AC mold from leak: DIY bleach clean or call professional?« Back to Previous Page

The black mold from your AC leak is a common issue in Dubai's humid climate, where condensation provides constant moisture. A small, surface-level patch you can fully access might be handled with a bleach solution (1 part bleach to 10 parts water), but this only removes surface discoloration and won't kill the roots or address the hidden moisture source.

For your situation, a professional inspection is strongly recommended. The mold is on porous materials (drywall, jackets) and stems from an active leak, meaning the problem is likely more extensive inside the wall or AC unit itself. DIY cleaning often spreads spores and misses the root cause, leading to rapid regrowth.

In Dubai, reputable remediators don't just clean; they use moisture meters to find the leak's origin, HEPA vacuums to contain spores, and antimicrobial treatments. They can also advise on preventing recurrence, which is critical with our year-round AC use. For verifiable results, choose a provider that documents the process with before-and-after imagery and, if needed, can provide a clearance test from an independent lab to confirm the space is safe.
