Is AC mold causing my wife's persistent cough?« Back to Previous Page

The black spots and persistent cough are likely connected. AC mold can cause respiratory irritation, and in Dubai's humid climate, a leaking unit creates the perfect environment for it to grow. While not all black mold is the toxic Stachybotrys variety, any mold can trigger coughing, congestion, and worsen allergies, especially in individuals with sensitivities.

You should address this promptly. For a leak that has lasted weeks and visible growth, a DIY approach is not recommended. Cleaning the visible spots with bleach only addresses the surface and misses spores within the AC unit and wall cavity, allowing the problem to return quickly. The leak itself must be repaired to prevent recurrence.

In Dubai, the continuous AC operation creates significant condensation, and unresolved leaks lead to persistent dampness. A professional inspection is advised to identify the mold species via lab testing and assess the full extent of the moisture damage, which often extends behind walls. They can then execute a proper remediation protocol that includes containing the area to prevent spore spread, safely removing contaminated materials, and using industrial-grade equipment to dry the structure completely. The primary step is fixing the AC leak; no cleaning will be effective without eliminating the source of moisture.
