Could our AC mold be causing our respiratory issues?« Back to Previous Page

Yes, the mold from your AC leak is very likely causing your respiratory issues. The constant stuffy nose and persistent cough are classic symptoms of mold exposure, often referred to as "sick building syndrome." The leak has created a consistently damp environment in that closet, which is an ideal breeding ground for mold spores that then circulate every time the AC unit turns on.

In Dubai's climate, where we rely on AC year-round, these enclosed, damp spaces are a common problem. The high humidity and condensation from AC units provide the perfect moisture source for mold to thrive behind walls and under floors.

You should call a professional mold inspection company first, not a general handyman. A proper inspector will use tools like moisture meters and thermal imaging cameras to find the full extent of the water damage hidden behind the wall, which is almost certainly larger than the visible patch. They should then take air and surface samples for analysis at an accredited microbiology lab to identify the specific mold species. This lab report is crucial, as it confirms the type and concentration of spores, which informs the necessary remediation protocol.

Do not attempt to clean this yourself with bleach, as improper disturbance can aerosolize a high concentration of spores throughout your apartment. The primary fix is to stop the leak at its source—have an HVAC technician repair the AC unit immediately to prevent further moisture intrusion. Only after the leak is fixed should remediation of the affected building materials begin.
