Should I remove mold from AC leak myself or call professional?« Back to Previous Page

Based on your description, you should call a professional for an assessment. The combination of an AC leak, a hidden area behind furniture, and a persistent musty smell after cleaning indicates a problem that likely extends beyond the visible surface.

In Dubai's climate, AC condensation leaks are a primary cause of indoor mold. The high humidity provides a constant moisture source, allowing mold to penetrate porous materials like drywall and concrete block. Vinegar or bleach only address surface discoloration; they cannot remove the root structure (hyphae) growing deep within the wall. The lingering smell confirms the colony is still active.

For a situation involving a recurring leak and structural materials, a professional inspection is the safest approach. They use moisture meters and borescopes to assess the damage within the wall cavity, which is critical for proper remediation. DIY attempts can inadvertently release a large number of spores by disturbing the colony without proper containment.

The process involves identifying and repairing the AC leak first, isolating the affected area, safely removing contaminated porous materials, and using HEPA filtration to clean the air. Surface disinfectants are only applied at the final stage. For verifiable results, the company should provide before-and-after documentation, such as lab analysis, to confirm the spore count has returned to acceptable levels.
