AC mold inside wall: DIY clean or call professional?« Back to Previous Page

That black and green mold from a leaking AC is a serious concern, and wiping it with bleach only addresses the surface. The persistent smell confirms the issue is likely inside the wall cavity, where mold feeds on the damp drywall and insulation. In Dubai's high humidity, this hidden growth can spread rapidly.

You absolutely need a professional assessment. DIY cleaning products cannot reach the contamination inside the wall, and improper handling can aerosolize spores, spreading them to other rooms. The wall itself may need to be opened, the affected materials safely removed, and the area properly dried before the leak is even fixed.

The core issue is the AC leak, which must be repaired by an HVAC technician to prevent immediate recurrence. Any remediation company you call should first identify the moisture source. For a situation involving structural elements like drywall, a professional inspection with tools like moisture meters is critical to determine the full extent. A company with its own microbiology lab can also provide air and surface testing to verify the space is safe after remediation, which is the only way to be certain the problem is resolved.
