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.
How Cracked Heat Exchanger Be Dangerous?If your HVAC system 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 the heat exchanger are not functioning well or 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 over 400 Americans death every year due to CO poisoning. CO can be produced any time as your furnace burns fossil fuels. This gas is odorless and colorless, which make it hard for you to identify its presence in your home. We suggest installing a carbon monoxide detector and test them each season. Also, do not forget to change the device’ battery regularly to ensure proper operation.
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.
