AC leak causing mold and cough: DIY or call professional?« Back to Previous Page

An AC leak causing visible mold and a persistent cough requires immediate professional attention, not a DIY approach. The UAE's high humidity and constant AC use create ideal conditions for mold growth, and what you see on the wall is often just the tip of the iceberg, with more growing inside the wall cavity or under the carpet from the sustained moisture.

Using bleach is ineffective on porous surfaces like drywall and carpet; it only bleaches the surface color and does not kill the root structure. More importantly, scrubbing can aerosolize spores, potentially worsening your husband's respiratory symptoms.

Given the health symptom—a persistent cough—the situation has moved beyond simple cleaning. A professional inspection is critical to assess the full extent of the water damage and mold growth. They will use moisture meters and borescopes to see inside the walls. The remediation process should include containing the area, removing the contaminated porous materials like the affected drywall and carpet padding, HEPA vacuuming, and using specialized antimicrobial agents.

For verification, insist on before-and-after testing. A reputable company should provide air or surface sample lab results to confirm the spore count has been returned to safe levels, which is the only way to know the environment is truly healthy again. This scientific validation is essential for peace of mind, especially with existing health concerns.
