This article will tell everything you need to understand about a cracked heat exchanger and its dangers to you and your family. Continue reading below.

What is a Heat Exchanger?


Simply put, a heat exchanger in your furnace is a component that allows the heat to move from one element to another without direct interaction. They just cross paths next to each other and then exchange heat.

Your heat exchanger is the one exchanging the heat between your return air and hot exhaust. Between these air masses, you can see metal tubing that allows effective heat exchange and prevents hazardous gas emissions, keeping the carbon monoxide (CO) and other gasses at bay.

When the heat exchanger gets damaged, it is advised to call the pros for immediate furnace repair in Searcy, AR.

How a Cracked Heat Exchanger Causes Danger


If your furnace works properly and all of its components are in good working condition, dangerous gasses can be prevented from entering your home. But if its components like heat exchangers are not functioning well or have been damaged, the CO gas might come into your space and pose a great danger to your health.

The Centers for Disease Control and Prevention reported that over 400 Americans die every year due to CO poisoning. CO can be produced any time as your furnace burns fossil fuels. This gas is odorless and colorless, making it hard for you to identify its presence in your home.

It is suggested to install a carbon monoxide detector and test them each season. Also, don't forget to change the device's battery regularly to ensure proper operation. Ask your local HVAC contractor for assistance when you need inspection or furnace repair in Searcy, AR.

What Are the Signs That You Need Heat Exchanger Repair?


These are the signs that you may need to have a heat exchanger repair:

  • The flame is not steady, and it is yellow, not blue.
  • The components of your furnace are corroded.
  • There is a presence of black carbon build-up or soot on your furnace.
  • The heat exchanger has cracks.
  • You and your family can experience the symptoms of carbon monoxide poisoning such as headache, blurred vision, dizziness, weakness, vomiting, and breathing difficulty.

When you notice these signs, bring in the pros for furnace repair in Searcy, AR. They have the tools and experience to solve the problem and restore your unit's function.

How Regular Furnace Maintenance  Prevents Heat Exchanger Issues


Regular furnace maintenance is the best way to ensure that your heat exchanger works at its best. Today's most furnaces are built with a single-wall (or one-layer) metal heat exchanger.

This type of unit is known for having problems because the thin metal can get quite corroded over time due to condensate forming on it, causing corrosion and pitting.

The more regular furnace maintenance you do, the less likely it becomes that these types of issues arise in the first place or become bad enough to affect furnace performance or efficiency.
