AC leak causing mold and sickness, what to do?« Back to Previous Page

Yes, get a professional inspection. The combination of an AC leak, visible black discoloration, and persistent respiratory symptoms strongly suggests a mold issue that needs to be addressed at its source.

In Dubai's climate, AC units are a primary source of condensation and, if leaking, create a constant moisture source perfect for mold growth inside walls. The substance you see is likely a microbial colony, but only a lab culture can confirm if it's the Stachybotrys species often called "black mold" or another type. Your husband's symptoms are a common reaction to prolonged exposure to mold spores circulating from the AC unit and the damp wall cavity.

For your health, see a general practitioner first to address the immediate symptoms; mention the potential mold exposure. For your home, a professional inspection is the critical next step. They will identify the exact moisture source from the AC, assess the extent of the hidden damage within the wall, and take air/surface samples for lab analysis to identify the species. This evidence is crucial for building management to take corrective action, as per Dubai Municipality's health and safety standards for residential buildings. Do not attempt to clean this yourself, as disturbing it can aerosolize a high concentration of spores.

The remediation process will involve stopping the AC leak, properly drying the affected wall cavity, and removing the contaminated materials.
