A crack in the heat exchanger is bad news

A crack in the heat exchanger is bad news

Sometimes heat exchangers crack over time due to regular use.

A furnace that is more than 9 or 10 years old may develop cracks from expected wear and tear. Younger furnaces with cracked heat exchangers will often have other underlying problems that cause the issue. My sister found out that she had a cracked heat exchanger when the carbon monoxide detector in the basement started beeping. As soon as my sister heard the noise, she called the HVAC company to investigate the problem. My sister found out that the heat exchanger was cracked, even though her furnace was only a couple of years old. The HVAC technician told my sister that the problem was likely due to a dirty furnace filter or an obstructed duct. The guy suggested changing the filter more frequently and having a full home ductwork cleaning service performed. My sister ended up replacing the entire furnace when she found out about the heat exchanger. The HVAC company performed the ductwork cleaning service and only charged my sister half price, since she was already paying for the expensive furnace replacement as well. I hope the cleaning will help increase the lifetime of the furnace. Since I found out that my sister needed to replace the furnace, I have been very concerned about the health of my own heating device. I have a heat pump in my home, so at least I don’t have to worry about the same furnace problems that my sister worries about. Still, it’s important to stay ahead of maintenance and important service tasks.
