Could black mold cause our cough and headaches?« Back to Previous Page

Yes, the black mould from your AC leak could very likely be the cause of your persistent dry cough and headaches. These are two of the most common symptoms of mould exposure, which occurs when you inhale the microscopic spores and microbial volatile organic compounds (mVOCs) it releases into the air. The continuous operation of your AC in Dubai's climate circulates these particles throughout the room, creating a sustained exposure.

Given that the leak has persisted for months, the visible patch is likely just a fraction of the growth; mould thrives in damp, dark cavities and can spread extensively within wall interiors and the AC unit itself behind the scenes. This isn't something a simple wipe-down can fix, as the root moisture problem and hidden colonization remain.

You should consider this situation moderately urgent. Prolonged exposure increases sensitivity and can escalate symptoms, particularly respiratory issues. The first step is to stop the moisture source—have an AC technician repair the leak immediately. For the mould itself, a professional inspection is strongly advised. DIY cleaning often aerosolizes spores, worsening the problem. A proper assessment will identify the full extent of contamination and the specific species, which determines the required remediation protocol. In Dubai's high humidity, controlling moisture is critical to prevent rapid regrowth after any clean-up.
