How to clean and test AC ducts for mold?« Back to Previous Page

In Dubai's climate, AC ducts are prime locations for mold due to constant condensation from high humidity. For a situation with visible growth and health symptoms, a professional inspection is strongly recommended over DIY cleaning, as improper methods can disperse spores throughout your home.

A reputable mold remediation company will first conduct an inspection, often using a borescope to see inside ducts, and should take surface or air samples for lab analysis to identify the species. The cleaning itself is a contained process: technicians will seal the system, use HEPA-filtered vacuums to extract debris, and mechanically clean all interior surfaces with specialized tools. Simply spraying a disinfectant is ineffective and can leave mold roots intact.

After remediation, post-cleaning verification testing is essential to confirm spore counts have been reduced to acceptable levels. Look for providers who are certified by organizations like the IICRC and can show you documented before-and-after lab results, not just photos of clean vents. For buildings in older areas like Bur Dubai, ensuring the system's drain pans and insulation are also addressed is key to preventing quick regrowth.
