Can AC black mold cause sore throat and stuffy nose?« Back to Previous Page

Yes, black mold in your AC can absolutely cause the sore throats and stuffy noses you're experiencing. The damp, dark environment of an AC duct is an ideal breeding ground for mold, and when the unit runs, it aerosolizes spores and microbial fragments directly into your breathing space. This constant exposure is a common trigger for upper respiratory irritation, allergic reactions, and sinus congestion, particularly in a climate like Dubai's where we rely on AC year-round.

Given your symptoms and the visible growth, this warrants prompt attention. In a rental or building-owned system, your first step is to formally notify building management in writing, referencing the potential health hazard. Dubai Municipality has regulations concerning indoor environmental health and building maintenance that support tenant requests for remediation. They are typically responsible for the central system and ductwork.

Do not attempt to clean it yourself, as disturbing the mold can release a large number of spores. A professional inspection with surface or air sampling, analyzed by a microbiology lab, is the best course of action. This will identify the mold species and concentration, determining the exact risk level and required remediation scope. For a situation with persistent health symptoms and visible growth, addressing it urgently is recommended to prevent the issue from worsening.
