How to quickly test AC mold making family sick?« Back to Previous Page

Stop using that AC unit immediately and close off the spare room if possible. The combination of fuzzy black spots on clothes and a damp smell strongly suggests active mould growth, which is a common irritant causing persistent coughing, especially in children.

For the fastest way to get a definitive answer, you need professional air and surface sampling. In Dubai, your situation warrants a certified indoor environmental professional who can conduct immediate on-site testing. They will use equipment like air pumps to collect spore samples from the living areas and directly from the AC unit's ductwork. Given the older building construction in Deira and the year-round AC use creating condensation, the system is a prime suspect. The collected samples must be analyzed by an accredited microbiology lab to identify the specific mould types and concentrations.

Look for a provider that can dispatch an inspector quickly and offers expedited lab processing; some can turn around preliminary results within 24-48 hours. This is not a DIY situation—store-bought test kits are unreliable and will not give you the species identification or concentration data needed to understand the health risk. The inspection should also include a moisture survey to find the water source, as simply cleaning the visible mould without fixing the underlying humidity issue will lead to rapid regrowth. Once you have the lab report, you will know exactly what you're dealing with and can proceed with targeted remediation.
