What’s the Danger of a Cracked Heat Exchanger?

A cracked heat exchanger can be a common furnace problem that could surprise some homeowners during a routine furnace inspection. If an HVAC professional tells you that your furnace has a cracked heat exchanger, you will need to take action. While this problem requires a full replacement of your furnace, you may be tempted to ignore it especially if your furnace is still functioning. A cracked heat exchanger, however, just might put your family at serious risk. Before you choose to ignore the problem, you need to fully understand this risk and how it could potentially impact your family.

What is a Heat Exchanger?

The heat exchanger is a piece of the furnace that exchanges the heat between the return air from your home and the hot exhaust coming in from the combustion chamber of the furnace. It’s what heats the air before it returns to your home, keeping you and your family warm and cozy. Between these two air masses is a sheet of metal or a type of metal tubing that allows the exchange of heat but not the exchange of gasses. This means that the carbon monoxide and other gases stay out of the air in your home.

What Cracks Allow

A cracked heat exchanger is a spot for dangerous carbon monoxide to leave the furnace and enter your home’s air. A slight crack can be large enough to allow gas to escape. While the CO levels may not be high enough to set off the CO alarm, they can be high enough to create headaches and other illness, which seems to have no explanation.

No homeowner would knowingly let CO into their home day in and day out, yet this is what is happening when you continue to operate a furnace with a cracked heat exchanger.
