What’s the Danger of a Cracked Heat Exchanger?
A cracked heat exchanger is known to be a common furnace problem that often surprises homeowners during a routine furnace inspection. If an HVAC professional informs you that your furnace has a cracked heat exchanger, you need to act. Yet because this problem requires a full replacement of your furnace, you just might be tempted to ignore it. After all, the furnace is still operating, right? Yet a cracked heat exchanger can really put your family at serious risk. Before you ignore the problem, you need to understand the severe risk and how it could potentially impact your family.
What is a Heat Exchanger?
The heat exchanger is a component of the furnace that exchanges the heat between the return air from your home and the hot exhaust coming from the furnace combustion chamber. It heats the air before it returns to your home, keeping your family warm. Between these two air masses is a sheet of metal or metal tubing that delivers the exchange of heat but not the exchange of gasses. Therefore, the carbon monoxide and other gases stay out of the air in your home.
What Cracks Allow
A cracked heat exchanger will provide a place for dangerous carbon monoxide to escape the furnace and enter your home’s air. Even just a small crack could be large enough to allow gas to get out. While the CO levels may not be high enough to trigger a CO alarm, they can be high enough to cause headaches and other illness.
No homeowner would want to allow CO into their home day in and day out, yet this is exactly what happens when you keep running a furnace with a cracked heat exchanger.
