AC mold causing allergies: clean ourselves or call professional?« Back to Previous Page

Given the visible mold and your husband's symptoms, I would strongly recommend calling a professional company right away. The combination of a persistent water leak and black mold growth, especially in a sleeping area, elevates the risk beyond a simple DIY fix. His allergic reactions are a clear indicator that the mold is already affecting indoor air quality.

In Dubai's climate, AC units are a constant source of condensation, creating the perfect humid environment for mold to thrive inside the unit itself and spread spores through the ducts. What you see on the wall is likely just the tip of the iceberg; the internal components of the AC are almost certainly contaminated. DIY cleaning with bleach or vinegar only addresses surface stains and can aerosolize spores, potentially making the air quality worse and spreading the problem.

A professional inspection will identify the root cause of the leak and assess the full extent of the contamination, often using borescopes to see inside the AC. Proper remediation involves containing the area, using HEPA filtration to capture spores, and applying specialized biocides. The most critical step is a post-remediation verification test from an independent lab to confirm the spore count has returned to a safe level. This scientific, evidence-based approach is the only way to ensure the problem is truly resolved and not just hidden. For your family's health, starting with a professional assessment is the safest course of action.
