Furnace vs Boiler in Carver County, Minnesota
When a furnace makes sense
If your house already has ductwork, a furnace is the straightforward choice. It uses that ductwork to heat the whole house and it can pair with central air off the same ducts, which matters when you need heat eight months of the year and cooling the rest. Most homes in this region are set up this way already.
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. It runs about 5% cheaper to operate here, and with winter nights averaging 9°F from December through February, that difference adds up over a long heating season. It won't move cool air in summer, since a boiler only heats, so you'd need a separate way to cool the house.
