Furnace vs Boiler in Hamilton County, Indiana
When a furnace makes sense
If your home already has ductwork, a furnace is the straightforward choice. That's what most homes in this region are set up for, and those same ducts carry cool air in summer too. On nights that average 22°F from December through February, a furnace pushes warm air through the house quickly.
When a boiler makes sense
A boiler makes sense if your home already has radiators or in-floor pipes instead of ducts, or if you prefer the steadier heat of hot water over moving air. It costs about 5% less to run than a furnace here, which adds up over the 8 months a year this county needs heat. Just know a boiler only heats, so cooling would need a separate system.
