Why a heat pump makes sense in Western Washington

Washington winters are mild and wet rather than bitterly cold, which is the exact condition where a modern heat pump shines. A cold climate heat pump pulls heat from outdoor air even near freezing, so a single system can replace both your furnace and your air conditioner and run at efficiencies a gas furnace cannot touch.

State and utility incentives make the timing better than it has ever been. Washington has leaned hard into electrification, and Snohomish County PUD and Puget Sound Energy both offer heat pump rebates that can take thousands off the installed price, on top of the federal tax credit for qualifying high efficiency equipment. We handle the paperwork and size the system to qualify.

Our heat pump installation process

  1. A free in home assessment where we perform a load calculation, not a guess, so the system is sized to your square footage, insulation, and window exposure.
  2. A written proposal with equipment options, efficiency ratings, and every applicable rebate and tax credit spelled out.
  3. Professional removal of the old equipment and any refrigerant, recovered and disposed of to code.
  4. Installation of the outdoor unit, indoor air handler or coil, line set, and a smart thermostat, with electrical work coordinated and permitted.
  5. Commissioning: we verify refrigerant charge, airflow, and controls, then walk you through operation and warranty registration before we leave.

What is included

  • Manual J load calculation and correct equipment sizing
  • DOE certified installation crew
  • Permit filing and inspection coordination
  • Rebate and tax credit paperwork prepared for you
  • Smart thermostat setup and homeowner walkthrough
  • Ten year manufacturer parts warranty on qualifying systems

Heat Pump Installation pricing in Snohomish

Heat pump pricing depends on whether your home already has ductwork, the capacity you need, and the efficiency tier you choose. Rebates and the federal tax credit often bring the net cost well below the sticker figures below.

Service Typical installed price range
Ducted air source heat pump (whole home) $9,000 to $18,000 installed
High efficiency cold climate system $12,000 to $20,000 installed
Add on heat pump paired with existing furnace $7,500 to $13,000 installed
Typical rebate and federal tax credit value up to $2,000 to $4,000 back


These are typical ranges to help you plan, not a quote. Your price depends on your home and the equipment you choose. We provide a free, firm written estimate before any work begins, and financing is available on qualifying systems.

  • Historic Downtown Snohomish
  • Maltby

Will a heat pump keep my home warm on the coldest Snohomish nights?

Yes. Modern cold climate heat pumps are rated to heat efficiently well below freezing, which covers all but a handful of nights per year here. For homes that want extra insurance we can pair the heat pump with a backup heat strip or keep an existing furnace as a dual fuel system.
