Furnace vs Boiler in Calcasieu Parish, Louisiana
When a furnace makes sense
A furnace makes sense if your house already has ductwork, since that's what a furnace needs to move heat through your rooms. It also suits a place like this parish, where winter nights only average 44°F and heat is only needed about five months a year, because a furnace responds fast and doesn't need to stay warmed up between uses. If your ducts are older, a furnace can be paired with duct sealing or repair to keep that heat where you want it.
When a boiler makes sense
A boiler is worth a look if your home has radiators or in-floor piping instead of ducts, since that's the only way it delivers heat. It also runs about 5% cheaper than a furnace at Louisiana gas prices, which matters more in a house with no existing ductwork to install or repair. If you're building new or replacing a system that never had ducts, that's when a boiler earns its place.
