Is AC mold causing our cough and fatigue?« Back to Previous Page

Based on your description, it is highly probable that the microbial growth (the black and green fuzzy patch) discovered under your carpet is the direct cause of your persistent dry cough, congestion, and fatigue. This is a serious indoor air quality issue, especially common in Dubai due to our climate.

The scenario you describe is a classic case of AC-induced mold growth. The leaking AC unit creates a constant source of moisture. When this water saturates an organic material like carpet underlay or concrete screed, it creates an ideal breeding ground for mold. The spores and microbial volatile organic compounds (mVOCs) produced by these colonies become aerosolized and are circulated every time the AC fan operates, leading to chronic respiratory irritation and systemic symptoms like fatigue.

In the UAE, the combination of high external humidity and year-round AC use makes condensation and leaks a frequent problem. The damp, dark environment of an AC drip pan or a water-damaged carpet is a perfect habitat for species like Aspergillus and Cladosporium, which can cause the symptoms you are experiencing.

A DIY approach is not recommended. Disturbing the mold by lifting the carpet can cause a significant release of spores, exacerbating your exposure. Proper remediation requires isolating the area, using HEPA filtration to capture airborne particulates, and the professional application of antimicrobial agents.

I strongly advise you to cease using that AC unit and contact a professional environmental inspector immediately. Our certified team at Saniservice can conduct a thorough inspection, including air and surface sampling to identify the species and concentration levels, and then execute a full remediation protocol to make your home safe again.
