How to professionally check and clean moldy AC in Dubai?« Back to Previous Page

The damp smell at startup is a classic sign of microbial growth, often from condensation buildup in the AC's evaporator coils or drip pan—a common issue in Dubai's humid climate where ACs run year-round.

For a professional check, hire a company that provides a visual inspection with a borescope for the ductwork and a surface sample from the evaporator coil for lab analysis. This identifies the mold type and concentration, which is crucial as some species are more problematic than others. Avoid companies that only do a visual check or offer "sanitizing" without diagnostics.

Effective cleaning must address the source. A proper remediation involves dismantling the AC unit to access and clean the coil and drip pan with EPA-approved biocides, followed by a full duct cleaning using HEPA-filtered vacuours. To prevent recurrence, the company should verify that the drain line is clear and the unit is properly insulated to reduce condensation.

For lasting results, the cleaning must be paired with a post-remediation verification (PRV) test—a second round of lab sampling to confirm spore counts are back to acceptable levels. This is the only way to know the job was done correctly. Many Dubai landlords or building management will cover this cost if the issue is reported, as it falls under property maintenance.
