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

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.
