Is our AC's black mold causing our cough?« Back to Previous Page

Black mold growth from AC leaks is a common cause of the symptoms you describe, especially in Dubai's climate where high humidity and condensation create ideal conditions for it. The persistent dry cough and headaches are typical reactions to prolonged exposure to mold spores circulating in your indoor air.

The safest approach is to first identify the source. The fuzzy patch on the wall is a visible sign, but the leak inside the AC unit likely harbors the primary colony. Do not attempt to clean it with bleach or DIY sprays, as this can aerosolize a high concentration of spores and exacerbate your symptoms. Disturbing it without proper containment can spread the problem throughout the apartment.

For a situation involving health symptoms and a recurring leak, a professional inspection is strongly advised. In the UAE, reputable remediation companies follow standards from bodies like the Indoor Environmental Health Association. They will conduct a thorough assessment to map the moisture source and extent of growth, often using moisture meters and borescopes to inspect inside the AC unit and walls. The actual remediation involves isolating the area, using HEPA filtration to capture spores, and safely removing contaminated materials.

After remediation, the AC leak must be permanently repaired by a qualified HVAC technician to prevent immediate recurrence. For your health, improving ventilation by opening windows when outdoor humidity is lower (typically early morning or evening) can help reduce spore concentration while you arrange for an assessment.
