AC leak causing black spots and sickness: urgent?« Back to Previous Page

Yes, this requires professional assessment within days, not weeks. The combination of visible black spots and recurring morning symptoms strongly suggests active mold growth, which is common in Dubai's climate where AC condensation and high humidity create ideal conditions.

The black spots are likely Cladosporium or Aspergillus, molds frequently identified in water-damaged UAE homes. Their spores become airborne, leading to the nasal congestion and headaches your wife is experiencing. Continuing to sleep in that room will likely worsen symptoms.

For a leak of this duration, surface cleaning is insufficient. The carpet pad and possibly subflooring underneath are almost certainly saturated and contaminated. Professional remediation involves removing the affected carpet section, treating the concrete beneath with antimicrobial agents, and using industrial air scrubbers to capture spores during the process.

Do not attempt to clean it yourself with bleach, as this can agitate the spores without addressing the root moisture problem, potentially making the air quality worse. Keep the bedroom door closed and the AC off in that room to prevent spore circulation until it's assessed.

Schedule an inspection with a provider that uses moisture meters and thermal cameras to find all hidden dampness. They should also be able to provide post-remediation verification, such as air testing, to confirm the space is safe. In Dubai, this level of documented clearance is a best practice for health-sensitive areas like bedrooms.
