A heat pump installation in the Seattle area costs about $10,218 on average, and most homeowners pay between $6,667 and $13,852, according to Angi's Seattle cost guide (regional estimate, updated July 2026). Utility rebates from PSE, Tacoma Power, Seattle City Light or Snohomish PUD can take a few hundred dollars to $4,000 off that price.

Heat pump installation cost in the Puget Sound area comes down to seven things: system size, system type, efficiency, the ductwork, the electrical panel, where the outdoor unit goes and permits.
Your heat pump rebate depends on your electric utility, your current heating system and, for some programs, your income. The federal 25C tax credit ended for equipment installed after December 31, 2025, so in 2026 utility rebates are the main incentive.
| Utility or program | Rebate | Key requirements |
|---|---|---|
| PSE: electric heat to heat pump | $1,500, plus a $2,400 Efficiency Boost for income-qualified customers | Single-family PSE electric customer heating with baseboard, wall heaters or an electric furnace. AHRI-certified ducted heat pump, or a variable-speed ductless system of at least 3/4 ton with a head in the main living area. No dual fuel. PSE Trade Ally or REP installer required. |
| PSE: heat pump upgrade | $1,500, plus $2,400 Efficiency Boost if income-qualified | Replacing a ducted all-electric heat pump that is out of its manufacturer warranty with a cold-climate model (COP at 5°F of 1.75 or higher). Ductless and dual fuel not eligible. Trade Ally or REP required. |
| PSE: natural gas to heat pump | Up to $4,000 | Income-qualified PSE customers switching from natural gas heat. Trade Ally or REP required. |
| Tacoma Power | $1,000 ducted air-source; $1,000 per ductless unit (up to 4 units; $650 at 5 or more); $2,000 for a variable-speed heat pump replacing electric forced air; $1,000 for variable-speed replacing non-electric heat | Minimum HSPF2 7.5 and SEER2 14.3. Participating contractor required. 0% loan up to $20,000 over 7 years, and an income-qualified deferred loan. |
| Seattle City Light | Instant discounts of $300, $400 or $600 by efficiency tier (units under 5.4 tons); $2,000 instant discount to replace oil heat | Discounts applied through participating distributors, so your installer passes them through. DIY installs not eligible. HomeWise help for income-qualified households. |
| Snohomish County PUD | $1,800 ducted conversion model; $2,500 ducted inverter-driven model | Electric primary heat. HSPF2 7.5 and SEER2 13.8 (conversion) or HSPF2 8.5 (inverter). Registered contractor; rebate taken off the invoice. |
| Energy Smart Eastside | Varies by program | For homes in participating Eastside cities; check the program for current amounts. |
| Washington HEAR program | Varies by local administrator | Households at or below 150% of area median income, through one of about 40 local administrators. |

A ductless mini-split is usually the lowest-cost option for one to three rooms, a ducted heat pump is usually the best value when a home already has good ductwork, and a dual fuel (hybrid) system pairs a heat pump with a gas furnace for homes that want to keep gas backup.
| System | Best for | Cost notes |
|---|---|---|
| Ducted heat pump | Homes with an existing forced-air furnace and sound ducts | Reuses ducts; price rises with size and efficiency |
| Ductless mini-split | Homes with baseboard or wall heaters, additions, bonus rooms | Priced per indoor head; see our Seattle mini-split cost guide |
| Dual fuel (hybrid) | Gas homes that want heat pump efficiency with furnace backup | Not eligible for PSE's electric-to-heat-pump or upgrade rebates |

A 2,000 square foot home in the Seattle area often needs about a 3-ton heat pump, which Angi's Seattle guide puts at $6,670 to $13,850 installed (regional estimate, July 2026). The right size comes from a load calculation, because insulation, windows and layout matter as much as floor area. Home Comfort Alliance runs a room-by-room load calculation (ACCA Manual J) on every installation.
The $5,000 rule is a rule of thumb: multiply the age of the system in years by the repair cost. If the result is more than $5,000, replacing usually makes more sense than repairing. A 12-year-old heat pump with a $500 repair scores 6,000, so replacement is worth pricing.
No. The federal Energy Efficient Home Improvement Credit (25C), which paid up to $2,000 for a heat pump, ended for equipment installed after December 31, 2025. In 2026 the savings come from utility rebates, Washington's HEAR program for income-qualified households and financing.
Yes. PSE pays its heat pump rebates only when the installer is a PSE Trade Ally or Recommended Energy Professional; DIY and out-of-network installs do not qualify. Home Comfort Alliance is a PSE Trade Ally for HVAC and water heaters.
Sometimes. A heat pump needs its own 240-volt circuit, and many 200-amp panels have room for it, while older 100-amp panels may need a load calculation or an upgrade. Our electricians check the panel during the estimate, and a panel upgrade adds to the total cost.
Yes. The new circuit needs an electrical permit from Washington L&I or from a city that runs its own electrical program, and many cities also require a mechanical permit. Angi lists about $130 for a typical Seattle permit. Home Comfort Alliance pulls the required permits for every installation.
For most homes, yes. Western Washington's mild, wet winters suit air-source heat pumps, one system heats and cools, and homes moving off electric baseboard or oil heat usually see the largest savings plus the biggest utility rebates.
