Furnace vs Boiler in Lancaster County, Pennsylvania
When a furnace makes sense
If your ducts are already in place and working, a furnace is the simpler path. It heats the air directly and gets your rooms up to temperature quickly once it kicks on, which matters on the nights here that drop to 24 degrees. That same ductwork can carry cooling later, if you ever add it.
When a boiler makes sense
If your home has radiators or in-floor piping instead of ductwork, a boiler works with what you already have rather than against it. It heats water instead of air, and that water keeps giving off heat after the burner shuts off. It also runs about 5% cheaper than a furnace at Pennsylvania gas prices, a difference worth having over the seven months a year you need heat here.
