Can mold from my AC cause headaches and sore throat?« Back to Previous Page

The AC in my bedroom has been leaking a bit for the last month, and now I’ve found a patch of black and green mold on the wall behind the curtain. Since then, my throat has been constantly scratchy and I’ve been waking up with headaches. Could this mold be the cause of my symptoms, and what’s the proper way to get it cleaned here in Dubai?

Yes, mold from your AC can absolutely cause those symptoms. The scratchy throat and morning headaches are classic signs of exposure to mold spores and mycotoxins released into your bedroom's air. The continuous leak has created a persistently damp environment—ideal for mold growth in Dubai's climate, where high humidity and constant AC use can lead to condensation issues.

The proper cleanup is critical. For a patch caused by an AC leak, do not attempt to clean it with bleach or simple disinfectants. These often fail to penetrate porous materials like drywall and can just bleach the surface, leaving the root colony intact. The first step is to stop the source: have an HVAC technician repair the AC leak immediately.

For the mold itself, the approach depends on the extent. If the visible patch is small (e.g., less than one square meter), you might carefully clean the surface with a microfiber cloth and a dedicated mold-cleaning solution, ensuring you wear an N95 mask and gloves. However, since the mold is on an interior wall and you're already experiencing symptoms, the moisture has likely penetrated deeper into the wall cavity. In many Dubai villas and apartments, this hidden growth is a common problem.

The most reliable method is professional remediation. Reputable companies in Dubai will follow a process of containment (sealing off the area to prevent spore spread), removal of affected porous materials like contaminated drywall or insulation, HEPA vacuuming, and antimicrobial treatment. Afterwards, request a post-remediation verification test, ideally from an independent third party, to confirm the spore count in the air has returned to a normal level. This lab-certified result is your proof that the issue is resolved. Given your health symptoms, this investment in a proper, science-verified cleanup is strongly advised.
