The “best” way isn’t just cleaning the vents you can see; it’s a comprehensive process. First, you need a certified mold inspection (like we provide) to assess the entire system—the evaporator coils, drip pan, and ductwork, which are the real culprits. We use borescopes and air/o-surface sampling to identify the spore types and concentration levels.

The actual remediation involves isolating the HVAC system, using HEPA vacuuming on all ducts, and then applying an EPA-approved, non-toxic antimicrobial coating specifically designed for HVAC systems to the coils and interior surfaces to prevent regrowth. Simply wiping the vent grill is completely ineffective and can aerosolize spores, making the problem worse.

Given your son’s health, a DIY approach is strongly discouraged. UAE regulations, particularly from Dubai Municipality, have specific guidelines for indoor air quality and remediation practices that professionals must follow. We can provide a full assessment and a certificate of decontamination once the job is done, which is often needed for property management.

For a situation like this, please get a professional evaluation immediately. You can call our team at 800-MOLDS (800-66537) or email hello@saniservice.com to schedule an inspection.
