AC leak causing wall mold and sickness: professional help needed?« Back to Previous Page

The AC leak is almost certainly the source of your problem, and the symptoms you describe are consistent with mold exposure. In Dubai's climate, constant AC operation creates significant condensation; any leak introduces moisture directly into building materials, creating an ideal environment for mold growth within 24-48 hours.

Do not attempt to clean this yourself over the weekend. Disturbing the mold by scrubbing can aerosolize spores, potentially worsening your husband's respiratory issues and spreading the contamination to your HVAC system. The priority is stopping the moisture source. You need an AC technician to repair the leak immediately.

For the mold itself, professional assessment is strongly advised. The splotchy pattern and its location inside a bedroom, coupled with health symptoms, indicate it has likely spread behind the wall. A proper inspection involves moisture meters and, if necessary, lab analysis to identify the species, as "black mold" is a broad term covering both common allergenic types and the more concerning Stachybotrys. This diagnosis is key to determining the correct remediation protocol, which for wall cavities typically requires controlled demolition, HEPA vacuuming, and antimicrobial treatment to prevent recurrence. Look for a provider that can show documented before-and-after testing to verify the environment has been returned to a safe state.
