Urgent: AC mold causing child's cough, how to clean safely?« Back to Previous Page

The black spots are almost certainly mold, and the persistent cough is a common symptom of mold exposure, especially in children. With an active leak, this requires immediate professional intervention.

First, stop using that AC unit and isolate the closet. Keep the door closed and avoid disturbing the moldy clothes, as this releases more spores. Do not attempt to clean it yourself with bleach or store-bought sprays; improper methods can aerosolize the spores and worsen the contamination.

The fastest and safest approach is a two-part professional response. You need an HVAC technician to repair the leak and address the condensation issue, which is a chronic problem in Dubai's humid climate. Simultaneously, you need a certified mold remediation specialist to handle the contamination. They will contain the area, use HEPA filtration to clean the air, and properly dispose of or clean the affected materials. For health concerns like this, a company with its own microbiology lab can test to identify the mold species, which informs the safest, most effective removal protocol.

Until professionals arrive, increase ventilation in the bedroom by opening windows if outdoor humidity is low and use a standalone HEPA air purifier. Wash any unaffected clothes in hot water. With children present, err on the side of caution; their respiratory systems are more vulnerable. The Dubai Municipality has guidelines for indoor air quality, and reputable remediators adhere to these standards. Request a post-remediation verification test to confirm the space is safe before using it again.
