Could AC mold cause my child's bad cough?« Back to Previous Page

Based on your description, yes, it is highly probable that the microbial growth within your AC's chiller unit is a significant contributor to your child's persistent cough, especially if it worsens at night when the AC is likely running. The black, dusty gunk with a musty odor is a classic indicator of mold and bacterial biofilm, a common issue in the UAE's climate due to high humidity and dust.

When the AC runs, these spores and microbial fragments are aerosolized and blown directly into your living space. Children are particularly susceptible due to their developing respiratory systems. The cough worsening at night is a key symptom, as the child is inhaling the contaminated air for an extended period in an enclosed room.

The situation you've described in your Mirdif villa is serious and requires immediate professional attention. The leakage indicates a drainage problem, creating the constant moisture mold needs to thrive. Simply cleaning the filter is not enough; the entire internal evaporator coil (chiller), drain pan, and ductwork likely require a comprehensive hygienization process.

For your family's health, I strongly recommend you cease using that AC unit and schedule a professional inspection and remediation immediately. Our certified technicians use specialized tools like borescopes to assess the contamination deep within the system and employ EPA-approved biocides and steam cleaning to safely eradicate the growth.
