Could black mold in my AC be causing allergy symptoms?« Back to Previous Page

Yes, the black mold in your AC and behind the wardrobe is very likely the cause of your allergy-like symptoms. The damp, earthy smell is a classic indicator of microbial growth within the system. When the AC runs, it can aerosolize mold spores and fragments, distributing them throughout your apartment and leading to the stuffy nose and itchy eyes you're experiencing, especially overnight when exposure is prolonged.

Your situation in Jumeirah Village Circle is common here due to our climate. High humidity and constant AC use create ideal conditions for mold, particularly in areas with poor airflow like behind furniture. The condensation from AC units, if not properly drained, provides the moisture mold needs to thrive.

Your first step should be to stop the moisture source. Have a certified HVAC technician inspect the AC unit to identify and fix any drainage issues or internal water accumulation. Do not attempt to clean the internal AC components yourself, as improper cleaning can disperse more spores.

For the visible mold behind the wardrobe, you can carefully clean small patches (less than one square meter) with a detergent solution. Wear an N95 mask and gloves, and ensure the area is well-ventilated. However, since the problem is also in your AC—a central air system—a professional inspection is strongly recommended to assess the full extent. They can take surface and air samples to be analyzed in a microbiology lab, which identifies the specific type of mold and informs the correct remediation strategy, ensuring it is thoroughly addressed.
