Furnace vs Boiler in Brookings County, South Dakota
When a furnace makes sense
If your house already has ductwork, a furnace is the straightforward choice. Those same ducts can carry air conditioning too, which a boiler can't do. With nine months of heating a year and winter nights averaging 8°F, you want a system that matches what's already built into the house.
When a boiler makes sense
A boiler makes sense if your home is already set up with radiators or in-floor pipes instead of ducts. It runs about 5% cheaper to operate here than a furnace, which adds up over nine months of heating a year. The trade-off is no central ductwork to add air conditioning later without a separate system.
