Mold under AC in villa: DIY or call landlord?« Back to Previous Page

This is likely condensation-related mold from your AC unit, a common issue in Dubai's humid climate where AC systems run year-round. The damp smell and carpet mold suggest excess moisture is escaping the unit's drain system or insulation.

For a small patch (under one square meter), you can DIY with care. Wear an N95 mask and gloves. Mix a solution of one part white vinegar to four parts water, lightly scrub the visible mold on the wall and carpet corner, then dry the area completely with a fan. Do not use bleach, as it doesn't prevent regrowth and can worsen indoor air quality.

However, the critical step is identifying and stopping the moisture source. The problem is almost certainly a blocked condensate drain line, a cracked drain pan, or poor insulation around the AC ducting inside the wall. This is a mechanical fix beyond most tenants.

Given this is a structural issue with the AC system in a villa, you should notify your landlord or property management immediately. Under typical Dubai rental agreements, the landlord is responsible for maintaining the property's structural integrity and fixed appliances like AC units. They need to send an HVAC technician to repair the leak at its source. Without this fix, the mold will return quickly, even after cleaning.

While waiting for the repair, increase ventilation in the room and keep the area as dry as possible. For extensive growth or if you experience persistent musty odors or health symptoms, a professional mold inspection can identify the full scope and recommend remediation.
