AC leak causing black patches and sickness: mold?« Back to Previous Page

Based on the symptoms and conditions you've described, there is a very high probability you are dealing with a mold issue. The black patches around the AC vent are a classic visual indicator of mold growth, and your symptoms—stuffy nose, itchy eyes, and persistent morning headaches—are common allergic reactions to mold spores being circulated by the air conditioning system.

In Dubai's climate, where high humidity and constant AC use are the norm, AC units are a prime location for mold. The leaking water provides the necessary moisture, while the dark, cool interior of the ductwork offers an ideal breeding ground. When the AC operates, it aerosolizes these spores, distributing them throughout the room where you spend hours breathing them in while you sleep.

This is a serious health concern that requires immediate action. Under UAE tenancy laws, landlords are responsible for maintaining the property's essential systems, including air conditioning, to a habitable standard. A persistent leak and resulting mold growth constitute a breach of this obligation.

You should absolutely push your landlord for a professional inspection and remediation. Do not attempt to clean this yourself, as improper disturbance can cause a significant release of spores, exacerbating your health issues and contaminating other areas. A certified professional will conduct air and surface sampling to identify the mold type and concentration, perform a thorough inspection of the AC unit and ductwork, and execute a controlled remediation plan following industry standards.
