The best preventive measure for mold and mildew is to have a dehumidifier. This tool will absorb excess humidity and moisture in your room. So, it will be challenging for these molds to grow when the surrounding moisture is low. Lastly, it is better to call a repair service to check and assess what is happening to your air conditioner.

If you smelled the air from your air conditioning unit that is like stinky feet or dirty socks, the reason might be your coils are dirty. Also, it might smell like stagnant water in the air.

I advise you to ensure that your air conditioner is maintained well every one to two months. The professional cleaning team will pressure clean the parts of your air conditioning unit affected, so do not worry.
