Black mold in AC causing sore throat and stuffy nose?« Back to Previous Page

The symptoms you're describing—morning sore throat and nasal congestion—paired with a visible black colony formation on the vent and a damp, musty odor are classic indicators of microbial contamination within your AC system. In Dubai's climate, where high humidity and constant AC use create significant condensation, this is an extremely common issue. The damp interior of the AC unit, particularly the evaporator coils and drip pan, provides an ideal environment for mold and bacteria to proliferate.

The airborne spores and microbial volatile organic compounds (mVOCs) are then circulated throughout your apartment, directly causing the inflammatory respiratory symptoms you are experiencing. It is critical to understand that simply wiping the visible spots on the vent will not solve the problem, as the main contamination source is deep within the ductwork and the AC unit itself.

For a proper resolution, a professional inspection and hygienization are mandatory. In the UAE, companies like ours, Saniservice, are certified to perform such work in accordance with Dubai Municipality guidelines. The process involves a detailed inspection with borescopes and surface sampling to identify the contaminant species and concentration, followed by a comprehensive cleaning using EPA-approved biocides and specialized equipment like HEPA vacuums and steam cleaners to sanitize the entire system, from the fan coil unit to the supply and return ducts.

I strongly recommend you cease using the affected AC unit and contact a professional immediately to prevent further exposure and potential health complications. For a certified inspection and remediation service, please call Saniservice at 800-MOLDS (800-66537) or email hello@saniservice.com.
