AC mold on wall from leak: health risks and inspection?« Back to Previous Page

Yes, you should be concerned about both the leak and the visible mould. In Dubai's high humidity, a persistent AC leak creates the perfect damp environment for mould to proliferate rapidly, as you've seen. The black and green fuzzy growth indicates a significant colony, which can release spores into your bedroom's air.

Health risks vary by individual but commonly include nasal congestion, throat irritation, coughing, and worsened asthma or allergy symptoms. Infants, elderly family members, or anyone with respiratory conditions are more susceptible. The constant exposure from sleeping in that room is the primary concern.

For a proper inspection, do not disturb the area. A professional assessment is crucial here because the visible wall growth is likely just the surface issue; mould can penetrate drywall and insulation behind the wardrobe. A certified inspector will use moisture meters to map the full extent of water damage and take air and surface samples for lab analysis to identify the mould species and concentration levels. This data is essential for planning an effective remediation strategy, not just a superficial clean.

In the UAE, look for providers who conduct this kind of diagnostic testing and can provide a detailed report with verifiable lab results. While cleaning the AC unit is necessary, the wall and any affected building materials behind it must be addressed to resolve the problem permanently.
