Furnace vs Boiler in Windsor County, Vermont

When a furnace makes sense

If your house already has ductwork, a furnace uses it and gets you heat fast on the cold nights here, when temperatures average 12°F. That ductwork also carries air conditioning in summer, which a boiler can't do. With nine months of heating needed most years, that matters.

When a boiler makes sense

If your home is set up with radiators or in-floor pipes instead of ducts, a boiler is the natural fit and it runs about 5% cheaper to heat with here than a furnace. It won't cool your home in summer, so it suits a house that either has no cooling system or handles that separately.
