How to remove mold from AC and prevent recurrence?« Back to Previous Page

The damp, earthy smell and black spots indicate active mould growth, a common issue in sealed Dubai villas where high humidity meets cold AC surfaces. For proper removal, the entire AC system—evaporator coils, drip pan, and ducting—must be professionally cleaned with EPA-registered antimicrobial solutions, not just the visible vent. In many cases, the internal insulation is contaminated and requires replacement.

To prevent recurrence, address the humidity source. After professional remediation, maintain indoor humidity below 60%, ideally 45-55%. A dedicated dehumidifier, sized for your bedroom, is essential. Ensure your AC unit is correctly sized and set to a temperature that minimizes excessive condensation; running it slightly warmer but more consistently can help. Keep bathroom vents operational and avoid drying clothes indoors. For a lasting solution, a professional assessment can identify specific ventilation upgrades or system flaws unique to your villa's construction.
