Where Does Carbon Monoxide Actually Come From?

Carbon monoxide (CO) is like that shady movie villain — lurking around when you least expect it.

Where does it come from?

But where does it come from in the first place? It’s produced during fuel-burning processes, and there are several culprits that could lead to a dangerous buildup in your home.

Common Sources of Carbon Monoxide

Here are a few common sources in homes:

  • Malfunctioning Gas Appliances: Any fuel-burning appliance that isn’t working or installed right can be a major source of CO.
  • Faulty Heating Systems: Regular upkeep of furnaces, gas ranges, gas dryers, water heaters, portable space heaters, fireplaces and wood-burning stoves is key.
  • Vehicles & Generators in Enclosed Spaces: Running these in an attached garage is a big no-no!
  • Blocked Chimneys or Flues: These can trap toxic gases inside your home, creating a dangerous situation. - Cracked or Loose Furnace Exchangers: This can allow CO to creep into your living space.
  • Back Drafting and Air Pressure Changes: This causes CO to flow back into your home instead of venting outside where it belongs.
  • Grilling Indoors: Operating a grill in an enclosed space is like giving CO a VIP pass to your home.
