- What does a heat pump installation typically cost in Seattle?
- Heat pump installation in Seattle ranges from $4,000 to $8,000 for standard systems, depending on ductwork modifications, home size, and existing infrastructure. Dual-fuel systems (heat pump plus backup gas furnace) run $5,500 to $10,000. Mini-split heat pumps cost $2,000 to $5,000 per zone. Homes built in the 1970s often need additional prep work, which can increase final costs.
- Should I replace my old furnace with a heat pump, or repair it?
- If your furnace is over 15 years old and repair costs exceed $500, replacement with a heat pump usually makes financial sense. Seattle's mild winters mean heat pumps operate efficiently most of the year. Request a professional assessment to compare repair costs against a 10-year equipment lifespan and energy savings from a newer system.
- Why do Seattle homes need different heat pump sizing than other regions?
- Seattle's maritime climate means lower heating degree days than inland areas, so oversized systems waste energy and money. However, the city's older housing stock often has poor insulation, requiring slightly larger capacity than newer homes. A contractor should perform a Manual J load calculation to right-size your system for actual Seattle conditions.
