How to dry AC leak and prevent mold in wall?« Back to Previous Page

A small AC leak in a Dubai apartment can quickly lead to a mold issue due to our high humidity. Your immediate priority is to stop the moisture source and dry the area completely.

First, turn off the AC unit at the circuit breaker to prevent electrical issues and further water leakage. Soak up all standing water with towels. For the damp carpet, lift it if possible and use a wet-dry vacuum to extract as much moisture as you can. Place a dehumidifier and fans directly at the site; in our climate, this accelerated drying may take 24-48 hours. For the wall, wipe the visible speckles with a solution of diluted detergent, but avoid oversaturating it. Do not use bleach, as it doesn’t prevent regrowth and can damage surfaces.

The real concern is hidden mold inside the wall cavity and AC unit, which you cannot effectively treat yourself. The damp smell indicates microbial growth is already present. A professional inspection with a borescope can assess the wall interior, and an AC technician can diagnose the leak's cause—often a clogged drain line or faulty condensate pump, which are common issues with continuous use here.

For verification, surface sampling can identify the mold type. In many cases, localized wall cavities require controlled removal and application of antimicrobial coatings to prevent recurrence, a job for remediation specialists to ensure it's contained. Simply drying the surface is not a permanent solution when the wall’s interior has been wet.
