How to professionally test and treat mold from AC?« Back to Previous Page

A persistent cough in a child with visible mold growth near an AC vent warrants immediate professional assessment. The combination of high Dubai humidity and constant AC operation creates ideal conditions for mold to thrive inside walls from a leak, making surface cleaning insufficient.

For testing, engage a company with certified mold inspectors who use borescopes to see inside wall cavities and moisture meters to quantify the dampness. The most definitive method is air and surface sampling analyzed by an accredited microbiology lab, which identifies the mold species and concentration. This report is critical, as it dictates the remediation protocol and verifies the health risk level.

Treatment for this scenario is invasive. The AC leak must be repaired first. Remediation involves isolating the contaminated area with negative air pressure, removing affected drywall and insulation, and HEPA vacuuming all surfaces. Merely spraying a biocide is ineffective for hidden growth. Post-remediation verification testing is essential to confirm spore counts have returned to safe, ambient levels before the area is rebuilt.

Given the location in a child's bedroom and the existing health symptom, a DIY approach is not recommended due to the risk of cross-contamination and inadequate removal. Look for providers who follow IICRC S520 standards for mold remediation and can provide the full chain of documentation from inspection to post-clearance testing.
