Dealing with AC mold smell and black spots?« Back to Previous Page

Yes, this is a job for a professional. The damp smell and recurring black spots indicate active mold growth inside your AC unit and ductwork, which is common in Dubai due to high humidity and constant AC use creating condensation. Bleach only addresses surface spots you can see, not the colony feeding on moisture and dust within the system.

You should expect a proper remediation to involve several steps: isolating the vent area to prevent spores spreading, removing and cleaning the contaminated vent covers, then accessing and vacuuming the internal evaporator coils and drip pan with HEPA equipment. The ductwork leading to that vent may also need cleaning. The entire process for a single unit typically takes a few hours.

For cost, simple vent and coil cleaning is a more standard service. However, with visible regrowth, the scope is likely larger. Pricing is not fixed and depends entirely on the infestation's severity and the system's accessibility. You can expect a significant difference in cost between a basic clean and a full remediation that includes antimicrobial treatment. Always request a detailed assessment and quote first; a reputable company will provide this on-site after inspecting the internal unit before any work begins. They should also be able to explain the process and show relevant certifications for mold remediation.
