How to kill and prevent mold under AC in Dubai?« Back to Previous Page

The mold growth you've discovered under your AC unit is a serious concern, particularly in Dubai's climate. The constant high humidity, combined with condensation from a leaking AC, creates the perfect environment for mold to thrive on concrete and within the carpet backing. This is a common issue in villas across Jumeirah and the wider UAE.

The most effective method requires a multi-step professional approach. First, the AC leak must be identified and repaired by a certified HVAC technician to eliminate the moisture source. The affected carpet and underlay must be carefully removed and disposed of as hazardous waste to prevent cross-contamination. The concrete subfloor then requires specialized abrasive remediation (e.g., sandblasting or soda blasting) to physically remove the deeply ingrained mold, followed by application of an EPA-approved, non-toxic antimicrobial solution to kill residual spores. Finally, a mold-resistant sealant should be applied to the concrete before new flooring is installed.

For a case of this severity, a professional inspection is not just recommended but essential. DIY cleaning with bleach or vinegar is ineffective on porous concrete, can exacerbate spore dispersal, and fails to address the root cause. UAE regulations, particularly from Dubai Municipality, have strict guidelines for mold remediation to ensure occupant safety and proper disposal. Our certified technicians at Saniservice use advanced moisture meters and thermal imaging to identify the full extent of the contamination and execute a full containment and remediation protocol compliant with all local standards.

To prevent recurrence, ensure regular HVAC maintenance to prevent condensation leaks and consider using a dehumidifier. For a definitive solution to this health hazard, please contact our experts for an immediate assessment. Call 800-MOLDS (800-66537) or email hello@saniservice.com.
