Stepping into your car, are you met with an unpleasant smell from the AC? That’s not only annoying, but it can also be a sign of serious problems. In this article, you’ll learn all about the causes of unpleasant odors from your car’s AC and how to effectively eliminate them.
Why Does My Car AC Smell?
A musty, moldy smell from the AC usually points to mold or mildew growth in the ventilation system. Condensation forming on the AC evaporator creates a damp environment that provides ideal conditions for mold and bacteria.
In addition to mold, other causes can be responsible for unpleasant smells:
- Clogged Cabin Air Filter: A dirty cabin air filter can not only cause unpleasant odors, but also reduce the AC’s performance.
- Refrigerant Leaks: Leaking refrigerant can spread a sweet, chemical smell throughout the vehicle interior.
- Contaminants in the Ventilation System: Dust, dirt, and leaves can accumulate in the ventilation system over time and lead to unpleasant odors.
