Is AC leak mold causing my husband's illness?« Back to Previous Page

The black mold from your AC leak is highly likely to be the cause of your husband's persistent respiratory symptoms. Constant moisture from a leaking unit creates an ideal environment for mold growth, and the spores released into the air commonly cause nasal congestion, coughing, and throat irritation, especially in individuals with sensitivities.

In Dubai's climate, where we rely on AC year-round, such leaks are a frequent source of indoor mold due to condensation and high humidity levels. The wall cavity behind the wardrobe is a critical concern, as hidden mold can amplify the problem significantly.

Responsibility for remediation typically depends on the leak's source. The building management is generally responsible for fixing the AC unit itself and any damage to the main building structure or chiller lines. As the tenant, you are usually responsible for addressing the mold growth on your personal property and within the apartment's interior, such as the wall surface.

Your first step is to formally notify the building management or owner in writing about the AC leak, as it is the source of the problem. They must repair the unit to stop the moisture intrusion. For the existing mold, given its extent and the health symptoms, a professional inspection is strongly advised to assess the contamination fully. Remediation involves containing the area, safely removing the affected materials, and thoroughly cleaning to prevent spores from spreading. Simply wiping it is insufficient and can make the situation worse. Verifying the cleanup with post-remediation testing is the best way to ensure the environment is safe.
