Your Dirty Aircon Could Be Making Your Family Sick
An aircon unit that’s not regularly cleaned becomes a breeding ground for
bacteria, mould, and harmful biofilms inside the fan coil and water tray.
Every time it runs, it blows contaminated air directly into your living space —
triggering respiratory issues, allergies, and worsened asthma, especially in children and the elderly.
A professional chemical wash eliminates these hidden health hazards completely.
