How to clean AC mold causing cough in kids?« Back to Previous Page

The small black spots around your AC vents are likely mold growth, which is common in Dubai due to our high humidity and constant AC use. The damp feeling and persistent cough in your kids are strong indicators that the unit's evaporator coil and drip pan—the main sources of condensation and mold—need a deep clean.

For a thorough cleaning, turn off the AC's power. Remove the vent covers and wash them with a mild detergent. Wipe down the accessible interior surfaces with a diluted vinegar or specialized AC coil cleaner. However, this surface cleaning often doesn't reach the contaminated evaporator coil and drain pan inside the unit, which is the core of the problem.

The most effective solution is a professional deep cleaning service. They use high-pressure steam and EPA-approved disinfectants to clean the entire internal system, including the coil and drain line, which is crucial for stopping the cycle of dampness and mold growth. This is not a standard AC gas-top-up service; it requires specific expertise.

Given the health symptoms, I would recommend a professional mold inspection first. They can use a borescope to inspect the internal coil and may suggest an air quality test to identify the mold species. This is important as some types commonly found in AC systems can exacerbate respiratory issues. In many cases, a proper deep clean of the entire AC system, combined with managing indoor humidity levels, can significantly reduce the problem and improve your indoor air quality.
