Is AC leak causing mold and our cough? How urgent?« Back to Previous Page

A persistent AC leak in Dubai's climate almost certainly leads to mould growth, and your husband's symptoms are a common reaction. The high humidity here, combined with condensation from a faulty unit, creates the perfect damp environment for mould spores to colonise. The black spots on the wall are a visible confirmation of a moisture problem that needs immediate attention.

Given the symptoms and visible growth, this is an urgent issue. You should stop using that AC unit and sleep in another room until it is professionally inspected and remediated. Continuous exposure to mould spores from the air conditioner can exacerbate respiratory issues, leading to prolonged allergy-like symptoms or sinus infections.

For a situation like this, a simple cleaning won't suffice. The leak must be repaired first to eliminate the moisture source. Then, the mould on the wall needs proper remediation to remove the colony and prevent spores from spreading. Finally, the AC unit's internal evaporator coil and drip pan require a thorough microbiological clean to address the contamination at its source.

A professional inspection will identify the exact mould species and the extent of the problem. In Dubai, look for a provider that uses lab analysis to guide their remediation process, ensuring the solution is targeted and effective, not just superficial. This approach verifies the mould is truly gone and the air quality is safe before you resume using the room.
