Who is responsible for black mold by the AC unit?« Back to Previous Page

Black mold by an AC unit is typically the landlord's responsibility to remediate, as it stems from a building or system defect. Dubai's high humidity and constant AC use create perfect conditions for condensation, which leads to mold if there's inadequate insulation, a clogged drain line, or a leak in the AC unit itself. Simply wiping it with bleach is a temporary fix because it doesn't address the underlying moisture source.

Your landlord's claim that your AC setting is the cause is likely incorrect. While very low temperatures can increase condensation, the primary issue is almost always a fault in the system or the building envelope that allows moisture to accumulate. The responsibility for structural and system repairs lies with the property owner.

For a definitive answer, a professional inspection is needed to identify the exact moisture source—whether it's a leaking AC drain pan, poor wall insulation, or a crack in the external wall. This diagnostic report is crucial evidence. Under standard Dubai tenancy contracts, landlords are responsible for maintaining the property's structure and essential services, which includes a functioning AC system that doesn't cause damage.

I recommend formally requesting your landlord arrange for an inspection. If they refuse, you can file a complaint with the Dubai Rental Dispute Center (RDC). For your family's health, especially with children coughing, do not attempt to remediate this yourself. Proper mold removal requires containing the area, removing contaminated materials, and fixing the water problem—a process best handled by specialists to ensure it doesn't recur.
