There are many important parts of your furnace and as the temperatures drop it’s important to learn how it works and how to fix it incase of any issues. A main component of a furnace is a heat exchanger, the place where your heating fuel combusts, creating the heat that warms the surface. When this reaction doesn’t happen properly, your home or office will not get warm. Many of the common issues in heat exchangers stem from cracks. If your exchanger is cracked, byproducts of the reaction will leak out into the air, such as carbon monoxide. Soot, rust, cracks or water on the floor by the furnace are all some signs that you may have an issue with your heat exchanger. The only way to know if you have true damage is to hire a professional HVAC worker who can properly appraise it. There are some helpful steps you can take to care for your heat exchanger, though, like changing your air filter frequently, keeping vents around your home open, and cleaning blocked vents quickly. Your best bet? Find your local HVAC technician to help care for your furnace so you can stay warm all Winter long!
