Mold behind AC in Dubai: professional cost and DIY?« Back to Previous Page

The mold behind your AC is likely caused by the continuous condensation from the leak, a very common issue in Dubai's humid climate where AC units run year-round. For a patch that size, professional remediation is strongly advised over DIY.

Bleach is not recommended; it only removes surface discoloration on porous materials like drywall and does not address the root cause or the hyphae growing within the wall. This can leave the problem to return. The process requires containment to prevent spores from spreading to other rooms, specialized antimicrobials, and safe removal of contaminated building materials.

The total cost for professional remediation is influenced by the extent of hidden damage. Technicians must open the wall to assess the full scope, which dictates the project's scale—from treating the immediate area to potentially replacing a section of insulation and drywall. For accurate pricing, you must get an on-site assessment and itemized quote from a certified provider.

Given your reported congestion, identifying the mold type is also important. Some species common in damp indoor environments can cause the symptoms you describe. A reputable company with its own microbiology lab can take a sample to determine the species and concentration, which informs the remediation protocol and confirms the environment is healthy after cleanup.
