AC leak causing black mold and cough: professional cleanup needed?« Back to Previous Page

Based on your description, you are almost certainly dealing with a significant mold infestation, specifically Stachybotrys chartarum (black mold) or Aspergillus niger, which are common in Dubai due to the constant AC use and high humidity. The persistent cough and nasal congestion are classic symptoms of mold exposure.

The AC leak has created a persistent moisture source behind the wardrobe, a perfect environment for mold to thrive unseen. This is not a surface issue you can clean yourself. Disturbing it without proper containment will aerosolize the spores, drastically increasing your exposure and contaminating other areas of your apartment.

For a professional and compliant remediation in the UAE, the process must be thorough:

1. Inspection & Testing: A certified inspector will conduct a visual assessment and take air and surface samples to identify the mold species and spore concentration levels, both inside the affected wall cavity and in your bedroom air. This report is crucial for guiding the remediation and for post-clearance testing.
2. Containment: The area must be sealed with plastic sheeting and put under negative air pressure using HEPA-filtered air scrubbers. This is critical to prevent cross-contamination to other parts of your home during the work.
3. Removal & Remediation: The affected section of drywall and insulation behind the wardrobe will need to be safely removed and disposed of. All remaining structures will be HEPA-vacuumed and treated with EPA-approved antimicrobial solutions.
4. AC Unit Servicing: The root cause—the leaking AC unit—must be repaired by a certified HVAC technician to prevent immediate recurrence.
5. Post-Remediation Verification: After cleanup, a final air quality test is essential to confirm the spore count has returned to safe levels before the containment is removed.

Should you relocate? Yes, absolutely. For the health of your family and to allow the technicians to set up proper containment, you should arrange to stay elsewhere until the post-remediation clearance test confirms the environment is safe.
