Facts to know about Trane heat exchanger crack in detail!

Trane heat exchanger crack: When a heat exchanger breaks in a house, it presents a serious problem for the homeowners. Leaving things unsolved for too long might have fatal consequences, so you shouldn’t try to handle it on your own. If you possess a heat exchanger, you need to read this to learn about the signs of a crack and the best technique to repair it. The heat exchanger keeps the fire running throughout winter and removes hazardous combustion byproducts including CO, water vapor, and caustic condensate. Heat exchangers keep fires burning. Here we will discuss more about Trane heat exchanger crack.

When do we talk about a heat exchanger?

Every gas heater has a heat exchanger inside of it. The heat exchanger in a furnace is essentially a bundle of metal strands that rub against one another. The combustion gases and flames quickly heat these coils. It transfers heat from the flue gas or exhaust fumes into your house while blocking the entry of harmful contaminants.

Alternative Heat Source:

At least one secondary heat exchanger is present in your house if your furnace has an efficiency rating of 90% or above. The flue gas undergoes a second heat exchange in the secondary heat exchanger, which causes condensation to occur. Once the combustion gas has gone through the first heat exchanger, it moves on to the secondary heat exchanger. The condensation of water vapor results in more heat being transmitted into the secondary heat exchanger. As a result, the furnace may function at a greater efficiency.

Cracked heat exchangers:

You may be wondering how severe a heat exchanger fracture really is and whether or not the issue warrants attention. A broken heat exchanger is an insidious and potentially fatal trap. If your gas furnace’s heat exchanger is cracked, it might leak deadly carbon monoxide gas and stop working properly. The next thing you know, the lights in your neighborhood have gone out when you were enjoying some downtime in your living room. The buck stops with this one factor, which has been overlooked for too long.

How can I discover heat exchanger cracks?

The fact that you won’t be able to determine if your heat exchanger is destroyed is one of the worst things that may happen. There are often no warning signs of a forming crack until it has spread to the point where it is almost certainly fatal. Your furnace may shut off if you’re lucky, but more often than not it will keep running, allowing carbon monoxide to seep into your house. No heat in winter, frequent flu-like symptoms, or a carbon monoxide alarm turning off is warning indications of a malfunctioning heat exchanger.

Detector of Carbon Monoxide Developed for Industrial Use:

At this point, you may be wondering how a professional CO detector is different from the one you have at home. While many homes do have carbon monoxide detectors, the great majority of such devices do not issue an alert until a dangerous concentration of CO is present. Unfortunately, chronic low-level exposure is not detectable with a store-bought CO detector due to its lack of sensitivity. Always remember that CO is harmful even when present in minute quantities.

Combustion Analysis Instrument:

The source of a CO leak is not usually the furnace; other appliances, such as the range or the water heater, might be the culprit. Therefore, a combustion analyzer is a very helpful tool. The flaws in the heat exchanger might cause combustion issues in your furnace. The efficiency of fuel-burning appliances may be determined by the combustion analyzer by measuring temperature and oxygen and carbon monoxide levels.

Camera with Infrared Light:

To conduct the visual inspection, a high-resolution infrared camera is placed inside the oven and moved about as needed. This technical breakthrough allows the expert to inspect the furnace for any corroded damage, holes, or fractures. The use of a camera to detect cracks or holes is more accurate than a professional’s eye assessment.

The heat exchanger has developed cracks:

As such, let’s not waste any more time and get straight to work. Why do heat exchangers often break and what causes that? The simplest kind of a heat exchanger is the periodic application of opposite temperatures to its contents. The metal in the part is designed to expand and contract in a continuous cycle, and this is exactly what is happening. It’s because of this that the heat exchanger eventually breaks down. Metal breaks under stress and wear and tear.


In the United States, hundreds of lives are lost annually due to carbon monoxide poisoning and faulty heat exchangers. In order to keep your family safe, you must routinely inspect and fix your HVAC system. Fortunately, the cost of a maintenance plan for an HVAC system in Phoenix is reasonable. Having a cracked heat exchanger increases the possibility that your furnace won’t work properly. More than that, it might lead to carbon monoxide poisoning and other health problems for your loved ones.


What is Trane heat exchanger crack?

A Trane heat exchanger crack may produce a dangerous carbon monoxide leak; therefore fixing it as soon as possible is crucial. It’s possible that a broken heat exchanger won’t be noticed until either your carbon monoxide alarm goes off or you discover that your home is suddenly cold.

Could a heat exchanger be repaired if it developed a crack?

We regret for the inconvenience. Immediately replace a cracked or rusty heat exchanger. Centrally located heat exchanger requires virtually full furnace disassembly. Assuming a $500 minimum cost, the highest cost may be $1000.
