Urgent: AC causing damp smell and black mold?« Back to Previous Page

Yes, this requires immediate attention and you should notify your landlord this week. The damp smell and visible black spots indicate active mold growth, which is common here due to our high humidity and constant AC use. The AC unit itself is likely a source of moisture from condensation, spreading spores and that damp smell throughout your bedroom.

Under Dubai rental regulations (RERA), landlords are responsible for maintaining the property to ensure it is habitable, which includes addressing mold issues caused by building or AC system defects. Document the mold with photos and send a written notification to your landlord. This creates a formal record of the issue.

Do not attempt to clean it yourself with bleach, as this often fails to address the root moisture problem and can disturb toxic spores. The moisture source must be identified and fixed—often a clogged AC drain line, poor insulation causing condensation, or a leak. A professional inspection can pinpoint the cause, which is critical for effective remediation. In many cases, the AC system will also require a specialized deep clean by HVAC technicians to stop the spread of spores.

Given the current humidity levels, waiting will only allow the mold to spread further, potentially affecting your health and belongings.
