Is AC mold causing my husband's cough?« Back to Previous Page

Based on your description, it is highly probable that the black spots around your AC vent are microbial growth, and your husband's persistent respiratory symptoms are very likely connected. The continuous moisture from the leaking AC unit creates an ideal environment for mold spores, which are ubiquitous in Dubai's humid climate, to colonize. When the AC system operates, it can aerosolize these spores and mycotoxins, distributing them throughout the room where they are inhaled.

This situation should be treated with urgency. Persistent coughs and nasal congestion are classic indicators of mold exposure. Given that the contamination is within the AC system—a central distribution point for air—it is a 'call someone tomorrow' scenario. Allowing it to continue over the weekend significantly increases exposure risk and potentially allows the colony to spread further into the ductwork.

The UAE's hot and humid climate forces AC systems to run year-round, leading to significant condensation. If drainage lines become blocked or units are not regularly maintained, this moisture accumulation becomes a persistent problem. DIY cleaning of visible spots is not recommended, as it often disturbs the colony without addressing the root moisture issue or contamination within the ducts, potentially making the airborne spore count worse.

A professional inspection is absolutely necessary. Certified specialists, like our team at Saniservice, will conduct a thorough assessment, including air and surface sampling to identify the species and concentration of mold present. This evidence-based approach is crucial for determining the correct remediation protocol. We will identify and rectify the source of the moisture, then perform a comprehensive hygienization of the affected areas and the AC ductwork to ensure the environment is safe and healthy.
