Furnace vs Boiler in Clackamas County, Oregon
When a furnace makes sense
If your house already has ductwork, a furnace ties into what's there without any rework. Just over half the homes in this region are already set up this way. That same ductwork will carry air conditioning too, if you add it later.
When a boiler makes sense
If your home heats through radiators or in-floor pipes rather than ducts, a boiler fits what you already have. It also runs about 5% cheaper to operate here than a furnace, and with heat needed close to 10 months a year and winter nights averaging 32°F, that difference adds up.
