The right system depends on the house
Greater Seattle's housing stock spans a century — and the honest HVAC answer for a plaster-walled Tudor is completely different from a Sammamish two-story's. Find your house; get its real options.
Pre-1940
Craftsman / Tudor / Foursquare
Plaster walls, no ducts (or gravity-furnace relics), maybe an oil tank
Usual answer: Ductless multi-zone heat pump
See the full guidance
1950s–1970s
Rambler / Split-Level
One story or split, electric baseboard or aging ducts, oil or early gas
Usual answer: Ducted heat pump (with duct sealing) — or ductless if baseboard-heated
See the full guidance
1980s–2000s
Suburban Two-Story
Gas furnace + full ductwork, upstairs too hot, downstairs too cold
Usual answer: Ducted heat pump (or dual-fuel with your furnace)
See the full guidance
1990s–today
Townhome / Condo
Small mechanical closet, shared walls, maybe HOA rules
Usual answer: Compact ducted heat pump (e.g. Daikin FIT) or slim ductless
See the full guidance
Seattle's backyard boom
ADU / DADU / Garage Conversion
Backyard cottage, basement apartment, or converted garage
Usual answer: Single-zone ductless heat pump
See the full guidance
Any home
One Problem Room
Bonus room over the garage, converted attic, basement office
Usual answer: Single-zone ductless head for that room
