The 3 Most Pervasive Problems in Heat Exchangers

Do you know what to look for to keep your heat exchanger in peak condition?

Tech looking at heat exchanger

If you want to get the most out of your HVAC unit, including the oh-so-important heat exchanger, a little knowledge can take you a long way. Unfortunately, it is very easy forget or overlook the important things when it comes to performing basic maintenance. If you just had a new furnace installed, you may think you don’t have to pay too much attention to the heat exchanger.

Here’s the thing: whether your unit is brand new or already has a few years under its tube bundles, making the time for regular check-ups can be the difference between smooth service or having to place a panicked call in to your service provider at an inconvenient time.

Some of the most common problems people experience with heat exchangers are:

  1. Deposit buildup, also called “fouling,” can cause your heat exchanger to use more fuel than necessary and can result in reduced heat transfer. The tube bundles and division plates can be affected by this buildup, resulting in poor performance. If not properly maintained, you can be left with costly repair bills in the future.
  2. Rust caused by condensation.
  3. Overheating, which results in excessive temperatures. If your furnace installation was recent and your fan speeds are not set correctly, your airflow will be inadequate from the very start.

Heat exchanger issues can be avoided with regular maintenance, and this is where an experienced HVAC company becomes your best option. Problems with heat exchangers can be very specific, and a professional will know what to look for, the proper maintenance program to follow, and will do their best to help you protect your investment.
