Learn How to Prevent and Remove Mold in Your Air Conditioning System

Mold can particularly thrive in areas that are dark and damp. One such area is the air conditioning system.

When the AC unit is turned on, mold growth can disperse the spores into the air, which you then breathe in.

So, it is crucial to identify and remove any mold growth in the AC unit and prevent it from recurring in the future.

Air conditioners are susceptible to mold buildup, because the cooling coils create condensation that leads to moisture. Besides, air conditioners and ductwork also provide a dark space where mold can grow.

So if you have an AC unit, pay attention to these signs:

The AC unit emits a musty odor when it is turned on.
Fungal growth can be observed near the air vents, drip pans, and evaporator coils.
Anyone in your household is experiencing throat, nose, eyes, or skin irritation when the AC is running.

How to remove the mold growth

Homeowners are advised against cleaning AC units themselves. However, if you decide to do so, you should take these 7 steps:

Ensure your safety by wearing rubber gloves, a face mask, and goggles.
Refer to the owner’s manual and open the unit, vacuum the interior, and remove the filter.
Remove visible mold and debris from the filter and wash it under running water.
Wipe down all surfaces of the unit using soapy water and allow it to dry.
Use a commercial AC cleaner and a mold inhibitor, such as vinegar and water.
Discard any contaminated cloth in a tied plastic bag.
Reinstall the filter, reassemble the unit, and reinstall it.

It is important to remember that the safest way to remove mold is by hiring a mold removal specialist.
