Furnace vs Boiler in Blount County, Tennessee
When a furnace makes sense
A furnace is the right call if you want your air ducts doing double duty, since the same system can carry cooling in the summer once you add central air. Winter nights here average 31°F, and a furnace responds fast, pushing warm air through the house as soon as it fires. If your home already has ductwork in place, a furnace makes the most of it.
When a boiler makes sense
A boiler suits a home that already has radiators or in-floor piping instead of ducts, since it heats water rather than air and needs that kind of delivery system to work. It runs about 5% cheaper here than a furnace, which adds up over the 7 months a year this county needs heat. If your house has no ductwork and no plans for central air, a boiler is worth a serious look.
