Is AC mold causing my family's cough?« Back to Previous Page

It is very possible that AC mold is contributing to your family's persistent cough, especially given the recent humidity and your discovery in the wardrobe. The high humidity in Dubai creates ideal conditions for mold growth, and older AC units are common sources as they can develop condensation issues and harbor spores that then circulate throughout your home.

The fastest and safest approach is to engage a professional indoor environmental consultant for an inspection. Do not attempt to clean the visible mold on the jackets yourself, as this can aerosolize the spores and worsen the problem. A proper assessment involves more than just looking at vents; it includes using moisture meters to find hidden dampness and, most critically, air and surface sampling to be analyzed by an accredited microbiology lab. This lab analysis is the only way to definitively identify the mold type and concentration, which determines the health risk and required remediation protocol.

For remediation, ensure any company you contact follows the IICRC S520 standard for mold remediation, which includes containment of the affected area and use of HEPA filtration to prevent cross-contamination. The entire AC system, including hidden ductwork, will need a thorough cleaning with specialized equipment. In the interim, while you arrange for inspection, keep the bedroom door closed, avoid using the AC in that room if possible, and consider using a standalone HEPA air purifier to help reduce spore levels in the air. Resolving this requires identifying the moisture source, professionally removing the contamination, and verifying with post-remediation testing that the environment is safe.
