5 Symptoms Of A Bad Heat Exchanger

A heat exchanger is a crucial component in heating and cooling systems. They are responsible for transferring heat safely and effectively. A faulty heat exchanger can cause several issues, including overheating, energy loss, and system failure. 

To prevent these problems, the system must be well-maintained. In this article, you will learn more about the symptoms of a bad heat exchanger to help you spot issues and prevent them from becoming more significant.   


The Purpose of a Heat Exchanger 

 Bad Heat Exchanger: What is a Heat Exchanger?

Before diving in, one might ask, what is a heat exchanger? To put it simply, a heat exchanger is a mechanism in your furnace or heating system that quite literally exchanges the heat.

It takes heat from one substance such as water or oil, depending on the operation of your system, and exchanges it for the heat that is pushed out throughout the building. 

Heat exchangers play a pivotal role in the operation of the system and enhancing energy efficiency and reducing energy loss.  Moreover, heat exchangers are also helpful in reducing greenhouse gas emissions and supporting sustainability.  

5 Easy Tells That The Heat Exchanger Is Going Bad

Here are the 5 indications that you may have a bad heat exchanger:

Strange noises: Rattling, whistling, and other disturbing noises that continue over a period of time are obvious signs of a bad heat exchanger.

Change in flame color: Your furnace’s flame should be blue. If you see any other colors, such as yellow or orange, this can indicate a heat exchanger is going bad. 

Reduced efficiency: If your system is struggling to heat or cool your homes, this may indicate that your heat exchanger is going bad. Furthermore, if you notice a constant increase in your energy bill this may signal energy loss or leaks in your system. 

Corrosion: A heat exchanger has metal surfaces that can rust over time. This piece can corrode and cause it to not operate properly. 

Odd smell: Sometimes when a heat exchange is starting to go bad, it will give off a strong odor. 

If you start to notice any of these issues with your system or specifically your heat exchanger, it is always best to contact Spurk HVAC  and have it fixed right away.
