3 Signs Your Furnace Heat Exchanger is in Trouble
If you have a furnace in your home, it’s important to pay attention to its performance. A faulty furnace heat exchanger can lead to serious safety issues, costly repairs, or an inefficient furnace. While it can be difficult to detect a heat exchanger problem on your own, there are certain signs you can look out for that may indicate a problem. In this article, we’ll discuss the three main warning signs of a furnace heat exchanger gone bad.
1. Strange Odors
The first sign you should watch out for is an unusual odor coming from the furnace when it’s running. While most furnaces have a slight smell when they are first turned on, if you notice an unusual or strong odor coming from the furnace, it may be a sign that the heat exchanger is damaged. This odor may be a sign of carbon monoxide, which can be dangerous if not addressed quickly. It could signify that the heat exchanger has a crack or leak and is allowing dangerous gasses to escape into your home. In this case, it is crucial to seek a professional for HVAC repair in Atlanta immediately. They can inspect the furnace heat exchanger to determine if it has gone bad and get your home back to safety.
2. Unusual Sounds
Another sign of a furnace heat exchanger gone bad is hearing unusual sounds coming from your unit. If you hear loud noises, banging, popping, or rattling coming from the furnace when it is running, this could be a sign that something inside is not working properly. The heat exchanger may be suffering from excess heat that is causing it to expand and contract, creating strange sounds.
Or there could be other components of the furnace that are malfunctioning, such as the fan or the blower motor, which can also create strange sounds. By understanding what is a furnace tune-up and why you should get one, you can get your furnace repaired and back to working properly. This way, you can make sure your furnace heat exchanger is in good condition and free from any potential hazards.
3. Soot Build-Up
Soot is a black residue that forms when fuel does not burn completely. If you notice an excessive amount of soot on the outside of your furnace or around the vents, this could be a sign that something is wrong with the heat exchanger. This can happen when the heat exchanger is not burning the fuel efficiently, which can lead to more soot and smoke. You should also be aware of any discoloration on the walls near your furnace and any black residue around the unit.
These are the top three signs that your furnace heat exchanger may have gone bad. If you experience any of these issues, it is important to contact a professional HVAC technician to inspect and repair your furnace. This way, you can ensure that your furnace is running efficiently and safely without any of the dangers associated with a faulty heat exchanger. Thanks for reading.
