Is black mold in our AC closet a health risk?« Back to Previous Page

Black mould in an AC closet is a definite health risk, especially given your husband's symptoms of a stuffy nose and itchy eyes. These are classic signs of mould exposure, which irritates the respiratory system and can worsen allergies. The risk is higher for individuals with asthma or weakened immune systems.

In Dubai's humid climate, the constant condensation from AC units creates a perfect environment for mould growth, particularly in enclosed, poorly ventilated spaces like closets. The unit itself may be leaking or have a clogged drain line, perpetuating the dampness.

This is not merely a cosmetic issue. Under the Dubai Rental Law, the landlord is responsible for addressing issues that affect the health and safety of tenants and the structural integrity of the property, which includes fixing the source of moisture causing the mould. You should formally notify your landlord in writing about the problem, as they are obligated to rectify the underlying cause, such as repairing the AC unit or fixing insulation.

While you can clean visible mould with a vinegar or diluted bleach solution, this only addresses the surface growth and not the root moisture problem. A temporary DIY clean might provide short-term relief but will not stop it from returning. For a persistent issue with health symptoms, a professional inspection is recommended to identify the exact moisture source and the mould species. This provides concrete evidence for your landlord and a clear remediation plan.
