What Is an Aircon Chemical Overhaul and Why Is It Needed?
An aircon chemical overhaul is a deep cleaning and restoration process designed to bring your air conditioning system back to optimal performance. Unlike general servicing, this involves complete dismantling of the unit, chemical cleaning of the evaporator coil, fan blower, drain pan, and all internal parts to remove dirt, mould, and stubborn residue.
- Ideal when your aircon is not cold or airflow is weak even after normal servicing.
- Removes thick dust, algae, and bacteria that accumulate deep inside the system.
- Restores cooling power, improves air quality, and reduces energy consumption.
- Extends lifespan of compressors and evaporator coils.
- Recommended every 12–18 months for heavily used air conditioners in Singapore.

What Is the Difference Between Chemical Wash and Chemical Overhaul?
Both aircon chemical wash and chemical overhaul involve chemical cleaning, but they differ in depth and purpose.
-
Chemical wash is a partial cleaning where the unit remains mounted on the wall. It’s suitable for mild dirt and routine cleaning.
-
Chemical overhaul involves full dismantling of the aircon to clean every internal component thoroughly — ideal when performance is significantly reduced.
- If your aircon is not cold, leaking, or has odour after normal servicing, an overhaul provides the most complete restoration.
