with a home energy assessment ($50, or $25 for the assisted tier), followed by recommended improvements done by participating contractors.
Rebates are capped at the listed maximum or a share of installed cost, whichever is lower, and some equipment rebates require air sealing within a set window.
What happened to the federal HVAC tax credit?
The federal 25C Energy Efficient Home Improvement Credit ended for property placed in service after December 31, 2025.
If you installed qualifying equipment in 2025, it may still apply to your 2025 tax return; consult a tax professional.
What about the IRA home energy rebates?
Delaware’s DNREC has described Home Efficiency and Home Electrification rebate programs funded by the Inflation Reduction Act.
Check DNREC for current launch status and eligibility; these programs are income-based and change over time.
How do I make sure I actually get the rebate?
Confirm the contractor participates, get equipment model numbers matched to program requirements before installation, and keep all paperwork.
Ask who submits the rebate paperwork and when payment arrives.
