Is my AC's black mold causing my sinus and cough?« Back to Previous Page

Yes, the black mold from your AC leak is very likely causing your sinus congestion and persistent cough. In Dubai's humid climate, AC units are prime breeding grounds for mold, and the species commonly found in these systems—like Cladosporium or Stachybotrys (black mold)—are known to cause exactly these respiratory symptoms through airborne spore exposure.

The constant moisture from a months-long leak creates an ideal environment for mold growth, not just in the unit but also in building materials like drywall. The wall behind your curtain, a dark and undisturbed area, is a classic spot for mold to flourish unnoticed. Your symptoms tracking with the leak's timeline strongly point to mold exposure as the culprit.

For a rental in JVC, responsibility is typically split. The landlord is almost always responsible for repairing the source of the problem—the malfunctioning AC unit itself and any structural damage to the property it has caused. You, as the tenant, are generally responsible for informing the landlord of the issue in writing and allowing access for repairs. Document the leak and mold growth with photos and dates immediately.

Before any cleanup, you need a professional inspection. DIY attempts can disturb the colony and spread spores. An inspector can identify the mold species and the full extent of the growth, which often spreads behind walls. They will provide a verified report, which is essential documentation for your landlord and for ensuring the remediation targets the root cause. Given the duration of the leak and your health symptoms, a proper assessment is strongly advised.
