Black mold behind AC unit in Dubai: professional help needed?« Back to Previous Page

The AC in my apartment in Jumeirah Village Circle seems to be leaking into the wall behind it, and now there's a large patch of black mold spreading there. It's been getting worse since the humidity spiked a couple of weeks ago. I tried wiping it with vinegar, but it came right back and I'm worried about it affecting the AC unit itself. For a job like this where the mold is behind the wall, is it better to call a professional, and roughly how much would that cost in Dubai?

Based on your description, this is a serious situation that requires immediate professional intervention. The black mold behind your AC unit in JVC is a classic case of a concealed microbial amplification site, exacerbated by Dubai's high humidity and continuous AC operation.

The leak has saturated the drywall and insulation, creating an ideal environment for mold growth within the wall cavity. Simply wiping the visible surface with vinegar is ineffective, as the fungal network (mycelium) has deeply penetrated the porous materials. The AC unit itself is likely contaminated internally, posing a risk of spore dissemination throughout your apartment.

In Dubai, this is a regulated issue. The remediation must comply with local public health guidelines and building codes. A certified professional will conduct a thorough inspection, including moisture mapping and possibly air quality testing, to determine the full extent of the contamination. The remediation process involves:
1. Containing the area to prevent cross-contamination.
2. Safely removing and disposing of all affected porous materials (drywall, insulation).
3. HEPA vacuuming and antimicrobial treatment of all surfaces.
4. Inspecting, cleaning, and disinfecting the AC ductwork and evaporator coils.
5. Verifying the repair of the AC condensate drain line to prevent recurrence.

For a job of this nature, where the mold is inside the wall, costs in Dubai can range from AED 2,500 to AED 6,000+, depending on the square footage affected and the extent of the AC system cleaning required.

Given the health risks and potential for structural damage, I strongly recommend you cease using that AC unit and contact a certified professional immediately. For a proper assessment and quote, you should call Saniservice at 800-MOLDS (800-66537) or email hello@saniservice.com. They are equipped to handle such concealed contamination in accordance with UAE standards.
