Could AC mold be causing our family's persistent cough?« Back to Previous Page

Based on the symptoms and scenario you've described, it is highly probable that microbial growth (mold) from the AC leak is the source of your family's persistent respiratory issues. The combination of water intrusion from a leaking AC unit and the high humidity inherent to Dubai's climate creates an ideal breeding ground for mold, particularly behind furniture like wardrobes where air circulation is poor. The black spots and strong musty odor are classic indicators of a significant colonization.

The persistent cough and stuffy nose are common allergic reactions to inhaled mold spores and microbial volatile organic compounds (mVOCs). In enclosed spaces like a bedroom, especially with continuous AC recirculation, spore concentration can become high enough to cause these symptoms in otherwise healthy individuals. Children can be particularly susceptible.

The first and most critical step is to immediately address the moisture source. You must have the AC unit inspected and repaired by a qualified HVAC technician to stop the leak. Do not attempt to clean the visible growth yourself, as improper disturbance will aerosolize a high concentration of spores throughout the room, potentially worsening your symptoms and contaminating other areas.

For a situation of this nature, with confirmed water damage, visible growth, and health symptoms, a professional indoor environmental inspection is strongly recommended. Our certified inspectors at Saniservice conduct a comprehensive assessment that includes moisture mapping, thermal imaging to identify hidden dampness, and air/surface sampling to identify the specific genus of mold present. This data is crucial for developing an effective remediation protocol that complies with Dubai Municipality's strict health and safety standards for indoor air quality.

I advise you to cease use of the affected AC unit, increase ventilation in the room, and contact a professional for assessment. For immediate assistance, you can call our experts at 800-MOLDS (800-66537) or email hello@saniservice.com to schedule an inspection.
