Signs of a Cracked Heat Exchanger

Signs That Your Heat Exchanger Is Cracked

Regardless of the type of heating system installed in your home, it is important to keep the interiors of your home warm during the cold winter season. If you want to make sure your heating system stays in good condition, it should be serviced at least once a year. Without maintenance, your system’s heat exchanger could become damaged or cracked. When you hire our maintenance services, we work hard to identify a problem with your heat exchanger before it becomes a serious problem. If your unit’s heat exchanger is cracked, there are definite signs to look out for.

Primary Symptoms of a Cracked Heat Exchanger

The heat exchanger of your HVAC unit is an important aspect of the heating and cooling process. This is the process of transferring heat from one liquid to another to heat or cool your home. If the heat exchanger fails or cracks, the efficiency of your furnace or HVAC system will likely be adversely affected.

A clear sign of a cracked heat exchanger in a gas oven is that the flame looks different. If your gas oven is working properly, the flame should be blue with a bright yellow tip. However, if the flame has mostly turned yellow, there could be several problems with your stove. The burner may be dirty and needs to be cleaned. A more serious problem is a cracked heat exchanger. If you experience this problem, a Wingate heating, cooling, and plumbing technician can offer repair or replacement services.

You should also look out for soot as it is a sign that the fuel is not burning properly. This sign indicates that the heat exchanger has cracked or the burner has been incorrectly adjusted.

You should check the exterior of your heater for signs of rust or cracking. If there is a physical problem with the external components of the system, it may be a sign that the internal components have also been damaged.

If you notice a strange smell of formaldehyde in your home, it indicates that your heat exchanger has a crack. If this problem persists, headaches and other health problems can occur. Cracked heat exchangers can potentially release carbon monoxide into the air. If the problem is not addressed, symptoms such as disorientation, nausea, and eye irritation can result, as well as more serious and even fatal health problems.

Why Heat Exchangers Crack

Heat Exchanger

Probably the most common cause of heat exchanger cracks is overheating of the furnace. This problem is caused by poor airflow that occurs when the system is not regularly maintained.

Dirt, dust, and other types of debris accumulate in your furnace filters. Over time, fans and coils could become clogged. These issues can block the airflow needed to maintain a certain indoor temperature and properly absorb excess heat. Otherwise, cracks may occur at higher temperatures.

Another cause of a cracked heat exchanger is a worn control valve, which causes high pressure changes that a heat exchanger cannot handle. Regular maintenance can solve this problem from the start.

Importance of Repairing a Cracked Heat Exchanger

A damaged heat exchanger can pose a risk to the health and safety of your home. Many types of heating systems burn oil, propane, and natural gas. These fuels produce smoke during the combustion process. Vapors that enter the air contain carbon monoxide, carbon dioxide, soot and water vapor, which can be harmful in large doses.

If you suspect your heat exchanger has a crack, you can purchase a new HVAC system or have the failed component replaced. Consider these two options carefully before making your decision. One of our HVAC experts can perform an inspection of your system to determine if a cracked heat exchanger is the cause of your problems.
