Black AC dust causing headaches; cost to clean system?« Back to Previous Page

The AC in my apartment in Jumeirah seems to be spreading a black, powdery dust around the living room, and we've been getting headaches. I tried wiping the vents but it came back in a couple of days. Is this the "long mold" I've heard about, and if so, roughly how much would it cost to get a professional company to properly clean the entire AC system?

Based on your description, that black, powdery dust is a classic sign of microbial growth within your AC system, a very common issue here in Dubai due to our high humidity and condensation in ductwork. What you're likely seeing is not a specific "long mold" but a combination of mold spores, soot, and other allergens that have accumulated in the damp, dark environment of your AC unit and ducts. The recurring headaches are a significant red flag, strongly indicating poor indoor air quality that needs immediate attention.

A simple wipe-down of the vents is ineffective because the contamination source is deep within the system. The entire unit, including the evaporator coils, drip pan, and air ducts, requires a professional hygienization process. This involves specialized equipment like high-powered vacuum collection units, rotary brush systems, and antimicrobial coating to prevent regrowth, all performed by certified technicians.

For a standard apartment in Jumeirah, the cost for a comprehensive AC cleaning and sanitization service can range from AED 1,200 to AED 2,500+, depending on the number of units and the severity of the contamination. However, we strongly recommend a professional inspection first to accurately assess the extent of the problem and provide a firm quotation. This is not just a cleaning issue; it's a health concern.
