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

The black patches are likely mold growth, a common result of AC condensation leaks in Dubai's humid climate. The damp smell confirms active microbial growth.

For small patches (under 1 sq. ft.), you can clean it yourself with a solution of white vinegar and water. Scrub the area, let it sit for an hour, then dry it thoroughly. Do not use bleach, as it doesn't kill the roots and can worsen indoor air quality. However, since the mold is on porous carpet and the leak is from the AC, this is likely a temporary fix. The moisture has probably seeped into the underpad and possibly the subfloor.

The priority is stopping the source. You must call a certified HVAC technician to repair the AC drain line or condensate pump. Simply wiping the water is not a solution; the system needs a professional fix to prevent recurrence.

Given the persistent leak over an unknown period, a professional inspection is strongly recommended. Mold spores from the carpet can become airborne and circulate through your AC to other rooms. A proper assessment involves moisture meters to check the walls and subfloor for hidden dampness that you cannot see. In many cases, the carpet and underlay must be removed to properly dry and treat the area. For verification, a lab test can identify the mold type, which is particularly advised if household members have allergies or respiratory sensitivities.
