The DC Sustainable Energy Utility opened its new program year on October 1, 2026, with a fresh residential heating and cooling rebate form. For anyone planning a mini split, Roomwise DC Mini Splits has summarized what that form says, what it asks for, and how the rebate fits into a job.
What the rebate pays
DCSEU pays by efficiency tier and by the fuel the new system replaces. Replacing gas heat earns several times the electric-to-electric amount.
| Ductless mini-split heat pump | Replaces electric heat | Replaces gas heat |
|---|---|---|
| Tier 1, ENERGY STAR Certified | $1,000 | $4,000 |
| Tier 2, ENERGY STAR Most Efficient | $1,500 | $5,000 |
The tiers have minimum ratings for the outdoor unit. Tier 1 needs at least SEER2 15.2, EER2 11.7 and HSPF2 7.8. Tier 2 needs at least SEER2 16, EER2 12 and HSPF2 9. The equipment we specify in a written plan names which tier it meets.
DCSEU caps rebates at $15,000 per household per program year. The form says amounts can change at any time, and every rebate is subject to available funds, so treat these figures as current rather than fixed.
Who qualifies
The rebate is for residential customers in DC: owners or occupants of a single-family home of four units or less, plus individual condo and co-op unit owners. There’s no income limit.
- New equipment, installed to code and kept in place for at least a year
- Connected to the utility account named on the bill
- Open to inspection if DCSEU asks
For condo owners, DCSEU’s rules are only half of it; the building’s documents decide where an outdoor unit can go. See condo mini split installation.
What the application needs
Every application goes in with paperwork from the install. Most of it comes from the installer, so it helps to know the list before the job starts.
- The DOB permit for the install, with contractor details that match the permit
- The AHRI certificate showing the matched outdoor and indoor units and their ratings
- A dated invoice for the equipment and installation
- Proof the gas heat was capped, by photos or gas bills, for the gas-to-electric amount
Every Roomwise install carries a DC Department of Buildings mechanical permit, which this rebate requires. Read the DC permit guide for what the permit involves.
Deadlines for this program year
Submit within six months of purchase or by September 30, 2027, whichever comes first. DCSEU must approve the application by that date too.
That makes timing worth a thought for a job late in the program year. An install in August leaves only weeks, not six months, before the September cutoff. Our guide on when to apply for DC heat pump rebates walks through the yearly cycle.
Instant discount on the invoice
Where your system qualifies, the rebate can come off your Roomwise invoice as an instant discount, so you don’t wait for a check. The rebate is DCSEU’s, not ours, and DCSEU’s rules decide whether a system qualifies.
Other programs to know about
A few related programs sit alongside the equipment rebate. Each has its own rules.
- Panel and circuit rebates. DOEE lists DCSEU rebates of up to $2,000 for a panel heavy-up to 200 amps and $400 per circuit, up to three. The equipment form says it can’t be combined with other DCSEU or District offers, so ask DCSEU how the two interact before counting on both.
- Affordable Home Electrification. For income-qualified households, DCSEU runs a no-cost electrification program through its own assigned installers. If your household may qualify, apply there first.
- The federal tax credit. The IRS credit for heat pumps ended for equipment placed in service after 2025.
In DC, efficiency rebates come from DCSEU, funded through charges on Pepco and Washington Gas bills, so that’s the place to check rather than the utility.
How the rebate changes the math
A rebate lowers the price, but the job is still priced on the house. A standard single-zone install sits in Roomwise’s typical range of $3,000 to $6,000 before any rebate; your own price comes from the site visit and a written estimate.
