Mold from AC leak: DIY or professional cost in Dubai?« Back to Previous Page

Black mold from an AC leak is a health concern and should be professionally assessed. In Dubai's climate, constant humidity and condensation from a leaking unit create an ideal environment for mold to thrive, often leading to the types you cannot see inside the wall cavity.

For a situation that has persisted for months with visible growth and associated health symptoms like congestion, a DIY approach is not recommended. Surface cleaning with bleach is ineffective on porous materials like drywall and can disturb spores, spreading them further. The critical step is identifying and repairing the moisture source—the AC leak—which requires a certified HVAC technician.

Professional remediation involves containment to prevent cross-contamination, safe removal of affected building materials, and HEPA vacuuming to capture spores. The final cost is determined by the extent of the hidden damage. It hinges on the square footage of contamination, how deep it has penetrated the wall, and if the AC unit itself is contaminated. You will need a detailed inspection to get an accurate scope and quotation.

For a verified outcome, ensure the company provides before-and-after lab reports to confirm the species and that spore counts have returned to normal indoor levels. This is the only way to confirm the problem is resolved and your indoor air is safe.
