Seattle Clean Heat Oil-to-Heat-Pump Rebate

Rebate amount

$2,000 - $6,000

Your qualifying range

$2,000 – $6,000

$2,000 instant rebate at any income, plus a $4,000 bonus for households at or under 150% of the 2026 King County median income ($6,000 together); the bonus applies to installations completed by May 30, 2027, while funds last. The participating contractor takes both off the invoice and submits the signed Homeowner Participation Form with a copy of the invoice to Gensco, the Mitsubishi Electric distributor that processes the program; there is no application or pre-approval. Eligible (the form's terms): the applicant owns the home and it is in the City of Seattle; it is an existing single-family residence of 1-4 units (single family, duplex, triplex or fourplex) or a townhouse, not multifamily and not new construction; its current primary heat is oil and the oil furnace is in working condition (a non-working oil furnace does not qualify, and homes not heated by oil are not eligible); and the new system is a qualified Mitsubishi Electric heat pump that meets the program's equipment requirements, installed by a participating contractor (Mitsubishi Electric Diamond Contractors on the City's list). After the install the homeowner decommissions the oil tank (fill in place or remove) per Seattle Fire Code section 5704.2.13. Bonus income limits (2026; the upper limit is 150% and the lower 80% of King County median, from HUD): 1 person $172,650; 2 $197,300; 3 $221,950; 4 $246,600; 5 $266,350; 6 $286,100; 7 $305,800; 8 $325,550. Income is disposable income per RCW 84.36.383(7) for everyone in the household in 2026 (a reasonable estimate is allowed), self-attested on the form, with proof on request. Seattle mailing addresses also cover unincorporated White Center, Boulevard Park and Skyway, and ZIPs 98133 and 98177 are mostly Shoreline; confirm the home is in the City of Seattle first.

Homes inside Seattle city limits only: the City of Seattle takes $2,000 off a qualifying Mitsubishi Electric heat pump that replaces working oil heat, installed by a Clean Heat participating contractor, plus a $4,000 bonus for households at or under 150% of King County median income (installations completed by May 30, 2027).

Guidance

The City of Seattle's Clean Heat Program takes $2,000 off a qualified Mitsubishi Electric heat pump that replaces working oil heat in a Seattle home, at any income, and another $4,000 for households at or under 150% of King County median income (installations completed by May 30, 2027). A participating contractor applies both on the invoice; there is no pre-approval.

Homeowner Tasks

Sign the Homeowner Participation Form
Complete the 2026 form, including household size and income if claiming the bonus, sign the terms and give it to the contractor.
Decommission the oil tank
Fill it in place or remove it per Seattle Fire Code section 5704.2.13.

Contractor Tasks

Apply the rebate on the invoice
Deduct $2,000, or $6,000 with the bonus, from the homeowner's invoice.
Submit the form to Gensco
Send the signed Homeowner Participation Form with a copy of the homeowner invoice to Gensco.

Oil heat only: the home's current primary heat must be oil and the oil furnace must work. Homes on gas, electric or a heat pump are not eligible.

Mitsubishi Electric heat pumps installed by a Clean Heat participating contractor (a Mitsubishi Electric Diamond Contractor on the City's list) only.

City of Seattle homes only: confirm the jurisdiction on the King County parcel record, since White Center, Boulevard Park and Skyway have Seattle mailing addresses.

Households under 80% of median income may instead get a free conversion, including tank decommissioning, through the Office of Housing's HomeWise program (Healthyhome@seattle.gov, 206-684-0244).

Qualification

Has income-qualified portion
The $4,000 bonus is for households at or under the upper income limit for their size (150% of the 2026 King County median income, HUD): 1 person $172,650; 2 $197,300; 3 $221,950; 4 $246,600; 5 $266,350; 6 $286,100; 7 $305,800; 8 $325,550. Self-attested on the Homeowner Participation Form (disposable income per RCW 84.36.383(7), everyone in the household, 2026), with proof on request. A household under the lower limit (80%: 1 person $81,700; 4 $116,650; 8 $154,000) may instead get a free heat pump, installation and tank decommissioning through the Office of Housing's HomeWise program (Healthyhome@seattle.gov, 206-684-0244), or may still claim the bonus.
Fuel switching required
Required: the electric heat pump must replace the home's current primary heat, oil, with the oil furnace in working condition; a home heated by natural gas, electricity, propane, wood or a heat pump is not eligible. The homeowner then decommissions the oil tank (fill in place or remove) per Seattle Fire Code section 5704.2.13.

Not required: energy star certified equipment · ahri matched pair · income-qualified · pre-approval required · permit required · contractor enrollment required

Stackability: The City's Seattle Area Heat Pump Rebates guide (April 2026) lists Seattle City Light's $300-$600 Home Energy Solutions heat pump discount, open to any existing fuel, alongside Clean Heat; neither program page states a restriction on combining them. The $4,000 bonus is itself funded by Washington's Home Electrification and Appliance Rebates (HEAR) program through the City. Puget Sound Energy's Efficiency Boost requires an existing gas furnace, so it does not apply to an oil-heated home.
