Furnace vs Boiler in Vanderburgh County, Indiana
When a furnace makes sense
If your house already has ductwork, a furnace is the straightforward choice. Most homes in this region were built with ducts already in place, so a furnace uses what your house already has. It also gives you the option to add central air later, since a furnace and air conditioner share the same ducts.
When a boiler makes sense
If your home heats through radiators or in-floor pipes instead of ducts, a boiler is the machine built for that setup. It runs about 5% cheaper to operate here than a furnace, which adds up over the seven months a year your home needs heat. Boiler heat also holds up well through the coldest nights, when winter lows average 27°F here.
