Can I clean AC mold or need a professional?« Back to Previous Page

A leak from your AC unit, combined with Dubai's high humidity, has created the perfect environment for mold growth. The black spots spreading on the wall indicate the moisture has penetrated the building material itself, which is a serious concern.

For a small, surface-level patch on a non-porous tile, a diluted bleach solution might temporarily remove the visible stain. However, on porous surfaces like drywall or plaster, bleach often fails to kill the roots and can even add moisture, worsening the problem over time. Given that the mold is behind a wardrobe and stemming from an AC leak, the infestation is likely more extensive than what is visible.

This situation warrants a professional assessment. The leak must be repaired first to stop the moisture source. A proper remediation process involves containing the area to prevent spores from spreading, removing contaminated porous materials like affected drywall, and using specialized antimicrobials on the structure. In the UAE, reputable companies follow standards like the IICRC S520 for mold remediation.

Attempting a DIY clean on a persistent leak-related issue risks inadequate removal and allows hidden mold to continue affecting your indoor air quality, which can exacerbate allergies and respiratory issues. Given the climate, a professional can also identify if your AC unit itself is contaminated and requires internal cleaning.
