AC mold cleaning needed or DIY for JVC apartment?« Back to Previous Page

The damp smell and black spots indicate active microbial growth, likely due to condensation in your AC unit—a common issue in Dubai's humid climate where ACs run year-round. Your husband's symptoms are consistent with exposure to mold spores circulating from the system.

Cleaning visible spots with a dilute bleach solution can address surface mold on the vent cover, but it will not reach the contamination inside the AC unit or ductwork. This is a temporary fix, and the smell and spots will likely return.

For a persistent issue like this, a professional inspection is recommended. They use borescopes to inspect internal coils and plenums, which are the true source of the problem. Proper remediation involves specialized biocides and cleaning of the entire system to stop the cycle of contamination. The cost for a one-bedroom apartment is typically based on the number of AC units (fan coils) rather than room count, so requesting an assessment for your specific system is the best approach.
