Is AC leak causing mold and my cough in Dubai?« Back to Previous Page

Based on your description, it is highly probable that the black and green fuzzy growth under your carpet is mold, and it is almost certainly the cause of your respiratory symptoms. The pattern of your cough and stuffy nose resolving when you leave the contaminated bedroom is a classic indicator of a mold-related illness.

In Dubai's climate, where high external humidity meets year-round air conditioning, AC units are a primary source of mold problems. A leaking AC creates a constant source of moisture, and when this water saturates an organic material like carpet underlay, it creates an ideal breeding ground for mold colonies like Cladosporium (black) and Penicillium (green). The AC unit itself can then aerosolize these spores and circulate them throughout the room, which you inhale while sleeping.

For a case like this, a DIY approach is not recommended and can be hazardous, as disturbing the mold without proper containment will spread spores extensively. The fastest way to get it properly tested and remediated is to engage a professional environmental company.

We recommend you call Saniservice immediately at 800-MOLDS (800-66537) or email hello@saniservice.com. Their certified mold inspectors will conduct a comprehensive assessment, including moisture mapping and air quality testing to identify the exact species and spore count. They follow Dubai Municipality guidelines for remediation, which involves isolating the affected area with negative air pressure, safely removing the contaminated materials, and using industrial-grade HEPA filtration and antimicrobial treatments to ensure the mold is eradicated at its source and will not return. Addressing the root cause—repairing the AC leak—is a critical final step in the process.
