Who is responsible for mold in rental AC ducts?« Back to Previous Page

Landlord responsibility for AC mold hinges on whether the issue stems from neglect or tenant misuse. In Dubai, landlords must provide a habitable property, which includes maintaining the core AC system and ductwork. The tenant is typically responsible for routine filter changes.

Your situation in JLT is complex. The landlord's claim that filter neglect caused the extensive mold is a common defense. However, the climate here is a major factor; year-round AC use and high humidity cause significant condensation inside ducts, which is the primary cause of mold growth, not just a dirty filter. If the system wasn't properly sanitized between tenants, this is almost certainly a pre-existing condition that has worsened. The fact you just renewed your contract six months ago in Discovery Gardens strengthens your case that the issue was latent.

For a case this severe with health symptoms, a professional inspection is critical to determine the source and extent. The resulting lab report is your key evidence. It can prove if the mold type and colony size indicate long-term growth, contradicting the landlord's claim.

Politely insist the landlord arrange and pay for the inspection, citing your right to a healthy living environment under Dubai rental law. If they refuse, you may need to file a case with the Rental Dispute Center (RDC), where the inspector's report would be pivotal. Do not attempt to clean this yourself; disturbing extensive mold can exacerbate the problem and your health issues.
