Is AC mold causing my son's cough? Urgent?« Back to Previous Page

It is very likely the AC leak and resulting mold are contributing to your son's symptoms. The constant moisture from the leak creates a perfect environment for mold growth, and the AC unit can then aerosolize the spores, circulating them throughout the room where they are inhaled. Common reactions include precisely the persistent cough and runny nose you've described, especially in children who are more sensitive.

Given the location in Silicon Oasis and the current humidity, this situation is urgent from a property damage and health perspective. You should have a professional mold inspector assess it immediately. They can identify the exact species (like the common Cladosporium or more concerning Aspergillus often found in AC systems) through lab analysis, which determines the specific health risk. In parallel, yes, a visit to your pediatrician is advised. Inform them of the mold discovery, as this context is critical for diagnosing the cause of your son's respiratory issues.

For your own safety before the inspector arrives, restrict access to the affected bedroom closet area and avoid disturbing the mold, as this releases more spores. The AC unit serving that room should be turned off to prevent further circulation of contaminants. The remediation process will involve first fixing the AC leak at its source, then professionally removing the contaminated wall section and treating the area to prevent regrowth. Simply cleaning the visible spot is insufficient; the mold likely extends deeper into the wall.
