How to safely remove hidden mold from AC in Dubai?« Back to Previous Page

Stop using that AC unit immediately and restrict access to the bedroom. The symptoms you describe—a persistent stuffy nose and cough—are classic reactions to prolonged mold exposure from a moisture source like an AC leak.

In Dubai’s climate, AC condensation leaks are a primary cause of hidden mold growth. The constant high humidity, combined with cool surfaces inside walls, creates an ideal environment for mold to flourish behind furniture and within wall cavities. Simply wiping visible patches is ineffective and can aerosolize spores, spreading the problem. For mold caused by an ongoing leak, the remediation process is specific: first, a certified professional must fix the AC leak at its source to stop the moisture. Then, the affected section of drywall, and likely the insulation behind it, needs to be carefully removed and disposed of, as mold roots deeply penetrate porous materials. The area must be HEPA-vacuumed and treated with antimicrobial solutions. Attempting this yourself without containment risks spreading spores to other parts of your home.

Given the location and the health symptoms, a professional inspection is strongly advised to assess the full extent of the growth inside the wall cavity. Reputable providers in the UAE should be able to conduct such an inspection and provide a scope of work, often backed by before-and-after testing from an independent lab to verify the environment has been returned to a safe, normal fungal ecology. This is the fastest way to resolve the root cause and ensure it is done safely.
