AC leak caused black mold and sinus issues in Dubai?« Back to Previous Page

You're describing classic symptoms of mold exposure from an AC leak. In Dubai's humid climate, even small leaks create ideal conditions for mold growth behind walls and in ceiling cavities.

The black fuzzy patches are likely Cladosporium or Stachybotrys (black mold), both common in water-damaged UAE buildings. Your persistent sinus congestion and cough are strong indicators the mold is affecting your indoor air quality. This requires professional assessment, not just a surface clean.

You need a certified mold inspector, not a general handyman. Look for a company that conducts a full assessment including moisture mapping with thermal cameras and air quality testing. They should take samples for a microbiology lab to identify the exact species and spore count – this is crucial for understanding health risks and planning proper remediation.

The remediation process itself involves isolating the area, removing contaminated materials like drywall or insulation, HEPA vacuuming, and antimicrobial treatment. Simply wiping the visible mold won't address the root problem or the spores in the air.

After remediation, request a clearance test to verify spore counts have returned to safe levels. Finally, have an HVAC technician fix the AC leak permanently to prevent recurrence. Addressing the source of moisture is the most critical step.
