However, the landlord’s argument about ventilation is a common one. While daily condensation on windows from extreme temperature differences is a tenant’s duty to manage, a persistent leak from an AC unit is a mechanical fault. The year-round operation of AC in Dubai’s climate is expected and should not, by itself, cause mold if the system is properly maintained and functional.

In this specific case, the leak is the primary cause, making the landlord responsible for repairing the AC unit and the resultant damage, including professional mold remediation. Mold behind a wardrobe is a serious concern as it indicates a sustained moisture issue and the spores can affect indoor air quality.

We strongly recommend you do not attempt to clean this yourself. Disturbing the mold can aerosolize spores. A professional inspection is crucial to determine the full extent of the contamination and to provide a legally valid report that can be presented to your landlord.
