What’s Causing Your AC System to Produce Strange Odors?

AC System Causing Odors

Your air conditioning system can seem like a lifesaver on those scorching hot summer days in Edgewater, MD. However, malfunctions can happen with your air conditioner from time to time. Read on to learn what’s causing your AC system to produce strange odors and what you can do to mitigate them.


One of the most common smells that your air conditioning system may emit is that of garbage. This will typically happen the first time you start your AC system for the summer. The cause of this smell is likely a dead animal that crawled into it to seek warmth during the cold winter months.

Exhaust Fumes

One smell that may seem overly familiar is that of exhaust fumes. If you notice your air conditioner smells like the exhaust of your car, it’s likely there’s a fluid leak. The unit’s fluid is likely dripping onto a hot component of your air conditioning system and turning into fumes.

Dirty Laundry

If you’re smelling dirty laundry, it might not be from your clothes. It could be your AC system. More specifically, your condenser coil may be overgrown with bacterial growth, which is causing it to emit a nasty odor. Contacting an air conditioning professional is imperative to get your condenser coil clean and your air conditioner back to operating odorless.


If you notice a pungent burning smell coming from your air conditioning system, you should shut it off immediately. The most likely culprit is a part that has caught on fire or an electrical component that’s burning. It’s best to schedule an AC repair right away to handle the issue before turning your air conditioning system back on.
