If you’re like most homeowners, you probably don’t think too much about your furnace until something goes wrong. And while furnaces are typically reliable, they can occasionally cause problems, including carbon monoxide poisoning. So how can a furnace cause carbon monoxide? Let’s find out.

If you’re worried that your furnace might be causing carbon monoxide in your home, read on to learn everything you need to know. We’ll cover the symptoms of carbon monoxide poisoning, how to determine if your furnace is the source of the gas, and what steps you can take to remedy the situation.

What Is Carbon Monoxide and What Are the Dangers of Exposure to It

CO is a gas that has no smell or color. It’s produced whenever any fuel such as gasoline, oil, natural gas, or wood is burned. If your furnace isn’t functioning properly, it could produce high levels of carbon monoxide. 

This can be extremely dangerous because when you breathe in carbon monoxide, it replaces the oxygen in your blood. And it starves your vital organs of oxygen. This can lead to serious health problems including headaches, dizziness, nausea, and even death.

How Can a Furnace Cause Carbon Monoxide?

There are a few ways that your furnace can cause carbon monoxide to enter your home. One way is if there are cracks or holes in the heat exchanger. This happens due to the furnace expanding and contracting when heating up and cooling down over time. When this happens, it can create incomplete combustion, which will cause carbon monoxide to form. 

A furnace can cause carbon monoxide if it is not working properly. If your furnace is not venting properly, it can allow carbon monoxide to build up in your home.

This is what causes carbon monoxide from a furnace. You should have your furnace checked by a professional regularly to make sure it is working properly and to ensure there are no cracks in the heat exchanger.
