Why Does My Aircon Smell Like Feet and What to Do

The infamous "feet smell" of your aircon - it's a problem many of us have faced at some point. The culprit behind this unpleasant odor is usually a buildup of bacteria and mold in the aircon's filter.

This can happen when the aircon's filter is not cleaned regularly, allowing moisture to accumulate and create an ideal breeding ground for bacteria and mold.

The smell can also be caused by the aircon's drainage system, which can become clogged with debris and bacteria, leading to a musty odor.

In some cases, the aircon's smell can be a sign of a more serious problem, such as a refrigerant leak or a faulty condenser coil.
