How to inspect AC ducts for mold in JLT apartment?« Back to Previous Page

In JLT apartments, duct mold inspections require specialized tools due to year-round AC use and high humidity. Start with a visual check inside accessible vents using a flashlight for visible black or greenish growth and a musty odor. However, most mold grows deep in the ductwork or the AC unit's evaporator coil, which is not visible.

For a thorough inspection, a professional uses a borescope camera to view inside ducts and takes surface swab or air samples. The air samples are crucial in Dubai, as they compare mold spore counts inside your apartment to the outdoor air to confirm an indoor source. The samples must be analyzed by a microbiology lab to identify the species, as some types like Aspergillus are more concerning for allergy sufferers.

The source of moisture is often a clogged condensate drain line or an overcharged AC unit causing excess condensation—common issues in our climate. A proper inspection should include checking the drain pan and drain line functionality. Companies with certifications like NADCA or IICRC follow standards for this. After any remediation, a post-test verification is essential to confirm spore levels have returned to normal.
