Residential Heat Exchanger Problems That Can Happen And Solutions For Them

One of the more important components of a residential heating system is the heat exchanger, which is basically a group of tubes that help move heat from one place to another in your system. It can face the following problems, but there are repair solutions for them.

Airflow Blockage

If there is a blockage of airflow around your heating system, then the heat exchanger can overheat. This leaves it more vulnerable to stress cracks. If you see that your heater isn't producing enough warm air that it should, you'll need to check components that can lead to blocked airflow. That includes your ductwork and air filter.

If you remove blockages causing restrictions in airflow, you're going to restore airflow around the heat exchanger and thus ensure it remains at the proper temperature range in the future. This will keep it working great for years.

Rust Development

Condensation is something that happens around the heat exchanger, which can result in excess moisture that leads to rust over time. This is a pretty easy problem to identify. If you find some rust on your furnace's heat exchanger, you need to treat it before this component has to be replaced entirely.

If you know where your furnace's heat exchanger is and can access it safely, you can treat rust yourself with vinegar and a scrubbing tool. If you don't know how to access this component, hire a repair contractor to treat the rust before it spreads to other parts of the heat exchanger.


If your heat exchanger is old enough, then it may have excessed so much wear and tear that cracks have actually formed. This is one of the more serious problems you could face with this component, and it's thus important to have a professional deal with cracks. 

Most of the time, cracked heat exchangers have to be replaced for safety reasons. However, if you hire a heat repair contractor, they can make sure and even help you find the right heater exchanger replacement that's sized perfectly for your current heating system.

In order to have a fully functional heater that blows warm air through the vents, the heat exchanger needs to be in good condition and performing great. If you spot problems with it, the best thing you can do is act quickly and take the right repair approaches from the beginning. For more information on heating repair, contact a professional near you.
