Urgent: Is mold in AC affecting our health?« Back to Previous Page

Yes, what you're describing is almost certainly a mold issue and it is very likely affecting your health. The constant stuffy noses are a classic symptom of exposure to airborne mold spores from a contaminated AC system, which acts as a perfect distribution network throughout your home.

Given Dubai's high humidity and year-round AC use, the conditions inside your unit are ideal for mold growth. The condensation that forms on cooling coils never fully dries, creating a perpetually damp environment. The black and green spots you see are the visible colonies, but the real concern is the invisible spores being blown into your living space.

This situation warrants prompt professional attention. While not every mold type is highly toxic, all molds can cause allergic reactions and respiratory irritation, especially in children, the elderly, or those with asthma. The persistent symptoms you describe indicate the exposure is already significant.

Do not attempt to clean this yourself with store-bought sprays, as this can aerosolize the spores and worsen the problem. A proper remediation involves isolating the unit, using HEPA vacuuming and antimicrobial treatments on the coils, drip pans, and ductwork to address the source. Crucially, the cleaning must be verified with before-and-after testing to confirm the spore count in your air has returned to a safe level. For a situation this advanced, an inspection and professional remediation is the most effective path to restoring your indoor air quality and health.
