Could AC mold be causing my coughing and sore throat?« Back to Previous Page

Yes, your symptoms are consistent with exposure to microbial growth from an AC unit. The constant moisture from a leak creates an ideal environment for mold and bacteria, particularly in Dubai's humid climate where ACs run year-round. The black speckles are a strong visual indicator, and the persistent cough, sore throat, and congestion you experience primarily in the bedroom point directly to the AC as the likely source.

The first step is to stop using that AC unit immediately to prevent further circulation of contaminants. Report the leak and visible growth to your building management immediately; Dubai Municipality regulations hold property owners responsible for maintaining HVAC systems to ensure tenant health and safety.

For a definitive answer, a professional inspection is advised. They can identify the extent of the growth inside the unit and the surrounding wall, which is often worse than what's visible. A proper assessment includes surface sampling around the vent and, more importantly, air sampling while the unit is running to measure the spore count you're breathing. This evidence is crucial for ensuring the remediation is done to a verifiable standard, not just a superficial cleaning.

Until it's resolved, improve ventilation in the room by opening windows when outdoor humidity is lower, typically in the early morning or evening. Consider using a portable HEPA air purifier in the bedroom to help reduce your exposure to airborne particles while you sleep.
