AC leak causing mold and sickness in Dubai apartment?« Back to Previous Page

That black patch is almost certainly mold, and the timing of your husband's respiratory symptoms strongly suggests a connection. In Dubai's humid climate, AC condensation leaks are a primary cause of mold growth indoors, and the species commonly found in such environments can cause exactly those persistent allergic reactions.

You should absolutely speak with your landlord first. According to typical tenancy contracts and Dubai Municipality regulations, the landlord is generally responsible for maintaining the property's structure and fixed systems, which includes repairing the AC unit and its drainage to prevent the source of the moisture. Document the leak and the mold with clear photos and send a written notification to them requesting immediate repair and mold remediation.

For proper testing, a professional inspection is needed to assess the full extent, as visible growth often indicates a larger problem inside the wall or AC system. They use moisture meters and borescopes to see behind surfaces. A lab analysis of a tape lift or air sample can then identify the specific mold type, which is crucial for understanding the health implications and confirming the cleanup was successful.

The remediation process itself must address the source. A reputable company will first fix the AC leak, then isolate the contaminated area, remove the affected porous materials (like damaged drywall or insulation), HEPA-vacuum all surfaces, and finally treat the area with antimicrobial solutions. Simply spraying bleach or painting over it will not solve the problem. The goal is to return the spore count to normal outdoor levels, which should resolve the health symptoms.
