Today, we successfully replaced the heat exchanger in a furnace. We are grateful that our customer has carbon monoxide (CO) detectors installed in their residence, which potentially prevented a serious incident. During the replacement, we identified multiple rusted areas that were emitting carbon monoxide into the living space. This incident underscores the critical importance of CO detectors. We strongly recommend installing CO detectors if you don't already have them and replacing the batteries annually if you do. The life-saving role of CO detectors cannot be overstated.
