AC Leak Causing Mold: Health Risk and Professional Test Needed?« Back to Previous Page

The AC in our apartment in Jumeirah has been leaking a bit, and now I've noticed black spots along the wall behind the sofa. For the last couple of weeks, my husband and I have been waking up with stuffy noses and scratchy throats that clear up once we get to the office. How quickly can something like this become a serious health issue, and should we get a professional test done or just clean it ourselves?

Based on your symptoms clearing up when you leave the apartment, the black spots are very likely the source of your irritation. The persistent dampness from an AC leak creates an ideal environment for mold in Dubai's climate, where high humidity prevents it from drying out naturally.

Health risks escalate the longer the exposure continues. For most healthy adults, initial symptoms are irritation like you're experiencing. However, prolonged exposure can lead to more persistent respiratory issues, sinus infections, and worsened allergies. The transition from minor to more significant health impacts can happen over several weeks to a few months of continuous exposure.

Cleaning visible spots yourself with a detergent solution is a temporary measure, but it rarely addresses the root cause. The leak must be repaired first, and mold can penetrate porous materials like drywall and insulation, which requires professional remediation to remove completely.

Given the symptoms are already apparent, a professional inspection is strongly recommended. They can identify the exact mold species through lab testing, assess the full extent of the hidden growth behind the wall, and provide a protocol for safe, effective removal that includes containment and air scrubbing to prevent spores from spreading during cleanup. This is the most reliable way to resolve the health symptoms and protect your property.
