AC leak causing mold and health issues: how to fix?« Back to Previous Page

The situation you've described is a classic and serious concern here in Dubai. The combination of a condensate leak from your AC unit and our high ambient humidity creates a perfect breeding ground for mold, particularly the black spots you're seeing, which are likely Stachybotrys chartarum or Aspergillus. Your symptoms—morning headaches and nasal congestion—are textbook indicators of exposure to mycotoxins and mold spores, which the AC system can then circulate throughout the room.

The most effective response requires immediate action. For a small, visible patch (less than 1 square foot), you can carefully clean it with a solution of distilled white vinegar and water, wearing an N95 mask and gloves. However, this is only a surface treatment. The critical issue is that the moisture has likely penetrated the carpet underlay and possibly the wall structure behind it. This hidden contamination is the primary source of your health symptoms and will continue to recur if not addressed professionally.

To prevent recurrence, the AC leak must be repaired by a certified HVAC technician to stop the moisture source. Furthermore, given our climate, maintaining indoor humidity levels below 60% is crucial; this often requires using a dehumidifier in conjunction with your AC.

For a confirmed case like this, where health symptoms are present, a professional inspection is mandatory. DIY methods cannot assess the extent of hidden growth or the specific species present, which is vital for determining the correct remediation protocol as per UAE health and safety guidelines. We strongly recommend you cease using the affected AC unit and contact our certified team at Saniservice for a comprehensive inspection and hygienization plan.
