Is landlord responsible for cleaning moldy AC vents?« Back to Previous Page

The black growth around your AC vents is almost certainly microbial growth, and the persistent humidity in Bur Dubai provides the ideal environment for it. Your children's coughing is a common reaction to the spores being circulated into the room.

Under Dubai Law No. 26 of 2007 (Amended by Law No. 19 of 2017), landlords are responsible for maintaining the structural parts and main systems of the property, which includes the central AC system and its ductwork. Since the mold is on the vents and likely within the ducts, this falls under the landlord's obligation to provide a habitable property. You should formally notify them in writing, requesting a professional inspection and remediation.

However, for immediate health concerns, document the issue with photos and dates. You can arrange for a professional indoor environmental assessment; a credible inspection includes air and surface sampling sent to an accredited microbiology lab to identify the specific type of mold and its concentration. This data provides concrete evidence of the air quality issue if you need to escalate with your landlord or the Dubai Land Department.

While waiting for a resolution, you can wipe visible surface mold from the vent covers with a microfiber cloth and a solution of diluted white vinegar, but this is only a temporary measure. The core of the problem is inside the ductwork, which requires specialized cleaning equipment. Improving ventilation by opening windows when outdoor humidity is lower (typically early morning) can also help reduce moisture buildup temporarily.
