Furnace vs Boiler in Lafayette Parish, Louisiana
When a furnace makes sense
If your ductwork is already in place, a furnace is the simpler path. Winters here are mild, with nights averaging 44°F and heat only needed about five months a year, so you don't need the steady, even warmth a boiler is known for. A furnace also gives you the option to add central air on the same ducts.
When a boiler makes sense
If your home already has radiators or in-floor piping and no ductwork, a boiler is the right fit rather than something to add for its own sake. It runs about 5% cheaper to heat with than a furnace at Louisiana gas prices, which matters more the more months you're running it. Just know it heats only, so cooling would need a separate system.
