Cracked Heat Exchanger

Furnace Problems & Carbon Monoxide Threat

There are many different problems a furnace could have, especially older ones. Most heating system repairs homeowners encounter are relatively minor and don’t pose a significant concern. However, a furnace with a cracked heat exchanger is a potentially dangerous problem.

A crack in your heat exchanger could let carbon monoxide escape from your system, which means carbon monoxide could seep into your home. That is why this is a problem that needs to be addressed right away.

What is the Carbon Monoxide Risk?

A cracked heat exchanger does put you at risk for carbon monoxide, but it does not always mean that CO is being leaked into your home. A heat exchanger can have a crack, but it is NOT causing a carbon monoxide leak.

This is not a chance you should take. Because a cracked heat exchanger can always leak carbon monoxide, you should immediately have a professional HVAC technician address it.

This is a potential hazard that you should not turn your furnace on again until it is fixed. Here in Michigan, it is required by law that an HVAC professional who detects a crack will shut your furnace down. That way, we can ensure it cannot be turned on again, risking the safety of everyone in the home.

Leading Causes of a Cracked Heat Exchanger

The main cause is from overheating. If a furnace does not get enough airflow, the heat exchanger can get too hot and crack under the pressure of constantly expanding and contracting.

How does airflow get restricted? A dirty air filter is often the reason. That is why having a clean furnace filter is essential maintenance for your heating system. This basic task is vital in preventing such problems as cracked heat exchangers. However, other issues, like a furnace that is too large or too small for your home, can cause a heat exchanger to crack.Heat exchanger

Does this Crack Always Require Repair?

Yes. A cracked heat exchanger is always a risk for carbon monoxide poisoning. The repair is to have your heat exchanger replaced. You may also choose to get your entire furnace replaced, especially if it is more than ten years old.

How To Tell if a Heat Exchanger is Cracked

You may be able to see the crack yourself during a visual inspection of your furnace. Sometimes, it is not easy to spot.

Other signs to look for:

  • Cracks on other parts of the heating system
  • Soot build-up inside of the furnace
  • Irregular or rolling burner flames

Often, a crack cannot be detected with a simple visual inspection by the homeowner. Special tools and devices may be needed to detect cracks that non-professionals cannot see independently.
