Furnace vs Boiler in Prince George's County, Maryland
When a furnace makes sense
If your home already has ductwork, a furnace is the simpler path, since it can use those same ducts for central air, which a boiler cannot run. It heats homes through the ducts you likely already have rather than radiators or in-floor pipes. With winter nights averaging 28°F and about 7 months of heating needed, a furnace paired with existing ductwork is a straightforward fit.
When a boiler makes sense
If your home heats through radiators or in-floor pipes rather than ducts, a boiler fits without adding ductwork. It also runs about 5% cheaper than a furnace at Maryland prices, which adds up over 7 months of heating and nights near 28°F. Keep in mind a boiler cannot supply central air, so if you want cooling from the same system, that is worth weighing.

Furnace wins in Prince George's County.
Just under half the homes in this region already heat with a furnace, and the county's older housing stock tends to have the ductwork in place.
If your home already has radiators or in-floor pipes instead of ductwork, a boiler is still the better choice.
