How to treat mold from AC leak and fix it?« Back to Previous Page

First, stop the moisture source. Turn off the AC unit to prevent further leakage. The black spots are likely Cladosporium or Aspergillus, two common types in Dubai's humid climate that thrive on condensation from AC leaks.

For a small area, wear an N95 mask and gloves. Wipe the visible mold on hard surfaces with a microfiber cloth and a solution of detergent and warm water. Do not use bleach, as it doesn't prevent regrowth and can damage porous materials. For the damp carpet, thorough drying is critical; use wet vacuums and fans, but be aware that mold roots can penetrate deep into carpet fibers, making complete DIY removal difficult.

The underlying cause is the AC leak, which must be professionally repaired. A certified HVAC technician should be called to fix the drain line clog, condensate pump failure, or improper installation that is causing the water leakage. This is a permanent fix to prevent recurrence.

Given the leak has been ongoing for weeks, moisture has likely spread behind the wall. Surface cleaning addresses only what you see. For a proper assessment of hidden mold and to verify successful remediation, a professional inspection with moisture meters and, if necessary, lab testing of samples is recommended. This is the only way to confirm the environment is dry and the mold has been adequately addressed.
