Could AC mold smell be causing our persistent cough?« Back to Previous Page

That damp, moldy smell from your AC vent is very likely contributing to your family's persistent cough. In Dubai's climate, where ACs run constantly and humidity is high, this odor typically indicates microbial growth—mold or bacteria—inside the unit or ductwork, which then circulates irritants and allergens throughout your living space.

The timing after a maintenance service is a critical clue. Incomplete cleaning can dislodge existing growth, making the problem more apparent, or technicians may have missed contaminated components. For a villa in Jumeirah Park, the internal insulation of the ducts is a common culprit if it has gotten wet and was not properly dried or replaced.

You should first call the company that performed the last service for a re-inspection, specifically mentioning the new smell and health symptoms. However, for an independent assessment, you need a specialist who can conduct a visual inspection of the evaporator coil, drain pan, and accessible ductwork. The most definitive way to confirm the issue is through professional testing that includes air and surface sampling, with the samples analyzed by an accredited microbiology lab to identify the specific types and concentrations of mold present. This lab report is essential, as it moves from suspicion to evidence, showing exactly what you're dealing with.

Until resolved, consider running an air purifier with a HEPA filter in the main living area and ensure your villa's humidity levels are maintained below 60% to help reduce further growth.
