Is our AC leak causing mold and making us sick?« Back to Previous Page

Based on your description, it is highly probable that the black spots are microbial growth, specifically mold, caused by the continuous moisture from the AC leak. The climate in Dubai, with its high ambient humidity, creates an environment where condensation from an improperly draining AC unit provides the perfect breeding ground for mold.

The symptoms you and your husband are experiencing—persistent stuffy nose and sore throats—are classic indicators of exposure to mold spores and microbial volatile organic compounds (mVOCs). These biological contaminants become aerosolized and are circulated by the AC system, leading to the respiratory issues you describe.

This is a serious indoor air quality issue. In the UAE, properties, especially in humid coastal areas like Jumeirah, are highly susceptible to such problems. A professional inspection is not just recommended; it is essential. DIY cleaning is insufficient as it only addresses surface growth and not the spores embedded within the wall or the contamination within the AC ductwork itself, which requires specialized equipment and EPA-approved antimicrobials for proper remediation.

You need a certified mold inspector to conduct a thorough assessment, including moisture mapping and possible air quality testing, to determine the full extent of the contamination. The remediation process will involve stopping the water intrusion at its source (fixing the AC drain line), followed by the containment, removal, and hygienization of affected materials.

For a definitive diagnosis and a comprehensive remediation plan, I strongly advise you to contact a professional service immediately. You can reach our certified specialists at Saniservice for a consultation at 800-MOLDS (800-66537) or via email at hello@saniservice.com.
