Bleach spray for AC mold or call a professional?« Back to Previous Page

That black speckling is almost certainly active mold growth, and your scratchy throat is a common symptom of exposure. In Dubai's high humidity, a small AC leak creates the perfect breeding ground for mold, which can spread through spores in just days.

Bleach is not recommended. It's mostly water, which can feed the mold's roots inside your wall. The chlorine evaporates quickly, only bleaching the visible surface while leaving the main colony intact to regrow. It also releases harsh fumes into your bedroom air.

This situation requires a professional assessment. The leak must be fixed first—no cleaning will be effective if the moisture source remains. The mold on your wall and curtains is just the visible part; the internal AC unit and the wall cavity behind it are likely colonized. A proper remediation involves containing the area, removing contaminated porous materials like drywall and fabric, and using specialized antimicrobials on the AC system itself.

For a confirmed issue of this scale, especially with health symptoms, a certified mold inspector can identify the species and the full extent of the problem. In many cases, a professional remediation company is necessary to ensure it is removed safely and doesn't return with the next humidity spike.
