Personal Experience

How do I get the sour smell out of my car aircon?

Living in a warm climate, my car’s AC is my closest friend. Unfortunately, recently it started to smell like vinegar when I was running the AC. Apparently, this is a common problem and there are several possible causes.

The most common cause of a vinegar smell coming from the air conditioner is the build-up of mold within the car’s evaporator. The evaporator is made up of tiny tubes called fins, where the refrigerant flows, and moisture accumulates in those tubes. This creates a moist environment where mildew and mold can form and cause a distinct smell of vinegar when you turn on the AC.

I took my car to a nearby car repair shop where I was told that I needed to flush the evaporator completely, since it was clogged with mold and mildew. Indeed, after the full system flush, the smell went away and my AC was working just like before.
