How to clean mold from AC leak and fix permanently?« Back to Previous Page

For a small patch from an AC leak, the best DIY approach is to wear an N95 mask and gloves. Mix one part unscented household bleach with four parts water. Scrub the affected wall base with a stiff brush, then wipe clean with a damp cloth. Dry the area completely with a fan; in Dubai's humidity, a dehumidifier is essential to prevent immediate regrowth. The carpet pad underneath is likely compromised and may need cutting out and replacement to fully address the hidden moisture source.

To fix the AC leak permanently, you must contact a licensed HVAC technician. The leak is likely due to a clogged condensate drain line, a common issue here from dust and biofilm buildup. A proper fix involves rodding or pressure-jetting the drain line and possibly installing a float switch to prevent future overflows. For the mold, if the affected area is larger than one square meter, or if you notice a persistent musty smell after cleaning, a professional indoor health inspection with air and surface sampling is recommended to confirm the mold has been adequately removed and spore levels are safe.
