Furnace vs Boiler in Kalamazoo County, Michigan
When a furnace makes sense
If your house already has ductwork, a furnace is the simpler path. It heats the air and pushes it through the ducts you have, and with winter nights here averaging 19°F for months at a stretch, that ductwork also carries air conditioning in summer without any extra piping. Most homes in this region are set up this way already.
When a boiler makes sense
If your home heats through radiators or pipes in the floor instead of ducts, a boiler is the one built for that. It runs about 5% cheaper than a furnace at Michigan gas prices, which matters over eight months of heating a year. It only heats, so if you want central air too, that has to come from somewhere else.
