AC leak causing black mold: DIY or call a pro?« Back to Previous Page

Based on your description, this is a classic case of AC-induced mold growth, extremely common in Dubai due to our high humidity and year-round reliance on air conditioning. The black spots near the vent are a significant indicator, and the fact that they returned after a bleach wipe is a major red flag.

Bleach is a surface-level treatment and is ineffective on porous materials like drywall and insulation. The persistent smell confirms the mold colony is active and likely proliferating inside the wall cavity, fed by the ongoing moisture from the AC leak. This hidden growth is what continues to release mycotoxins and volatile organic compounds (VOCs), causing the odor and potential health risks.

A DIY approach with a cleaner from ACE is not recommended. It addresses only the cosmetic surface issue, not the root cause. Disturbing the mold improperly can aerosolize spores, spreading the contamination throughout your bedroom and HVAC system.

A professional inspection is absolutely necessary. Our certified inspectors use tools like borescopes to visually assess contamination inside walls and air quality tests to identify spore types and concentration levels, which is critical for determining the correct remediation protocol as per UAE standards.

The remediation process must first stop the water intrusion by having an AC technician repair the leak. Then, our team would perform contained removal of affected materials, HEPA vacuuming, and application of EPA-approved antimicrobials. Finally, we would use industrial dehumidifiers to ensure the cavity is bone-dry to prevent recurrence.

For a thorough assessment and a permanent solution, I strongly advise you to call our specialists at Saniservice. You can reach us at 800-MOLDS (800-66537) or email hello@saniservice.com to schedule an inspection.
