Furnace vs Boiler in Hill County, Montana
When a furnace makes sense
If your house already has ductwork, a furnace is the straightforward choice. It heats the air and sends it through the ducts you already have, and with 10 months of heating ahead of you each year, that ductwork earns its keep. Most homes in this region are set up this way.
When a boiler makes sense
If your home heats through radiators or in-floor pipes instead of ducts, a boiler fits what you already have. It runs about 5% cheaper here, which matters through winter nights averaging 8°F from December through February. It makes the most sense for a house without ductwork to convert.
