Furnace vs Boiler in Livingston Parish, Louisiana

When a furnace makes sense

A furnace makes sense if your home already has ductwork in place, since it heats air and pushes it through the vents you have. Winters here are mild, with nights averaging around 42°F, so a furnace only has to run hard for about five months of the year. If you're not dealing with radiators or in-floor pipes already, a furnace is the simpler match for what your house has.

When a boiler makes sense

A boiler is worth a look if your home already has radiators or in-floor piping instead of ducts, since it heats water rather than air. It runs about 5% cheaper than a furnace here, which adds up over the five months a year your home needs heat. If you're not planning to add ductwork, a boiler works with what's already in your walls or floors.
