AC leak causing mold on wall, who to call first?« Back to Previous Page

Call the AC technician first. The root cause is almost certainly a leaking condensate drain line or a poorly insulated AC duct running through that wall cavity. Until the moisture source is fixed, any mold cleaning will be temporary.

While waiting for the technician, move the wardrobe away from the wall to allow air circulation. Do not attempt to scrub the mold yourself, as this can aerosolize spores and worsen your children's respiratory symptoms. The damp wall and extensive growth on furniture indicate it has spread beyond the surface, likely into the wallboard itself.

After the AC leak is repaired and the area is dry, then call a mold assessment professional. In Dubai's climate, hidden mold in walls is a common issue due to high humidity and constant AC use. A proper assessment involves moisture meters and often an air or surface sample sent to an accredited lab to identify the species and concentration, which guides the safe remediation method. This two-step process—fix the water source, then address the biological contamination—is the most effective way to resolve the problem permanently.
