Is AC mold causing my husband's illness?« Back to Previous Page

Yes, the AC mold is very likely causing your husband's symptoms. The black spots indicate active growth, and his morning congestion and headaches that resolve away from the bedroom are classic signs of mold exposure. The persistent moisture from the leak creates an ideal environment for mold, especially in Dubai's humidity.

You should treat this as urgent. The continuous leak means the problem is not just on the wall surface but likely inside the AC unit and possibly the wall cavity itself. For your health, sleeping in another room is strongly recommended until the issue is resolved. This will immediately reduce his exposure and should alleviate the morning symptoms.

In Dubai, this requires a two-part professional approach. First, an HVAC technician must fix the condensate drain line leak to stop the moisture source. Second, a mold assessment is critical to determine the extent of the growth. Surface cleaning alone is insufficient if the mold has penetrated porous materials like drywall, which often requires removal and replacement. Look for a provider that uses lab analysis to identify the mold type, as this dictates the correct remediation protocol. Proper remediation should include containment of the area to prevent spores from spreading to other parts of your home during the work.
