Who to call for moldy AC in Dubai?« Back to Previous Page

Your symptoms and the black, powdery substance are strong indicators of a microbial issue, likely mold, in your AC system. This is a common problem in Dubai due to high humidity and condensation buildup inside AC units that run year-round.

You should contact a professional indoor environmental company that specializes in mold inspection and AC cleaning. Look for a provider that offers a full diagnostic process, not just a superficial clean. A reputable company will first conduct an inspection, often using a borescope to examine the inaccessible internal evaporator coils and drain pan—where the damp smell originates. They should take a sample of the black substance for lab analysis to confirm if it's mold and identify the species, which determines the appropriate remediation protocol.

The cleaning itself must be comprehensive. Avoid companies that just spray disinfectant and leave. Proper remediation involves applying a specialized, non-toxic biocidal foam to the coils to kill microbial growth, followed by steam cleaning or high-pressure washing to remove the debris and any biofilm. Finally, the system should be treated with a protective coating to inhibit future growth. Always request before-and-after evidence, such as photos of the clean coils and copies of the lab results, to verify the work was done correctly.

For severe, recurring issues, a full duct cleaning might be necessary to remove contaminated dust from the entire system.
