How to inspect my villa's AC for hidden mold?« Back to Previous Page

Start with a visual inspection of all supply and return vents for any visible black, green, or grey speckling. The persistent damp smell you describe is a significant indicator of microbial growth inside the ductwork or the AC unit itself, which is common here due to the constant condensation in our humid climate.

For a villa, the most thorough approach is a professional inspection that includes three key steps. First, an inspection of the evaporator coils and drip pans inside the AC air handling unit, as these are prime locations for hidden mold due to constant moisture. Second, a borescope inspection of the ductwork to visually confirm growth deep inside the walls or ceilings. Third, and most critical, is surface and air sampling to be analyzed by an accredited microbiology lab. This identifies the specific mold species present and its concentration, which is essential for understanding the health risk to your family and for planning an effective remediation strategy.

Given your children's symptoms and the villa's size, a DIY approach is not recommended. Hidden growth inside walls, a common issue in villas from minor leaks, requires professional detection tools. A proper inspection by a company with their own lab, like ours, provides the documented evidence needed to solve the problem at its source, not just mask the symptoms.
