Is black mold from AC making us sick?« Back to Previous Page

The AC in our bedroom has been leaking a little for the past couple of weeks and we’ve just discovered a patch of black mold on the wall behind the headboard. My husband has started waking up with a stuffy nose and a headache every morning, which clears up after he's at work. We're in an older building in Deira and I'm worried this is making him sick. How urgently do we need to get this professionally cleaned, is this something we can handle ourselves with cleaners from ACE, or should we even consider staying somewhere else until it's fixed?

Based on your description, it is highly probable that the black mold growth from the AC leak is the cause of your husband's morning sinus congestion and headaches. The symptoms clearing up after leaving the contaminated environment is a classic indicator of mold-related illness.

In the UAE's humid climate, AC systems are a primary source of condensation and subsequent mold growth if not properly maintained. The black patch you've discovered is likely Stachybotrys chartarum or Aspergillus niger, both of which are known to produce mycotoxins and volatile organic compounds (VOCs) that cause the inflammatory responses you've described. This is not a simple surface contaminant; the moisture has likely penetrated the wall's structure, creating a reservoir for hidden growth.

This situation requires immediate professional attention. DIY cleaning with solutions from ACE is strongly discouraged. Off-the-shelf chemicals are ineffective at penetrating porous materials like drywall and can actually exacerbate the problem by releasing a higher concentration of spores and mycotoxins into the air without addressing the root moisture issue. Furthermore, improper remediation can violate Dubai Municipality's public health and housing regulations regarding fungal contamination.

I recommend you cease using the affected AC unit immediately and consider temporary relocation, especially for anyone with respiratory sensitivities, until a full assessment is completed. The leak must be repaired by a certified HVAC technician first to eliminate the moisture source.

For the mold itself, a professional inspection and remediation is essential. Our certified team at Saniservice uses advanced techniques like thermal imaging to map the full extent of the contamination, followed by engineered controls (negative air pressure, HEPA filtration) to safely remove the toxic material without cross-contaminating your home. Do not delay, as prolonged exposure poses significant health risks.
