Is the AC mold making my husband sick?« Back to Previous Page

The AC in our Jumeirah villa has been leaking a little bit in the master bedroom closet for a couple of months, and now we’ve found black spots on the back wall. My husband has had a persistent stuffy nose and a weird cough that just won’t go away since it started. Could this mold be the reason he’s been feeling so unwell, and what’s the first step we should take to deal with it?

Yes, the mould from your AC leak is very likely causing your husband's persistent respiratory symptoms. The constant moisture from a leak in a confined space like a closet creates an ideal environment for mould growth, and the resulting spores are then circulated by the AC unit. Symptoms like a chronic stuffy nose, cough, and throat irritation are classic indicators of mould exposure, especially in individuals who may be more sensitive.

The first step is to stop the moisture source. You must have the AC unit inspected and repaired by a qualified HVAC technician to fix the leak permanently. Simply cleaning the visible mould will not solve the problem if the water intrusion continues.

For a situation that has persisted for months, a professional mould inspection is strongly recommended. The visible black spots are often just the tip of the iceberg; mould can grow inside the wall cavity and within the AC system itself. An inspector can use moisture meters and thermal imaging to find the full extent of the damage and take air or surface samples for lab analysis to identify the specific mould type, which determines the appropriate remediation protocol.

In Dubai's climate, where we rely on AC year-round and high humidity promotes condensation, this is a common issue. Prompt, professional remediation is key to restoring your indoor air quality and alleviating health symptoms. Look for a provider that offers detailed documentation and post-remediation verification testing to confirm the environment is safe.
