How to test and clean moldy AC ducts in Dubai?« Back to Previous Page

Stop the AC unit immediately to prevent further spore dispersal. The combination of high humidity and constant AC use in Dubai creates ideal conditions for mold growth inside ducts, especially when condensation forms.

For a situation involving visible growth and respiratory symptoms, a professional inspection is strongly recommended over DIY testing. A proper assessment involves a visual inspection with a borescope to see inside the ductwork and, crucially, surface and air sampling. These samples must be analyzed by an accredited microbiology lab to identify the specific mold type (e.g., Cladosporium, Stachybotrys) and its concentration in the air. This lab report is essential; it confirms the problem's scope and verifies that the chosen remediation method was effective afterward.

The cleaning process itself must be containment-based. Reputable companies will seal off the vents with plastic sheeting and use negative air pressure machines to prevent cross-contamination to other parts of your villa. They will then use HEPA-vacuuming and antimicrobial treatments on all internal duct surfaces.

Always request before-and-after lab air quality test results from any company you contact. This is the only way to objectively verify that the indoor environment has been restored to a safe state and that the cleaning was not just superficial.
