AC mold causing my husband's cough and stuffy nose?« Back to Previous Page

The persistent cough and congestion are very likely connected to the mold growth from the AC leak. In Dubai's climate, constant AC use creates condensation, and any leak provides the perfect damp environment for mold to thrive, often within weeks. The black patches you see are just the visible part; the root issue is likely inside the AC unit or the wall cavity.

For his health, a doctor's visit is advisable to address the symptoms and confirm if they are allergy or irritation-based. Explain the mold exposure to them. For the mold, this requires a professional approach. Wiping the wall is a temporary fix. The AC unit must be inspected, cleaned, and the leak repaired to stop the moisture source. The wall may need specialized drying and treatment to prevent spores from spreading.

The fastest, most effective method is a combined inspection and remediation process. Look for a provider that uses moisture meters and borescopes to assess the wall cavity and AC drip pan, followed by containment procedures during cleaning to avoid cross-contamination. Post-remediation verification, ideally with air or surface sampling, confirms the environment has been returned to a healthy state. This comprehensive approach is the standard for resolving such issues permanently.
