Get the Facts on this Heater Carbon Monoxide Threat
As a furnace gets older, there are many different kinds of problems it could have. While most furnace repairs are often relatively minor and don’t pose a big concern, a furnace with a cracked heat exchanger is a dangerous problem that must be addressed right away.
The reason why is simple. A crack in your heat exchanger could let gas escape from your heating system. That could cause carbon monoxide to seep into your home.
How Big is the Carbon Monoxide Risk?
While a cracked heat exchanger puts you at risk for carbon monoxide, it doesn’t always mean that CO is leaking into your home. It is possible that your heat exchanger could have a crack and is NOT leaking carbon monoxide.
This is obviously not a gamble you should make.
Because there is the potential that carbon monoxide could be leaking from a cracked heat exchanger, you should immediately take steps to get it safely handled by a professional HVAC technician.
Since a cracked heat exchanger poses such a potentially significant hazard, you should turn your furnace off and not turn it on again until the issue is completely fixed. Sometimes a professional who detects a crack will shut down your furnace in such a manner so that it cannot be turned back on to ensure the safety of everyone in the home.
Causes for Cracks in a Heat Exchanger
The leading cause for an exchanger to get a crack is from the unit overheating.
If a furnace does not get sufficient airflow, the heat exchanger can get too hot and crack under the pressure of continually expanding and contracting.
So, if the issue is with airflow, it’s good to understand how airflow can get restricted.
It may sound odd, but simply having a dirty air filter is often why you do not have proper airflow from your home’s HVAC system. That is why having a clean furnace filter is the most important maintenance you need to do on your home’s heating system. This task is essential in preventing the likelihood of such dangerous problems as cracked heat exchangers.
Other issues, like a furnace that is too large or too small for your home, can also cause an exchanger to crack. A professional furnace installer will be able to identify exactly what size and type of furnace is right to safely and adequately heat your home.
Does this Problem Always Require a Repair?
Absolutely. A cracked heat exchanger is always a risk for dangerous, even deadly, carbon monoxide poisoning. The solution for fixing it is often to have your heat exchanger replaced. However, you may want to get your entire furnace replaced, especially if your furnace is more than ten years old.
How To Know if a Heat Exchanger is Cracked
By taking a visual inspection of your furnace, you may be able to see a crack. But there are other signs, including:
Cracks or corrosion on other parts of the heating system
Soot build-up inside of the furnace
Wet floor near the furnace (not from condensation)
A cracked heat exchanger is not always easy to see. Often a crack cannot be detected by a simple visible inspection. Special tools and devices may need to be used to detect cracks that a homeowner cannot see on their own.
