Furnace vs Boiler in Warren County, Ohio
When a furnace makes sense
If your home already has ductwork, a furnace is the natural fit. It pushes hot air through the house fast, which matters when nights average 25°F from December through February. Most homes in this region heat with a furnace already, and the same ducts can carry cooled air in summer if you add central air later.
When a boiler makes sense
A boiler makes sense if your home has radiators or in-floor piping rather than ducts. It costs about 5% less to run here at current gas prices, and that adds up over seven months of heating. The heat is steady too, without the temperature swings forced air can leave behind.
