Furnace vs Boiler in Bossier Parish, Louisiana

When a furnace makes sense

If your ductwork is already in place, a furnace makes sense for a house like yours. Winters here are mild, with nighttime lows around 38°F and only about five months of heating needed, so you are not asking the furnace to work hard for long. It also gives you the option to add central air on the same ducts.

When a boiler makes sense

A boiler suits a home already set up with radiators or in-floor piping rather than ducts. It runs about 5% cheaper to operate here, and with a mild winter and a short heating season, that difference is worth something even if it is not dramatic. Keep in mind a boiler only heats, so you would need a separate system for cooling.
