Is our AC leak causing mold-related health symptoms?« Back to Previous Page

The symptoms you're describing—morning congestion and headaches that improve when you leave—are strongly indicative of mold-related illness, especially given the visible growth and AC leak. Dubai's high humidity and constant AC use create a perfect environment for mold, as condensation from a leaking unit provides the moisture it needs to thrive behind walls and furniture.

Your first step is to stop the moisture source. Have a certified HVAC technician repair the AC leak immediately. For the visible mold, do not attempt to clean it yourself, as disturbing it can release a high concentration of spores into your air. The spread behind the wardrobe suggests a larger infestation is likely hidden within the wall cavity.

You need a professional mold inspection to assess the full extent. In the UAE, look for a provider that uses a combination of visual assessment, moisture mapping, and air/o-surface sampling. The critical part is that the samples are analyzed by an accredited microbiology lab to identify the species, as this determines the health risk and required remediation protocol. This lab report is your evidence and guide for proper removal.

Remediation involves isolating the area, using HEPA filtration to capture airborne spores, safely removing contaminated materials, and treating the area with antimicrobial solutions. Simply wiping the surface is ineffective for a persistent leak. After remediation, a post-test verification is essential to confirm spore counts have returned to acceptable indoor levels.
