Carbon Monoxide Safety and Your Heating System in Georgia

Carbon monoxide is produced by incomplete combustion in gas furnaces, water heaters, and other appliances. In Georgia homes with gas heating, CO is a genuine safety concern every homeowner should understand.

How HVAC Systems Produce CO

A properly functioning gas furnace vents byproducts outside. CO becomes a risk when the heat exchanger cracks, the flue is blocked or disconnected, or dirty burners cause incomplete combustion.

The Cracked Heat Exchanger Risk

A cracked heat exchanger is the most serious HVAC-related CO risk. It separates combustion gases from the air you breathe. When cracked, CO can mix with heated air and circulate throughout your home.

Symptoms of CO Exposure

CO poisoning mimics flu without fever: headache, dizziness, weakness, nausea, confusion, shortness of breath. Symptoms that improve when you leave the home strongly suggest CO exposure. If suspected: leave immediately and call 911.

CO Detector Placement

Install on every level of the home, within 15 feet of sleeping areas, and near fuel-burning appliances. Choose detectors that display actual PPM readings. Test monthly and replace every 5 to 7 years.

Annual Heating Maintenance as Prevention

Annual heating maintenance that includes heat exchanger inspection is the primary prevention measure. The first time you run your furnace after months of inactivity is exactly when you want to know it is safe.
