Is there a safety danger from a faulty heat exchanger?
No, the furnaces are safe and even the plaintiffs’ lawyers are not claiming that anyone has been injured. The furnaces are designed with many features to ensure safe operation, even if a problem were to occur. For example, if a hole were to develop in the heat exchanger, the combustion gases, including any carbon monoxide, would NOT leak from the hole into the circulating air. Instead, circulating air inside the home would be drawn into the hole and the combustion gases would be vented safely outside through the flue. Remember, for optimum performance, all furnaces, regardless of brand, should receive routine maintenance.
