When you turn your furnace on for the first time each season in your Newnan, Georgia, home, you’ll likely notice a brief burning smell. This is caused by dust buildup on the system and should go away quickly. Other odors aren’t so innocent. The following furnace smells are key indicators of trouble. They should be addressed as quickly as possible to keep your home and family safe and warm this winter.


The smell of ozone is associated with burning electrical elements. You may have noticed this aroma before a coming thunderstorm as well. This type of aroma in the home can mean that your furnace has worn bearings or melted wire insulation. This, in turn, can cause the motor to seize up, and lead to a complete system failure. Don’t ignore this type of smell or attempt a DIY job. Call our technicians for a repair right away.


A sulfur or rotten egg smell indicates a gas leak in your home. This is something you should always be aware of if you have a gas furnace. Though the gas doesn’t have this aroma on its own, the unpleasant smell is added later to make it easier to detect should the gas escape. Gas is very flammable and hazardous to your health when inhaled. It can cause dizziness, nausea, headaches, and more. You should leave your home, call 911, and then your gas company.


Also described as a chemical aroma, a smell that makes you think of formaldehyde is bad news for your furnace. This may indicate a cracked heat exchanger. This can leak carbon monoxide into the home. If you have this type of smell in your home, contact our repair professionals immediately.

If you’re noticing strange furnace smells, this is an important warning sign that you should pay attention to. Give our technicians at Scott Walker Heating and Air a call at 770-282-5061 for a prompt heating repair.
