Should I hire a professional for black mold under my AC?« Back to Previous Page

Given the size of the patch and that it's hidden under carpet from a persistent AC leak, this requires a professional assessment. In Dubai's high humidity, what you see is often just the surface growth; the real concern is the moisture wicking into the wall cavity and underfloor, creating a much larger colony you can't see.

A DIY surface clean with bleach or vinegar will only address the visible mold on the carpet backing, not the root moisture problem or the hidden growth. Disturbing it without proper containment can also aerosolize spores, spreading them to other parts of your apartment.

Professional remediation is strongly advised here. A reputable company will first conduct an inspection, often using a moisture meter and borescope to assess the extent within the wall. The process involves isolating the area, removing the contaminated carpet section, drying the subfloor and wall structure with industrial equipment, and HEPA vacuuming to remove all spores. They should also diagnose and fix the AC leak source, as ongoing condensation is the primary cause.

Cost is variable and depends entirely on the extent of the damage behind the wall. For a contained leak like this, it often involves a few days of work for assessment, containment, drying, and verification. You should request an on-site assessment from a certified provider to get an accurate scope and quote. The investment is in ensuring the problem is solved completely to protect your indoor air quality and property.
