how often do you all have your chimney swept?
(i have a combination oil burner / hot water heater, and a fireplace that I never use.)
Oil fired devices produce a lot of soot. The chimney should be cleaned every year, from top to bottom. Pull the stack pipe and you'll find a pile of debris at the base of the chimney.
The fired clay liners deteriorate at the top of the chimney first. Also check the connections between sections to make sure the mortar is completely filled in. This is especially important with the fireplace as embers can get out and hit framing, starting fires.
