Furnace vs Boiler in La Crosse County, Wisconsin

When a furnace makes sense

If your house already has ductwork, a furnace is the straightforward choice. It heats through those ducts, and most homes in this region are already set up that way. With eight months of heating ahead each year and nights down near 12°F, you want a system that matches what is already there.

When a boiler makes sense

A boiler makes sense if your home heats through radiators or in-floor pipes rather than ducts. It runs about 5% cheaper than a furnace here, which adds up over eight months of heating and winter nights averaging 12°F. If your house is already set up to heat that way, there is no reason to switch.
