How to fix AC leak and remove black mold permanently?« Back to Previous Page

The black spots you've described are almost certainly Cladosporium or Stachybotrys (toxic black mold), a direct consequence of the AC condensate leak. In Dubai's high-humidity climate, this creates a perfect breeding ground. Your husband's respiratory symptoms (stuffy nose, cough) are classic indicators of mold exposure, which can escalate to more severe allergic reactions or asthma.

Addressing this requires a two-phase professional approach, as per UAE's strict environmental health and safety guidelines. First, the moisture source must be eliminated. A certified HVAC technician should inspect the unit, likely clearing a blocked condensate drain line or repairing a faulty drain pan—common issues here due to dust and year-round AC operation. Simply cleaning the mold is insufficient and hazardous, as improper disturbance releases mycotoxins into the air.

For permanent remediation, the affected wardrobe and potentially the wall cavity behind it require expert intervention. Our certified mold remediation team at Saniservice follows a strict protocol: we first isolate the area with negative air pressure to prevent cross-contamination, then safely remove and dispose of the infested materials. The area is then treated with EPA-approved, non-toxic antimicrobial agents and sealed. Finally, we use air scrubbers with HEPA filtration to purify the air of all particulate matter.

To prevent recurrence, ensure your AC unit receives bi-annual professional servicing, including coil cleaning and drain line flushing. Maintaining indoor relative humidity below 60% is critical; using a dehumidifier in conjunction with your AC can help achieve this.

Given the visible growth and accompanying health symptoms, a professional inspection is strongly advised to determine the full extent of the contamination.
