Furnace vs Boiler in Jefferson Parish, Louisiana
When a furnace makes sense
If you already have ductwork in place, a furnace is the simpler match. Winter nights here only average 47°F, and for four months of milder cold, a furnace heats the air quickly and gets out of the way the rest of the year. It also leaves the same ducts free to carry cooling in summer, which matters far more for this many months.
When a boiler makes sense
A boiler makes sense if your home already has radiators or in-floor piping instead of ducts. It runs about 5% cheaper to operate here, and with only about four months of real heating need, that gap stays modest either way. Choose it for the heat it gives off, not to save on a system you would otherwise have to add ductwork for.
