Black mold in AC unit: professional removal or DIY with bleach?« Back to Previous Page

Based on your description of a leaking AC unit in Jumeirah and the subsequent black, fuzzy growth, I strongly advise against a DIY bleach treatment. The UAE's high humidity, especially during summer, creates a perfect environment for mold, and what you're describing is a classic case of condensation-related growth, often from a clogged AC drain line or faulty insulation.

While it may appear superficial, the fuzzy texture suggests active growth that has likely penetrated the porous drywall. Bleach is ineffective on porous surfaces; it only bleaches the surface color and does not kill the roots (hyphae). More critically, improper disturbance can aerosolize highly concentrated spores, significantly worsening your children's allergy symptoms and posing respiratory risks.

Professionally, this requires a multi-step process: first, identifying and repairing the moisture source (the AC leak), then containing the area to prevent cross-contamination, followed by the safe removal of affected materials, HEPA vacuuming, and antimicrobial application. The cost for a localized remediation like this in a Dubai apartment typically ranges from AED 1,500 to AED 4,000, depending on the extent of wall damage behind the curtain.

Given the health concerns for your family, a professional inspection is not just recommended, it is necessary.
