AC leak causing mold and health symptoms?« Back to Previous Page

Our AC unit in the bedroom has been leaking a bit for the last month and now I've found black spots spreading on the wall behind the wardrobe. My husband and I have both been waking up with sore throats and stuffy noses that clear up once we leave for work. Is this likely mold-related and could it be causing these symptoms, or is it just a coincidence?

Based on your description, this is a classic and serious case of mold growth directly resulting from the AC condensate leak. The black spots are almost certainly mold, and the health symptoms you and your husband are experiencing are strongly indicative of mold exposure.

In Dubai's high-humidity climate, air conditioning units are a primary source of moisture intrusion when they malfunction. A continuous leak provides the perfect environment for mold colonies, particularly Stachybotrys chartarum (black mold) and Aspergillus, to proliferate inside your wall cavity. The fact that your symptoms (sore throats, nasal congestion) resolve when you leave the bedroom environment is a key diagnostic indicator that the mold spores in that room are the likely irritants, affecting your respiratory systems.

This is not a coincidence. Prolonged exposure can exacerbate these symptoms and lead to more severe health issues. Do not attempt to clean this yourself. Disturbing the mold without proper containment will aerosolize the spores, spreading the contamination throughout your bedroom and HVAC system.

This situation requires immediate professional assessment. Regulations in the UAE, particularly from Dubai Municipality, emphasize the importance of professional remediation to ensure the health and safety of occupants and the correct disposal of contaminated materials. Our certified inspectors at Saniservice use thermal imaging cameras to pinpoint the exact extent of the moisture damage and take air and surface samples to identify the specific mold species, which guides the remediation protocol.
