Heat Pumps in Washington: Pros, Cons & Cost (2026)

1) Heating + cooling in one system – A heat pump works as both a heater and an air conditioner, which is a smart upgrade for many homes without AC.
2) Lower monthly energy bills (in many homes) – Many homeowners reduce energy usage compared to electric baseboards or older heating systems (results depend on insulation, ductwork, and sizing).
3) Comfortable, even heat – Modern heat pumps provide steady heating and better temperature control, especially with a smart thermostat.
4) Cleaner option (no gas combustion inside the home) – No fuel is burned indoors, which can improve air quality and safety.
5) Better home value & long-term upgrade – A properly installed heat pump is one of the best upgrades for long-term comfort and efficiency.

1) Higher upfront cost – Heat pump installation is usually more expensive than a basic furnace replacement, especially if ductwork or electrical upgrades are needed.
2) Installation quality matters a lot – The #1 reason people dislike heat pumps is poor installation (wrong sizing, bad airflow, incorrect refrigerant charge, no duct sealing, poor drainage). A heat pump is only as good as the contractor installing it.
3) Older homes may need ductwork or insulation improvements – Leaky or undersized ducts can reduce performance and comfort.

1) System size & home layout – Square footage, room count, and layout affect sizing and labor.
2) Ductwork condition (if ducted) – Older ducts may need sealing, new returns, resizing supply runs, or airflow balancing.
3) Electrical panel & circuit needs – Some homes require a new breaker, wiring upgrades, or disconnect changes.
4) Brand & efficiency (SEER2 / HSPF2) – Higher efficiency costs more upfront but may lower long-term operating cost.
5) Permits & code requirements – Permits and inspections may be required depending on the city and job type.
