How to treat AC mold and fix leak in Dubai?« Back to Previous Page

The constant AC leakage you describe in your Jumeirah Village Circle apartment is a classic and serious issue in Dubai's high-humidity climate. The condensation from your AC unit creates a perpetually damp environment, which is the primary condition for rapid mold proliferation. The black substance you see is almost certainly mold growth.

For immediate, superficial treatment, you can carefully clean the visible area with a solution of distilled white vinegar or a proprietary mold-cleaning agent. However, this is only a temporary cosmetic fix. The mold's root system (hyphae) will remain embedded within the wall's porous surface, and the growth will return as long as the moisture problem persists. Attempting to treat it yourself also risks disturbing the colony and releasing a high concentration of spores into your indoor air, which can cause significant health issues.

The root cause is a malfunction in your AC's condensation removal system. This could be a blocked condensate drain line, a damaged drain pan, incorrect unit levelling, or a refrigerant leak causing excessive ice formation and subsequent melting. This is a job for a certified HVAC technician, not a general handyman. They must be called to perform a full diagnostic, clear the drain line with a vacuum or pressure jet, and repair any faulty components to stop the leak permanently.

Given the visible growth, a professional mold inspection is strongly advised. We use thermal imaging and moisture meters to map the full extent of the moisture penetration and spore spread, which is often far greater than what is visible. Our hygienists then perform a controlled remediation, including HEPA vacuuming, antimicrobial application, and if necessary, drywall replacement to ensure the colony is completely eradicated.
