Furnace vs Boiler in Allen 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 in place, and a furnace uses them to heat every room and can pair with central air off the same system. With winter nights here averaging 21°F, you want a system that already fits the house it's going into.
When a boiler makes sense
A boiler makes sense if your home heats through radiators or in-floor pipes rather than ducts. It runs about 5% cheaper than a furnace here, which adds up over the 8 months a year this county needs heat. It won't move air for central air conditioning, so that has to work for how your home is already set up.
