Could AC mold be causing my family's cough and fatigue?« Back to Previous Page

Based on your description, it is highly probable that microbial growth in your AC chiller unit is the source of your family's health issues. The black speckled substance around the vent is a classic visual indicator of mold colonization, which is alarmingly common in the UAE's climate due to high humidity levels promoting condensation within AC systems.

When a chiller unit leaks, it creates a perpetually damp environment—the perfect breeding ground for mold spores. These spores are then circulated directly into the bedroom's air every time the AC operates. Continuous inhalation of these contaminants can cause persistent respiratory irritation, manifesting as a non-stop cough, congestion, and systemic inflammation that leads to fatigue. Children are often more susceptible to these effects.

This is a serious indoor air quality concern. While DIY cleaning of the visible vent is possible, it addresses only a fraction of the problem. The main contamination is inside the ductwork and on the cooling coils of the chiller unit itself, which requires professional-grade equipment and biocides to address effectively and safely.

For a definitive diagnosis and a permanent solution, a professional inspection and hygienization are non-negotiable. Our certified technicians use borescopes to inspect deep within the ducts and conduct air quality tests to identify the spore types and concentration levels. We then perform a comprehensive HVAC hygienization process that eliminates the contamination at its source.
