Could mold in our AC be causing our cough and allergies?« Back to Previous Page

My kids have been coughing non-stop for the past month and my own allergies are worse than ever. We've lived in our Jumeirah villa for two years and just noticed a bunch of black spots spreading along the wall behind the wardrobe in the master bedroom, which is right where the AC unit is. Could this mold be the reason we're all feeling so sick?

Yes, the mold behind your wardrobe is very likely contributing to your family's persistent cough and allergies. In Dubai's climate, AC units are a common source of indoor mold because they produce condensation in their drain pans and ducts, creating a constant source of moisture. The black spots on the wall indicate a significant growth, and its proximity to the AC unit suggests the system is actively dispersing spores into the air you breathe.

The high humidity here, combined with year-round AC use, creates ideal conditions for mold. The most common types found in UAE homes, like Cladosporium and Aspergillus, are known respiratory irritants. Continuous exposure can cause exactly the symptoms you describe: chronic coughing, worsened allergies, and congestion, particularly in children.

You should arrange for a professional indoor environmental inspection. A proper assessment involves more than a visual check; it includes air and surface sampling to identify the specific mold species and spore concentration levels. This is crucial for determining the right remediation strategy. In serious cases like this, where there is visible growth and health impacts, Dubai Municipality guidelines recommend engaging certified professionals to ensure safe and complete removal to prevent recurrence.

Until it's addressed, improve ventilation in the room by opening windows when outdoor humidity is lower (typically early morning or evening) and consider using a dehumidifier. Do not attempt to clean extensive growth yourself with bleach, as improper scrubbing can aerosolize a high number of spores and worsen the problem. The goal is to identify the moisture source, eliminate the growth, and repair the AC system to prevent it from happening again.
