AC leak causing mold and dampness: urgent help needed?« Back to Previous Page

The situation you've described requires immediate attention. That combination of a persistent AC leak, visible black growth, and new respiratory symptoms in a bedroom is a clear sign of an active mold issue. The damp feeling confirms high humidity levels, which mold thrives on.

In Dubai's climate, AC units are a primary source of condensation and leaks are a frequent cause of indoor mold. The black speckled patches are likely a growth originating from the wet carpet and drywall, and without the proper equipment, it's impossible to identify the species or the extent of the growth inside the wall cavity or AC unit itself. Your husband's stuffy nose is a common reaction to mold spores in the air.

This is not a DIY project for the weekend. Cleaning visible spots with bleach only addresses the surface and will not stop the root cause: the moisture from the leak. The wall and carpet padding are likely saturated, acting as a reservoir for further growth. Disturbing it without containment can aerosolize a high concentration of spores throughout your home.

You need a two-step professional approach. First, an HVAC technician must repair the AC leak at its source. Second, a mold inspector should conduct an assessment, often involving moisture meters and possibly air or surface sampling, to determine the full scope of contamination and create a remediation plan. Proper remediation involves isolating the area, removing contaminated porous materials like drywall and carpet, and using specialized air scrubbers to clean the air.

For reputable providers, look for companies that conduct pre- and post-remediation testing to verify the environment has been returned to a healthy state, a standard practice for science-driven firms.
