Urgent: AC mold in Dubai making us sick?« Back to Previous Page

That damp smell and visible black spots around your AC vent are strong indicators of microbial growth, which is common in Dubai due to the constant AC use and high humidity. Your wife's morning congestion is a typical reaction, as mold spores and bacteria from the unit are being circulated directly into your bedroom air all night.

Given the symptoms and visible signs, a professional inspection is recommended. In Dubai's climate, AC units are prime locations for mold because the cold evaporator coils create constant condensation, providing the moisture mold needs to thrive. The issue isn't just the vent; the growth is likely inside the unit and the ductwork.

For a proper assessment, a certified inspector should take air and surface samples for lab analysis to identify the specific type and concentration of mold. This is crucial because while many types cause allergic reactions, some can be more problematic. They can also use a borescope to inspect inside the ductwork without causing damage.

Do not attempt to clean it with bleach or DIY sprays, as this can aggravate the spores and spread them further. Until it's inspected, you can run the fan on a continuous setting to help reduce moisture buildup inside the unit when it's not cooling.

Look for a provider that offers verifiable evidence of contamination with lab reports and uses methods like antimicrobial coating of the coils and ductwork, not just a superficial wipe-down, to prevent rapid regrowth.
