Is AC mold causing our cough and stuffy heads?« Back to Previous Page

The symptoms you describe are classic signs of exposure to a microbial environment, and the combination of a leaking AC unit and black spots on the wall strongly points to mold. The high humidity in Dubai, combined with condensation from a faulty AC, creates an ideal breeding ground. Your symptoms resolving when you leave the bedroom is a significant indicator that the source is localized there.

The first step is to stop the moisture source. Have an AC technician repair the leak immediately; without addressing this, any cleaning is temporary. Do not attempt to clean the black spots yourself, as disturbing mold can release a high concentration of spores into your breathing air.

For a case with visible growth and health symptoms, a professional inspection is recommended to assess the extent, including inside the AC unit and the wall cavity. In the UAE, remediation should follow standards like the IICRC S520 to ensure it's contained and removed properly, not just wiped down. This is crucial for preventing recurrence and ensuring spores aren't spread throughout your home.

Until the AC is repaired and the area is professionally assessed, improving ventilation in the room can help. Keep the curtain open and the window slightly ajar when weather permits to reduce humidity levels.
