AC smell and black specks: Professional cleaning needed in Dubai?« Back to Previous Page

The AC in our apartment in Jumeirah seems to be blowing out a weird, damp smell, and now I’ve spotted some black speckles around the air vent in the master bedroom. We run the AC constantly, especially over the last few humid months, and I’m worried it’s spread inside the ducts. Is getting the entire system cleaned by a professional a massive job, and what’s the typical cost in Dubai for something like that?

Based on your description of a damp smell and visible black speckles around the AC vent in Jumeirah, it is highly probable that you are dealing with microbial growth, likely mold, within your air conditioning system. This is a common issue in Dubai due to the extreme humidity and the year-round reliance on AC, which creates significant condensation—an ideal environment for mold proliferation inside ducts and on cooling coils.

A professional cleaning is not just recommended; it is essential. The job's scale depends on the extent of contamination. It involves a comprehensive process: isolating the HVAC system, using HEPA vacuuming to remove particulate matter, and employing antimicrobial agents to disinfect the evaporator coils, drain pans, and ductwork. For visible growth at the vent, the contamination is likely more widespread inside. This is not a task for general cleaners; it requires certified mold remediation specialists.

Costs in Dubai for a full AHU and duct cleaning can vary based on the system's size (tonnage) and contamination severity, but typically range from AED 1,500 to AED 4,000 for a standard villa or apartment system.

We strongly advise against attempting any cleaning yourself, as improper methods can aerosolize spores and spread the contamination further. The first step is a professional inspection to assess the extent of the problem. Our certified technicians can conduct this assessment, provide a precise scope of work, and a fixed-quote price.
