Black mold near AC causing coughs; need professional testing?« Back to Previous Page

The black patches near your AC unit are likely mold, and they're a common cause of the persistent coughs your children are experiencing. In Dubai's humid climate, condensation from air conditioning units creates a perfect environment for mold growth, especially in enclosed spaces like behind furniture where air doesn't circulate.

Your immediate action should be to improve ventilation in that room. Move the wardrobe away from the wall and keep the bedroom door open to allow moisture to escape. Do not attempt to scrub the mold yourself, as this can release a large number of spores into the air and worsen the respiratory issues. For a temporary measure, you can lightly mist the area with a diluted white vinegar solution to help suppress the growth, but this is not a fix.

Given the symptoms and the visible growth, professional assessment is strongly recommended. The mold behind the wardrobe is just the visible sign; the root cause is likely excess moisture from the AC unit, possibly a clogged drain line or insufficient insulation, which needs to be identified and rectified. A certified inspector can perform air and surface sampling to identify the mold species and concentration levels, which is crucial for understanding the health risk and planning the correct remediation strategy. This is not just about cleaning what you see, but ensuring the hidden mold in the AC system and wall cavity is addressed to prevent recurrence and protect your family's health.
