Furnace vs Boiler in Tippecanoe County, Indiana

When a furnace makes sense

If your house already has ductwork, a furnace is the straightforward choice. Most homes in this region are set up this way, and that ductwork can also carry air conditioning, which a boiler cannot. With winter nights averaging 21°F, you want a system that recovers fast, and a furnace heats a room quickly once it kicks on.

When a boiler makes sense

A boiler makes sense if your home already has radiators or in-floor pipes rather than ducts. Heating this way runs about 5% cheaper here, and with 8 months of heating season that adds up. The tradeoff is no ductwork means no central air, so you would need another way to cool the house in summer.
