Could this AC mold be making my family sick?« Back to Previous Page

Yes, the mold behind your sofa is very likely contributing to your family's respiratory symptoms. The constant coughing and exacerbated allergies are classic reactions to mold spore exposure, especially in a confined space like an apartment where air is recirculated.

In Dubai's climate, this scenario is common. AC units create a cold surface, and when that cold air hits the humid room air, it causes condensation. This moisture accumulates on walls and in corners, particularly behind furniture that blocks airflow, creating a perfect breeding ground for mold. The dampness you feel confirms an active moisture issue. When the AC runs, it can indeed disturb and aerosolize these spores, distributing them throughout your living space.

For a situation this visible and with clear health impacts, a professional inspection is strongly recommended. They can identify the exact species of mold through lab analysis, which is important as some types are more problematic than others. More critically, they will locate the moisture source—whether it's a condensate drain line leak from the AC unit, poor insulation, or another building envelope issue—as solving that is the only way to prevent it from returning after a cleanup.

Immediate steps you can take include improving air circulation around that corner by moving the sofa permanently, using a dehumidifier to lower indoor humidity levels below 60%, and cleaning visible mold with a microfiber cloth and a solution of detergent and water (while wearing a mask). However, given the extent you've described, these are temporary measures until the root cause is professionally addressed.
