Mold in my AC closet: DIY or call a professional?« Back to Previous Page

Based on the symptoms you've described – persistent AC leakage, spreading black spots on porous surfaces like drywall and textiles, and a persistent musty odor – this is a clear case of active mold growth that requires professional intervention. The UAE's high humidity, especially during summer months, creates an ideal environment for mold, and a leaking AC unit is a constant source of moisture.

While vinegar can kill some surface mold, it is ineffective against the hyphae (root structures) penetrating porous materials like wall plaster and clothing. Stronger, off-the-shelf biocides are not recommended; they can be hazardous to handle, may not be approved for use in the UAE, and often only bleach the visible growth without addressing the root cause or the mycotoxins. Furthermore, improper cleaning can aerosolize spores, spreading the contamination to other areas of your home.

In Dubai, professional remediation is strongly advised. Our process involves a certified inspection to identify the species and extent of contamination, followed by source correction (fixing the AC leak). Remediation includes containment of the area with negative air pressure to prevent cross-contamination, HEPA vacuuming, and the application of specialized, approved antimicrobial agents to eliminate the colony at its source. The affected drywall and unsalvageable textiles often need to be safely removed and disposed of.

Given the health risks and potential for structural damage, I recommend you cease DIY efforts and contact a certified professional.
