Is AC mold causing my child's cough in Dubai?« Back to Previous Page

The AC in our Jumeirah villa has been leaking a bit for a couple of months, and now we’ve found a patch of black mold in the closet on the adjacent wall. My youngest has had a runny nose and a nagging cough for weeks that just won’t go away. Is this likely from the mold, and what’s the fastest way to deal with it properly here in Dubai?

Based on the symptoms and situation you've described, it is highly probable that the mold growth from the AC leak is contributing to your child's persistent respiratory issues. The black patch in the closet is a visible indicator of a moisture problem, and it is very likely that a significant colony is also present within the AC unit and its ductwork, which is then being aerosolized and circulated throughout your villa's air.

In Dubai's climate, where high external humidity forces us to rely on year-round air conditioning, these systems are a primary vector for mold proliferation. Condensation from minor leaks creates the perfect damp, dark environment for spores to thrive. The constant recirculation of contaminated air can lead to precisely the symptoms you describe: chronic runny nose, coughing, and other allergic reactions, particularly in children who are more susceptible.

The fastest and most proper way to deal with this is a two-step professional process. First, a certified mold inspection, including air and surface sampling, is crucial to identify the full extent of the contamination, both visible and hidden. DIY cleaning is not recommended as it often disturbs spores without eliminating the source, worsening airborne concentrations. Second, remediation must address the root cause: the AC leak must be repaired by a certified HVAC technician. Following this, the mold itself must be professionally remediated. This involves containment of the affected area, HEPA filtration to capture airborne spores, and the proper use of antimicrobial agents to eliminate the growth.
