AC mold spreading in Mirdif villa: DIY or call professional?« Back to Previous Page

The recurring musty smell indicates active mold growth inside the AC unit or ductwork, which vinegar cannot address. In Dubai's high humidity, AC condensation creates a constant moisture source, allowing mold to regrow quickly after surface cleaning.

For a leak that has persisted for months and spread behind a wall, this is beyond a DIY fix. The mold colony is likely extensive and embedded within the wall cavity, requiring controlled removal to prevent spore dispersal. Professional remediation is necessary to properly contain the area, remove contaminated materials like drywall or insulation, and treat the AC system internally to stop the contamination source.

In the UAE, reputable companies follow specific protocols for containment and removal to prevent cross-contamination. They should also provide a post-remediation verification test from an independent lab to confirm the spore count has returned to normal indoor levels. This is the only way to ensure the musty odor and health risks are fully resolved. Start by having a certified mold inspector assess the full extent of the damage behind the wall and inside the AC unit.
