Should I clean mold myself or call a pro for AC leak?« Back to Previous Page

A small patch from a recent AC leak can sometimes be handled yourself if you address the moisture source first. The leak must be repaired by your building maintenance or an AC technician; otherwise, the mold will return regardless of cleaning.

For a surface under 1 square meter, you can clean with a vinegar solution or a dedicated mold cleaner, not bleach. Bleach does not kill mold roots on porous surfaces and its fumes are hazardous in enclosed spaces. Always wear an N95 mask and gloves during cleaning.

However, professional remediation is strongly advised if the mold is inside the AC unit itself, the wall cavity, or if the area is larger. Dubai's high humidity allows hidden mold to spread quickly. A professional inspection, often involving moisture meters and borescopes, identifies the full extent of the contamination that isn't visible. They then contain the area to prevent spores from spreading during cleaning.

The cost for a professional job is tied to the scope of work, not just the visible spot. It covers containment, air filtration, safe removal of affected materials, and antimicrobial treatment. For a small, contained leak, the process is typically straightforward. For an accurate assessment and quote, you would need a company to diagnose the hidden moisture damage.
