Delaware Heat Pump Rebates

What's available in Delaware

Delaware’s heat pump rebate landscape is anchored by Energize Delaware (the Delaware Sustainable Energy Utility), which runs the statewide Home Performance with ENERGY STAR rebate program funded primarily through RGGI proceeds and a Delmarva Power surcharge. Delmarva Power customers access utility heat pump rebates through this same program rather than a separate utility-branded rebate. Delaware Electric Cooperative and DEMEC municipal utilities (Newark, Dover, Lewes, Milford, Seaford and others) run smaller standalone heat pump and heat pump water heater incentives. DNREC plans to launch the federal IRA HEAR/HEEHRA program in 2026 with up to $8,000 in income-qualified heat pump rebates.

How heat pump rebates work in Delaware

Delaware's heat pump rebate landscape is anchored by Energize Delaware (the Delaware Sustainable Energy Utility), which runs the statewide Home Performance with ENERGY STAR rebate program funded primarily through RGGI proceeds and a Delmarva Power surcharge. Top-tier ducted air-source rebates run up to $1,600 (Tier 2), mini-splits up to $4,000 per HPwES customer. Delmarva Power customers access utility heat pump rebates through this same program rather than a separate utility-branded rebate — Delaware is one of the few states where the dominant electric utility's HVAC rebate is administered through the state efficiency entity rather than the utility directly. Income-qualified households (≤80% AMI, plus Downtown Development District residency or active military/first-responder status) can claim the Assisted HPwES tier at up to $2,200 (Tier 2) with the mini-split cap raised to $5,500. Delaware Electric Cooperative and DEMEC municipal utilities (Newark, Dover, Lewes, Milford, Seaford) run smaller standalone heat pump and HPWH incentives. DNREC plans to launch IRA HEAR in 2026 with up to $8,000 layered on top — confirm program status before relying on it.

A worked example: mini-split retrofit in Newark

Hannah owns a 1,400 sq ft home in Newark, currently heated by a 30-year-old oil furnace with no central AC. She's a Delmarva Power electric customer for electric service and Delaware Sustainable Energy Utility for efficiency programs (same address, different administrative paths). She gets quotes for a 2-ton ductless mini-split system (three indoor heads, NEEP cold-climate certified) plus retention of the oil furnace as backup for cold snaps. Installed cost: $13,500. Because mini-splits cap at $4,000 per HPwES customer at the standard tier, she qualifies for $4,000 in Energize Delaware rebate at the standard income tier (assuming household income above 80% AMI). She's required to complete a Home Energy Assessment by an approved Energize Delaware contractor as a prerequisite — that's a $100 cost typically rolled into the project. The Newark Municipal Electric Department (DEMEC) layers a small additional rebate (verify current amount), and the Newark-specific Downtown Development District designation would qualify her for the $5,500 Assisted tier if her household income drops below 80% AMI in a future year. Combined stack at the standard tier: $4,000 against $13,500. Net out-of-pocket: $9,500.

Choosing a contractor in Delaware

Delaware licenses HVAC contractors through the Delaware Division of Professional Regulation — verify license status before signing. Energize Delaware HPwES rebates require an approved Energize Delaware contractor; the contractor schedules the prerequisite Home Energy Assessment, files the rebate paperwork, and handles the documentation flow with the Delaware Sustainable Energy Utility. A non-approved contractor cannot file HPwES rebates. The approved contractor list is on energizedelaware.org. For DEMEC municipal customers (Newark, Dover, Lewes, Milford, Seaford), the muni's own efficiency program may have a separate approved contractor list — confirm at the quote stage.

Common pitfalls for Delaware homeowners

• Skipping the Home Energy Assessment prerequisite. Energize Delaware HPwES rebates require a Home Energy Assessment by an approved Energize Delaware contractor before the install. A homeowner who installs equipment first and applies for the rebate afterward will be denied. The assessment is roughly $100 and typically rolled into the project quote — confirm with your contractor that it's scheduled before equipment is ordered.
• Confusing Delmarva Power and Delaware Electric Cooperative. Delmarva Power serves roughly two-thirds of Delaware (most of New Castle County, most of Kent County, and Sussex County). Delaware Electric Cooperative serves a chunk of southern Delaware and rural pockets. The two utilities have different rebate paths — Delmarva customers use Energize Delaware HPwES, DEC members use the cooperative's own rebate program. Check your monthly electric bill to confirm which utility serves your address.

How to claim each rebate

1. Get pre-approved (where required). Some utility programs require approval before install. Check program details before signing a contract.
2. Use a participating contractor. Many programs require a licensed installer from an approved contractor list — especially HEEHRA, which routes through CEC-approved contractors who process the rebate at point of sale.
3. Save documentation. AHRI certificate, model numbers, and itemized invoice are required for most utility rebates.
4. Submit utility rebate within 60–90 days of install. Some programs are first-come first-served and close mid-year — funding can run out before the calendar year does.
