AC leak caused mold, how to safely remove it?« Back to Previous Page

That black mould is a serious concern, especially with the symptoms you're describing. A leaky AC unit creates a constant moisture source, and Dubai's high humidity provides the perfect environment for rapid mould growth, often within 24-48 hours.

The fastest and safest approach depends on the size. For a small patch (under one square foot), you can carefully clean it yourself with a diluted vinegar or hydrogen peroxide solution, wearing an N95 mask and gloves. Isolate the area and ensure it is completely dry afterwards. However, given the location behind a wardrobe—indicating hidden spread—and the presence of a persistent leak, this is likely a larger issue.

A professional inspection is strongly advised. They will identify the full extent of the growth, stop the moisture source by repairing the AC drain line, and safely contain the area during remediation to prevent spores from spreading to other parts of your home. For health safety, especially with infants or anyone with asthma, do not attempt a large cleanup yourself. Verifiable post-remediation testing from an independent lab is the only way to confirm the air quality is safe.
