AC Leak Causing Mold in Bedroom: How to Fix?« Back to Previous Page

Based on your description, this is a classic case of condensation-induced mold growth, a very common issue in Dubai's climate due to high humidity and year-round AC operation. The black spots are likely Cladosporium or Stachybotrys, which thrive in damp, cellulose-rich materials like carpet backing and drywall.

The priority is not just cleaning the visible mold but addressing the source. The continuous AC leak is providing the moisture necessary for mold to recur. The unit likely has a blocked condensate drain line or a malfunctioning drain pan, which must be rectified by a certified HVAC technician. I strongly advise against attempting to fix the AC unit yourself, as improper handling can exacerbate the problem.

For the mold, wiping visible growth is a temporary measure. The moisture has likely penetrated the carpet underlay and the skirting board, creating a hidden reservoir. In the UAE, mold remediation is governed by strict hygiene and public health regulations (UAE.S 5019:2015) to ensure it is handled safely and effectively. Disturbing it improperly can aerosolize spores, leading to wider contamination and potential health issues.

Given the persistent leak and visible growth, a professional inspection is crucial. A certified mold inspector will use moisture meters and thermal imaging to assess the full extent of the water damage and hidden mold, then provide a protocol for remediation.

For a permanent solution, you need a two-pronged approach: First, a licensed HVAC company to repair the AC leak at its source. Second, a specialized remediation company like Saniservice to properly contain the area, remove the affected materials (carpet, underlay, potentially a section of drywall), and perform antimicrobial treatment to ensure the mold is eradicated. For immediate advice and inspection, I recommend calling Saniservice at 800-MOLDS (800-66537) or emailing hello@saniservice.com. They can coordinate both the inspection and the necessary repairs to resolve this permanently.
