Furnace vs Boiler in Harrison County, Mississippi
When a furnace makes sense
A furnace fits a home with ductwork already in place for a heat pump or central air conditioner. Winters here only average 42°F, and heat is only needed about 5 months of the year, so you want equipment that responds fast on the cold nights and shuts off the rest of the year without a second thought. If your ducts are in good shape, a furnace will use them without any changes.
When a boiler makes sense
A boiler is worth a look if your home already has radiators or in-floor pipes instead of ducts, since a boiler heats water rather than air and needs that kind of distribution to work. It also runs about 5% cheaper than a furnace at Mississippi gas prices, which matters more if you are replacing a boiler that is already there than if you are starting from ducts. With only about 5 months of heating a year, that saving stays modest either way.

Furnace wins in Harrison County.
Most homes here already have the ductwork a furnace needs, since the area was mostly built up by 1994, so a furnace is the easier fit.
If your home already has radiators or in-floor pipes instead of ductwork, a boiler is still the better choice.
