In Singapore’s hot, humid climate, air conditioners work almost every day to keep homes and offices cool. Over time, dust, mold, bacteria, and greasy dirt build up inside the system—especially within the fan coil, filters, and drainage tray. This buildup not only reduces cooling efficiency but also causes bad odors, water leakage, and health issues such as allergies and respiratory problems. That’s why many homeowners frequently ask how much chemical wash costs and whether it is really necessary. A professional aircon chemical wash helps to deep-clean internal components, restore cooling performance, and extend the lifespan of your air conditioner.
