The Dubai climate is a significant contributing factor. The extreme humidity, combined with year-round air conditioning, creates massive condensation issues. If the AC unit is not properly maintained or if there is a leak in the condensate drain line, it creates a constant source of moisture—the primary requirement for mold growth. The patch you found under the carpet near the vent is a clear sign of this moisture intrusion.

Your family’s symptoms—persistent cough in a child, morning headaches, and general malaise—are common health effects of prolonged mold exposure, particularly in individuals with respiratory sensitivities or compromised immune systems.

Given the severity of these symptoms and the confirmed visual growth, I strongly recommend you cease using that AC unit immediately and seek a professional indoor environmental inspection. DIY testing is not advisable, as improper handling can exacerbate spore dispersal. In the UAE, remediation must comply with strict guidelines to ensure complete removal and prevent recurrence.

Our certified team at Saniservice uses advanced techniques like thermal imaging to locate moisture sources and air sampling to identify spore types and concentration levels. We provide a comprehensive report and a remediation plan that meets all local regulatory standards. For immediate assistance, please call us at 800-MOLDS (800-66537) or email hello@saniservice.com to schedule an inspection. Your family’s health is paramount.
