Can My Car’s Air Conditioning Make Me Ill?

Can my car's air conditioning make me ill?

In a word – yes. It may seem unlikely but there is strong evidence that your car’s air conditioning can actually make you ill. The air that is pushed into your car’s cabin may seem cool and fresh but there can be a lot wrong with it. And often that problem is mould.

Mould can grow on the air conditioning’s evaporator deep inside the system, where it is dark and wet. The evaporator cools the air that comes out of the air vents inside the cabin. The evaporator gets wet in the process and provides a surface on which mould can develop.

How Your Air Conditioning Can Make You Ill

The air that travels through the evaporator into the cabin will pass any mould that has developed. The bacteria there can make you ill. In some extreme cases the mould can lead to an infectious pneumonia – however this is extremely rare. If you do have mould growing in your air conditioning you’re more likely to experience minor respiratory issues, such as a slight tightening of the chest. Other people may cough or sneeze.


How Do I Know If There Is Mould In My Air Conditioning?

If there is a strange smell coming out of your air conditioning vents, then it is most likely due to a build up of mould. There other causes, such as a build up of residue from cigarettes, however in most cases this is due to mould. If this is the case, the best course of action is to get your car air conditioning professionally cleaned, as this will help to kill the bacteria.

The best way you can protect yourself from mould build up, is to keep you car AC regularly serviced. Ensuring that you’re AC filters are renewed regularly will help ensure that dangerous levels of mould don’t build up.
