Furnace vs Boiler in Skagit County, Washington
When a furnace makes sense
If your home already has ductwork, a furnace is the simpler path. It heats the air and sends it through the ducts you already have, with nothing new to install underneath the floors or along the walls. Homes here need heat about 11 months a year, and a furnace is built for that kind of steady, long-season run time.
When a boiler makes sense
If your home heats through radiators or pipes in the floor rather than ducts, a boiler fits that setup directly. It also costs about 5% less to run here than a furnace, which adds up over a heating season that runs nearly 11 months, with winter nights averaging 30°F. That makes the boiler worth weighing seriously if your home has no ductwork to begin with.
