Is hidden AC mold an urgent landlord issue?« Back to Previous Page

Yes, this is both urgent and a landlord issue. That size of hidden mold indicates a significant moisture problem, likely from condensation due to your AC running constantly against the high Dubai humidity. The persistent stuffiness you're experiencing is a common symptom of mold exposure.

You should alert your landlord immediately. In Dubai, landlords are generally responsible for maintaining the property's structure and essential systems, including the AC and addressing the moisture issues that lead to mold growth. Document the mold with clear photographs and send a written notification to your landlord or property management company, as this creates a formal record.

For a patch that large and concealed, professional remediation is strongly advised. DIY cleaning on porous surfaces like drywall is often ineffective and can disturb spores, spreading them further. A proper inspection will identify the moisture source—whether it's a faulty AC drain line, poor insulation causing condensation, or another leak—which must be fixed first to prevent rapid regrowth. A science-driven approach with post-remediation verification testing is the most reliable way to confirm the environment is safe.
