Could AC mold cause my husband's persistent cough?« Back to Previous Page

Yes, it is very possible. The black spots are likely mold growth caused by the continuous moisture from your AC leak. In Dubai's climate, where high humidity and constant AC use create ideal conditions for mold, this is a common issue. The persistent dry cough is a classic symptom of mold exposure, as airborne spores irritate the respiratory tract.

The leak itself provides the moisture mold needs to thrive on dust and organic material in your wardrobe and the AC unit. When the system operates, it can then blow these spores directly into your bedroom's air. For individuals with sensitivities or underlying respiratory conditions, this can lead to ongoing irritation and a cough that doesn't resolve.

You should address this promptly. First, stop the source of moisture by having a certified HVAC technician repair the AC leak. For the existing growth, a professional inspection is strongly recommended to assess the extent. Surface cleaning on the wardrobe may not be sufficient if mold has penetrated the material or is growing within the AC unit itself.

A proper assessment involves more than a visual check; it includes moisture mapping and often air or surface sampling to identify the mold species and concentration. This is crucial for determining the correct remediation strategy and for your peace of mind, as it confirms whether the indoor environment is the likely cause of the health symptoms. In many cases, a thorough professional remediation can significantly improve the air quality and alleviate such symptoms.
