How to treat and prevent mold from AC dampness?« Back to Previous Page

The dampness and black spots indicate your AC is likely producing excess condensation, which is common in Dubai's humidity. First, treat the existing mold with a solution of one part white vinegar to three parts water, scrubbing the affected areas. For porous surfaces like drywall, cutting out and replacing the material may be necessary if the growth is extensive.

To prevent recurrence, the AC unit itself must be addressed. Excess condensation often stems from a clogged drain line, low refrigerant, or an undersized unit struggling in the summer heat. A thorough professional service should clean the drain pan and line, check refrigerant levels, and ensure the evaporator coil is clean. For villas in areas like Al Barsha, ensuring the external AC condenser has proper airflow is also critical.

Long-term prevention requires managing indoor humidity. Run your AC consistently to maintain a stable temperature and reduce condensation cycles. Consider using a dedicated dehumidifier in your son's room, especially during the more humid summer months. Improve ventilation by occasionally opening windows when the external humidity is lower, typically during the drier winter months.

For persistent issues, a professional inspection can identify if the mold has spread inside the AC unit or ductwork, which requires specialized cleaning. They can also use moisture meters to find hidden dampness in walls. Verifiable before-and-after testing, like air or surface samples analyzed by an accredited lab, provides the only concrete proof the problem has been resolved.
