From The Fairbanks Daily News-Miner, Saturday, December 25, 2010:
Charlie Whitaker has cleaned chimneys of boilers, furnaces, fireplaces and wood stoves through his company, A Chimney Sweep, for 27 years.
“Boilers and furnaces can malfunction at a moment’s notice,” he said.
While he did not inspect the chimney of Alyson and Mike Padilla, which leaked carbon monoxide into their home last week, he offered some common advice for maintaining and detecting problems in oil-fired boilers and furnaces. He also explained the common causes of soot in these systems.
The National Fire Protection Association recommends you have your chimneys inspected and tuned (if they require it) annually.
