Is our mold causing headaches and stuffy noses?« Back to Previous Page

Black mould growth from AC leaks is a common cause of the symptoms you describe. The constant stuffy nose and headaches are a classic reaction to mould spores and microbial volatile organic compounds (mVOCs) released into the air, especially in a sealed bedroom environment. Dubai's high humidity and year-round AC use create ideal conditions for this issue.

Your first step is to stop the moisture source. Have a certified HVAC technician repair the AC leak immediately; this is non-negotiable. For the visible growth, avoid disturbing it yourself, as this can aerosolize spores. Do not attempt to clean it with bleach, as it only bleaches the colour and does not kill the root structure.

Given the symptoms and the extent of spread behind furniture, a professional inspection is strongly advised. In Dubai, look for a provider that conducts a thorough assessment, including moisture mapping and, if necessary, air or tape-lift sampling to be analysed at a microbiology lab. This identifies the species and concentration, which is crucial for determining the appropriate remediation protocol. The process should be fully documented for your landlord, as they are typically responsible for resolving such issues under tenancy laws. Proper remediation involves containment, HEPA-filtered air scrubbing, and the removal of contaminated porous materials like damaged drywall.
