Is black mold from AC leak an urgent landlord issue?« Back to Previous Page

That black mold is an urgent health and property issue requiring immediate action. The symptoms you describe—stuffy nose and headaches upon waking—are commonly associated with prolonged exposure to mold spores from a damp indoor environment. Given the leak has been ongoing for weeks, the visible patch is likely just the surface growth; the moisture has probably penetrated the carpet underlay and possibly the wall structure behind it.

In Dubai's climate, where high humidity and constant AC use create ideal conditions for mold, this situation will not resolve itself. You must notify your landlord in writing immediately. According to typical tenancy contract obligations in the UAE, the landlord is responsible for maintaining the property's structure and essential systems, which includes repairing the leaking AC unit and the resultant water damage. Mold remediation is a direct consequence of their failure to address the leak promptly.

Do not attempt to clean this yourself. Disturbing the mold without proper containment can aerosolize a high concentration of spores throughout your bedroom, potentially worsening your symptoms and contaminating other areas. A professional inspection is necessary to assess the full extent of the hidden damage and safely execute the remediation, which involves containing the area, removing contaminated materials like wet carpet and underlay, and using HEPA filtration to clean the air. The AC unit itself will also need a full internal inspection and cleaning by an HVAC specialist to prevent recurrence. Your first step is to document the mold and the leak with photos and formally notify your landlord.
