AC leak causing mold and health issues: first step?« Back to Previous Page

Yes, your symptoms and the black spots are almost certainly connected to the AC leak. Dubai's high humidity and constant AC use create ideal conditions for mold growth when moisture is present. The persistent stuffy nose and itchy eyes are classic indicators of mold exposure.

Your first step is to stop the moisture source. Have a certified HVAC technician inspect and repair the AC unit's drain line or condensation pan immediately—this is the most common cause of such leaks. Do not attempt to clean the mold yourself with bleach, as this can aerosolize spores and worsen the problem.

For a situation that has persisted for months and is causing health effects, a professional inspection is strongly recommended. They can assess the extent of the growth, which is often far greater inside the wall or unit than what is visible on the surface. In the UAE, remediation should follow standards like the IICRC S520 for proper containment and removal to prevent cross-contamination.

Until help arrives, improve ventilation in the closet area and consider using a dehumidifier. Keep the area dry and avoid disturbing the mold to prevent further spore release.
