Mold growth in the air conditioner

Water droplets that should be evaporated gather in your vehicle when the atmosphere has high water vapor content. In addition, mold growth results from leaves or plant materials combined with the excess moisture that has not been drained. This can be due to a faulty drainage system.

Hence, the mold creates new cells in their growth process. As the cells die off and decompose, they produce alcohol, which gives off the vinegar smell. In addition, the organisms yield further condensation and moisture, which causes the issue to spread beyond control.

Clogged condensate pan

This car component was designed to catch condensation as humid air flows through the evaporator coil. When water droplets trickle down from the air handler, it causes an intense smell of vinegar.

The buildup of natural decaying materials

Natural materials such as plants or animal matter can find their way into your air conditioning vents. When these accumulate, they decompose and ferment, forming alcohol with the aid of water droplets made in the air conditioning system. This originates from the vinegar smell you later identify.

In its operating state, the air conditioner blows out the vinegar smell resident in it into your vehicle, creating discomfort.

Old air filters
