Is AC leak causing dangerous mold under carpet?« Back to Previous Page

Yes, the mold growth under your carpet from an AC leak is a legitimate health concern that requires prompt attention. In Dubai's high humidity, even a small, persistent leak creates ideal conditions for mold colonies to establish themselves rapidly on organic materials like carpet backing and concrete.

You should notify your landlord immediately. While it may not constitute a "burst pipe" level of emergency, it is a situation that demands action within days, not weeks. The continuous moisture feed means the colony is actively growing and releasing spores into your bedroom's air. Common reactions include worsened allergies, asthma, coughing, and sinus congestion, particularly as you sleep there for hours each night.

For remediation, simply wiping the visible spots is insufficient. The mold's root system (hyphae) penetrates porous surfaces like concrete. Proper protocol involves isolating the area, removing the contaminated carpet section, and professionally HEPA-vacuuming and treating the subfloor to prevent regrowth. The AC unit itself must also be inspected to stop the leak at its source; this is often a clogged condensate drain line, a very common issue here due to dust and year-round operation.

Before any work is done, consider documenting the issue with photos for your landlord. For verification of a proper cleanup, the gold standard is a post-remediation viability test from an independent lab to confirm spore counts have returned to normal indoor levels.
