Is our AC mold making us sick and how to fix?« Back to Previous Page

The black spots and your symptoms are a strong indication of a mold issue, likely caused by the AC condensate leak. The persistent dampness from the leak, combined with Dubai's high humidity, creates the perfect environment for mold to grow. The spores can then be circulated by the AC, leading to the respiratory irritation you're both experiencing.

For a situation like this behind a fixed wardrobe, professional remediation is the safest and most effective route. The process should start with a proper inspection, often using a borescope to see behind walls without demolition, to assess the full extent. Reputable companies will then contain the area to prevent spores from spreading to other parts of your apartment during the work.

The remediation itself involves removing the contaminated materials (like affected drywall or insulation), HEPA vacuuming all surfaces, and using professional-grade antimicrobial solutions to treat the area. Crucially, the root cause—the AC leak—must be repaired by an HVAC technician to prevent immediate recurrence.

To be sure it's completely resolved, the standard is post-remediation verification (PRV). This is a separate inspection, often involving air and surface sampling sent to an independent microbiology lab, to confirm spore counts are back to normal indoor levels. You should receive a detailed report with these lab results as your proof that the issue has been successfully addressed.
