Regional cost guide
Oregon mini-split cost guide
Much of Oregon is climate zone 4C (west) / 5 (east). Electricity here runs 16.27 cents per kilowatt-hour, so a typical 12,000 BTU system costs about $485 a year to run. 2 rebate programs below can cut the installed price. Installed prices are mostly national — labor is the part that varies locally.

Typical Sizes And Installed Cost
Equipment, materials, electrical work and permits are priced the same everywhere. Only the labor line is adjusted to this state, which is why these ranges sit close to the national ones.
| Size | Equipment | DIY installed | Pro installed | Source |
|---|---|---|---|---|
| 9k BTU/h | $900 to $1,900 | $1,670 to $5,015 | $3,225 to $8,823 | National ranges, with labor adjusted to this state |
| 12k BTU/h | $1,000 to $2,400 | $1,820 to $5,665 | $3,586 to $9,896 | National ranges, with labor adjusted to this state |
| 18k BTU/h | $1,400 to $3,200 | $2,320 to $6,715 | $4,403 to $11,791 | National ranges, with labor adjusted to this state |
| 24k BTU/h | $1,800 to $4,200 | $2,870 to $8,015 | $5,270 to $13,937 | National ranges, with labor adjusted to this state |

Incentives
UTILITY_REBATE
Energy Trust of Oregon Residential Ductless Heat Pump Incentives
Applications open
Energy Trust publishes ductless heat pump incentive amounts effective for eligible installations on or after April 1, 2025 with no closure stated.
Covers mini-splits
Energy Trust names ductless heat pump incentives and the application card says Ductless Heat Pump.
Income tiers affect amount
Market-rate ductless heat pump incentives apply to eligible single-family and manufactured homes; Savings Within Reach and rental incentives remain at the higher listed amount and require the applicable Energy Trust qualification.
Effective for eligible installations on or after April 1, 2025, market-rate ductless heat pump incentive is $800 for site-built and manufactured homes, and Savings Within Reach and rental ductless heat pump incentive is $1,800.
- Equipment
- Ductless heat pumps in single-family and manufactured Oregon homes served by participating Energy Trust utilities, including Portland General Electric, Pacific Power, NW Natural, Cascade Natural Gas, and Avista.
- Efficiency
- Ductless heat pump must replace electric resistance heat and have HSPF of 9.0 or greater.
- Install
- Ductless heat pump must be installed by a qualified contractor. Residential incentive applications must be submitted within 60 days of work completion with required project documents such as contractor invoice and contractor consent form when the homeowner submits the application.
STATE_REBATE
Oregon Heat Pump Purchase Program
Applications open
ODOE says applications are open overall; existing owner-occupied funding is fully reserved, but rental property and new construction funding remains available.
Covers mini-splits
Oregon Department of Energy explicitly says eligible heat pumps include ducted, ductless, and split systems.
Up to $2,000 per eligible residence, reduced only if the full incentive plus other incentives would exceed 100% of the total purchase and installation price.
- Equipment
- Heat pumps for owner-occupied residences, residential tenancies, and new residential construction located in Oregon, including ducted, ductless, and split systems.
- Income
- No household income restriction is published. Existing owner-occupied home funding is fully reserved, while the July 2026 funding table shows rental property and new construction funding still available.
- Efficiency
- Heat pumps, including ducted, ductless, and split systems, must have HSPF2 of 8.1 or greater and SEER2 of 16 or more.
- Install
- An ODOE-approved contractor installs the heat pump, provides the incentive as an upfront cost reduction, and submits the incentive application after installation. Only one incentive is allowed per residence, and commercial, vacation, and transient occupancies are not eligible.
Federal credit timing and state-program caveats are covered in the mini-split rebates and tax credits guide.
Code Notes
- Oregon mechanical permit requirements are local. Portland provides a municipal data point where its residential mechanical permit page says heat pumps and mini-split systems are common projects that require a mechanical permit, and most mechanical equipment projects also need an electrical permit. Actual permit scope is decided by the local authority having jurisdiction.
- Portland is a municipal permit-cost data point for Oregon, not a statewide fee. Its July 10, 2026 mechanical fee schedule includes a heat pump row with site plan required in the one- and two-family dwelling fee table and a valuation schedule with a $167 minimum fee for $1 to $1,000 of mechanical valuation. Actual permit fees remain local.
