AC leak causing mold in bedroom: clean or call professional« Back to Previous Page

Stop the AC unit immediately to prevent further water damage. The black spots indicate active mold growth, which is common in Dubai's humid climate when condensation or leaks occur.

For small areas (under 1 square meter), you can clean it yourself. Wear an N95 mask and gloves. Scrub the affected wall and baseboard with a mixture of detergent and water, then wipe with a diluted bleach solution (1 part bleach to 10 parts water). Dry the area completely with a fan. However, this only addresses surface mold. The damp carpet pad underneath is likely a larger, hidden reservoir that requires professional extraction and drying to prevent regrowth.

The AC leak must be fixed permanently by a certified HVAC technician. Common causes in UAE units include a clogged condensate drain line, which is frequent due to dust, or a misaligned drain pan. Simply cleaning the visible mold without repairing the leak will result in it returning quickly.

For a situation involving wet carpet and wall penetration, a professional inspection is recommended. They can use moisture meters to assess the full extent of the damage behind the wall and under the carpet, which is often worse than it appears. Reputable providers should be able to show certification, such as from the Dubai Municipality, and provide a clear scope of work for both the water damage restoration and mold remediation. Fix the AC first, then address the moisture damage thoroughly.
