What Is A Heat Exchanger?

The heat exchanger is vital in the heating and cooling process. It is where heat is transferred between fluids to heat or cool your home. If you have a heater, this component heats the air that is circulated via the venting system. The gas increases the temperature inside the heat exchanger so that the temperature of the air also increases. Naturally, if the heat exchanger malfunctions, your furnace’s operation is affected as well.

Symptoms Of A Cracked Heat Exchanger

• Flame Looks Different: The flame of a gas furnace is typically blue with a yellow tip. However, if it has turned predominantly yellow, then there might be a few issues. The burner might be dirty and needs to be cleaned. It could also be due to a cracked heat exchanger. Check the flame to see if it burns steadily. If you see it flickering, then it is likely experiencing an issue.

• Soot: Carbon buildup inside your furnace can result in soot. When the fuel does not burn cleanly and completely, it might be because of an improperly adjusted burner or a cracked heat exchanger.

• Corrosion And Cracks: Check the outer parts of your heating unit for any cracks and rust. Any physical problems with your heater’s external components could also point to damaged internal components.

• Unusual Smells: If you have a cracked heat exchanger, it will release an unpleasant formaldehyde-like smell. It can have repercussions on your health and cause severe headaches. Therefore, call a professional HVAC technician immediately to repair your system.

• Health Issues: A cracked heat exchanger can release carbon monoxide. It can cause serious health effects, such as nausea, disorientation, eye and nose irritation, and other flu-like symptoms. Prolonged exposure can be fatal, so have your cracked heat exchanger repaired immediately.

  Reasons Heat Exchangers Crack

  One of the most common causes of a cracked heat exchanger is an overheating furnace. This problem happens because of improper or insufficient airflow, which is a problem that frequently happens because of lack of maintenance. The furnace filters accumulate dust, dirt, and other debris over time. The coils and blowers can also get clogged. These issues block proper airflow, which is needed to maintain the internal temperature and absorb excess heat. Otherwise, the increased temperature can lead to a cracked heat exchanger.

  Other causes include worn out control valves. This issue results in extreme pressure changes that the heat exchanger cannot handle. Therefore, it is vital that your system is checked and maintained regularly to resolve all potential issues early.

  The Problem With A Cracked Heat Exchanger

  

  A damaged heat exchanger is more than just a hassle. It can pose a severe threat to your household’s safety. Many heating systems burn heating oil, natural gas, or propane. These fossil fuels generate fumes when burned. These fumes have soot, water vapor, carbon dioxide, and carbon monoxide. These gases can be harmful in large doses. When these leak into your home, you and your family can experience serious health problems.

  Solutions For A Cracked Heat Exchanger

  Never conduct a DIY furnace repair when you have a cracked heat exchanger. The solution can either be replacing this faulty component or installing a new replacement system. Both issues need to be considered carefully. A professional HVAC contractor will conduct a thorough inspection and test on your system so that they can recommend the best possible solution. An expert can also give you tips on how you can best care for your heating system.
