Why Does My Furnace Flue Need To Be Swept?
When combustion occurs, regardless of the type of fuel used, byproducts will result. Burning wood creates combustible creosote, which is what we’re focusing on removing during a traditional chimney sweeping appointment. In oil-burning furnaces, the byproducts created during combustion include carbon and sulfur deposits, usually referred to as oil soot. With gas furnaces, combustion results in minimal soot, but creates more moisture and acidic deposits, which can, over time, cause damage to flue liners.
Just like the chimney flue venting your fireplace or stove, your furnace flue needs regular maintenance in order to continue performing at its optimum level. Regular maintenance also helps extend the service life of your entire system, including the flue liner — a cleaner flue liner is a longer-lasting flue liner.
