Furnace vs Boiler in Franklin County, Missouri
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 a furnace can also carry central air conditioning through those same ducts. With winter nights averaging 24°F, you want a system that can push heat fast, and a furnace does that well.
When a boiler makes sense
A boiler makes sense if your home is already piped for one, heating through radiators or pipes in the floor instead of ducts. It runs about 5% cheaper here than a furnace, and it gives you a steadier, even heat through the cold months. Without ductwork already in place, though, you would need a separate system for cooling.
