The headaches are a significant health concern, as they are a common symptom of exposure to mycotoxins released by certain types of mold, including the notorious Stachybotrys chartarum (often referred to as “black mold”). This is not a simple cleaning task; it requires a certified mold inspection to identify the exact species and the full extent of the contamination, which often spreads deep within the ductwork and the AC unit itself.

Attempting to clean it without proper containment, HEPA filtration, and antimicrobial agents will likely aerosolize the spores, spreading the contamination throughout your villa and exacerbating health issues. A professional remediation for a villa AC system is typically a full-day process. It involves containment of the work area, HEPA vacuuming of all ducts, abrasive cleaning of coils and drain pans, and application of EPA-approved antimicrobial solutions to prevent regrowth.
