Yes, Your Furnace Can Create Carbon Monoxide

Furnaces can cause carbon monoxide poisoning, but only in heating mode rather than air conditioning. The key is burning fuel. If you have a gas furnace, your unit has the potential to produce carbon monoxide.

Where Does Carbon Monoxide Come From?

Carbon monoxide happens when your furnace doesn’t burn gas completely. Normal combustion turns fuel into carbon dioxide and water vapor. But when the burners don’t work properly, not all of the gas turns into carbon dioxide and some of it becomes carbon monoxide.

The gas is colorless and odorless. When there is too much carbon monoxide in the air, you may experience symptoms such as dizziness, headache, weakness, nausea, shortness of breath, confusion, and blurred vision.

You can install a carbon monoxide detector in your home to detect any build-up of the gas before you experience symptoms. Like a smoke detector, you should change the batteries on the unit regularly.

Regular Furnace Service

Another way to prevent carbon monoxide in your home is regular furnace maintenance from Air Authority.
