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

Yes, the mold from your AC leak could very likely be the cause of your persistent cough and headaches. The black, fuzzy patches indicate active growth, and the continuous leakage has created a consistently damp environment—exactly what mold needs to thrive. In Dubai's climate, where we rely on AC year-round, such leaks often lead to high humidity and condensation indoors, accelerating mold problems.

The symptoms you describe—dry cough and headaches—are classic indicators of mold exposure, often resulting from the mycotoxins and spores it releases into the air you breathe. This is especially common when the mold is in a bedroom, as you're exposed to it for prolonged periods during sleep.

The proper way to address this is not a simple cleaning. For a case of this duration and with visible wall contamination, a professional inspection is strongly advised to assess the full extent, including inside the AC unit and potentially the wall cavity. Disturbing it incorrectly can aerosolize a massive amount of spores, drastically worsening your indoor air quality and symptoms.

In Dubai, reputable remediation companies should follow strict protocols: they will isolate the area with containment barriers, use HEPA filtration devices to clean the air, safely remove the contaminated materials, and treat the area with antimicrobial solutions. The most critical step is identifying and repairing the source of the moisture—in this case, the AC leak—otherwise, the mold will return quickly. Always request verifiable before-and-after air quality test results from an independent lab to confirm the environment has been returned to a safe state.
