Why Does My AC Smell?

You may notice an odd smell in your home that seems to get worse whenever your air conditioning system is on. Identifying what it smells like can go a long way toward figuring out what the issue is. Here are some smells that you may notice and what they mean.

Smelly Feet

The scent of smelly feet means that your air conditioning system is either dirty or clogged. This bad smell is coming from water that has pooled because it cannot drain properly. This means that your AC system is in need of a thorough cleaning.

Gunpowder

This smell indicates that your outdoor AC unit has had either its motor or circuit board short out. You’ll need to have the unit serviced by a professional HVAC contractor.

J's HVAC Unlimited of Mount Airy, NC, diagnoses and resolves problems with your air conditioning system. Our certified technicians can handle any make and model.

Rotten Eggs

This smell is usually the result of a dead animal in your HVAC system. Birds and rodents can get into your air ducts, die and start to decompose. A professional can remove the animal remains from your ducts, which will remove the smell.

Exhaust Fumes

Since air conditioners are powered by electricity, people don’t realize the smell of exhaust fumes are coming from them. There are fluids in an AC system’s motor and other parts that can leak, causing this smell. An HVAC technician can solve this issue.

Mold and Mildew

This smell means you have mold or mildew growing in or near your AC system. This is caused by an excess of moisture when water isn’t able to drain properly. HVAC technicians are trained to deal with this issue, resulting in your home having better air quality.
