Can black mold from AC cause headaches and need professional?« Back to Previous Page

Yes, black mould from an AC leak can absolutely cause persistent headaches. The mycotoxins and volatile organic compounds (VOCs) released by active mould growth are known irritants to the nervous system, and headaches are a very commonly reported symptom, alongside sinus congestion and fatigue. Your husband's symptoms coinciding with the visible growth strongly suggest a connection.

In Dubai's climate, this is an urgent issue. The constant high humidity provides a perfect environment for mould to thrive, especially in enclosed, damp spaces like a closet with a leaking AC unit. Bleach is not a recommended solution here; it is mostly water, which can feed the mould root system hidden inside the drywall, and its fumes are hazardous in an indoor environment. Surface cleaning will not address the colony growing within your wall.

This situation requires a professional assessment. The leak must be fixed first to stop the moisture source. A reputable remediation company will conduct a thorough inspection, often using a borescope to see inside the cavity, and will take air and surface samples for lab analysis to identify the mould species and concentration. Remediation involves isolating the area, removing contaminated porous materials like damaged drywall, and using professional-grade HEPA filtration to clean the air. For a case involving health symptoms and concealed growth, a DIY approach carries a high risk of making the contamination worse.
