AC smell and black spots: urgent for landlord?« Back to Previous Page

Based on the symptoms you've described—a damp, earthy smell from the AC and visible black spots on a wall—this is a strong indication of active mold growth. In the context of Dubai's high humidity and the condensation issues inherent to year-round air conditioning use, this situation should be considered urgent.

The smell is often the first sign of microbial volatile organic compounds (MVOCs) being released by mold colonies, which are likely thriving in the damp environment created by your AC system, possibly due to a clogged condensate drain line or inadequate insulation. The black spots behind the wardrobe confirm a visible infestation. This area is a classic trouble spot due to poor air circulation, which allows condensation to accumulate unseen.

Under UAE tenancy law, landlords are responsible for maintaining the property's structure and essential services, including the AC system and addressing issues like moisture intrusion that lead to mold. This constitutes a maintenance issue that affects habitability.

Do not delay. You should notify your landlord in writing immediately, detailing the issue and requesting a professional mold inspection and remediation. Attempting to clean it yourself or waiting could allow the colony to spread into the wall cavity or HVAC system, significantly increasing the scope and cost of remediation.

For a definitive assessment and to ensure the remediation is handled correctly to Dubai Municipality standards, I recommend a certified professional inspection. Our team at Saniservice can perform a comprehensive assessment, including moisture mapping and air quality testing, to identify the source and extent of the contamination.
