Is AC mold causing our headaches and stuffy noses?« Back to Previous Page

Yes, absolutely. Based on your description, the symptoms you and your husband are experiencing are highly consistent with exposure to microbial growth, specifically from your AC system. The black, powdery substance is a classic visual indicator of mold colonization, often of the Cladosporium or Stachybotrys (black mold) varieties, which are common in the UAE's humid climate, especially when moisture from an AC leak is present.

When the AC unit operates, it aerosolizes these spores and mycotoxins, distributing them throughout the room. Inhaling these contaminants, especially over hours of sleep in a closed environment, directly causes the inflammatory responses you describe: sinus congestion, headaches, and general malaise. The fact that symptoms subside when you leave the contaminated environment is a very strong diagnostic clue.

Regarding cost in Dubai, it's a two-part process. First, a professional inspection and air/swap test to identify the species and spore count is crucial for a proper remediation plan. This typically starts from AED 800-1,500 for a single unit/room. The remediation (cleaning) cost itself depends on the extent of contamination within the ductwork and the AHU (Air Handling Unit). For a single unit with localized growth, you could be looking at AED 2,000 - 4,000+ for a comprehensive hygienization that includes anti-microbial fogging and coil cleaning, not just a superficial wipe-down. DIY cleaning is not advised as it often disperses spores further.

Given the health implications and the potential for the problem to be more extensive inside the ducting, a professional assessment is strongly recommended. We can provide a precise quote after an on-site evaluation.
