9K – 15K BTU
Aircon Chemical Overhaul in Singapore is a comprehensive air conditioning maintenance method that involves the complete disassembly and intensive chemical cleaning of the aircon system. This process is designed to address and resolve issues such as water leakage and prevent potential system failures, ensuring the delivery of clean and healthy air.
The procedure includes lubricating fan bearings to guarantee silent operation, free from any noise disturbances. It also involves a thorough inspection of the unit’s thermostats and controls. The overhaul process uses specialized chemicals to meticulously clean components like pipes, blower wheels, and drain pans. Additionally, the fan evaporator coil is cleaned to ensure efficient heat transfer and prevent the accumulation of dust and grime. Any faulty bearings are replaced to eliminate operational noise.
This type of overhaul is particularly beneficial for air conditioning systems that have been in use for an extended period or have not received regular maintenance. It helps in restoring the aircon to its peak performance and prolongs its lifespan. During the chemical overhaul, a skilled technician will disassemble the air conditioner and employ specific chemicals to clean and treat various parts, including the evaporator and condenser coils, as well as the drainage system.

Our Aircon Chemical Overhaul Process

Dismantle whole aircon unit
The key distinction in an aircon chemical overhaul is the full disassembly of the unit by the technician. Every component is meticulously taken apart and treated with a specialized chemical solution to eradicate accumulated dust. This process ensures that all dirt is effectively removed and sanitized, leading to improved air quality and cooler air output.
Lubricates fan bearings
Post-treatment, components often lose their lubrication, necessitating reapplication of oil. This step is crucial, especially for fan bearings, to enhance their efficiency. Proper lubrication not only speeds up the fans but also significantly reduces operational noise.


Reinstallation and Testing
Once the overhaul is complete, the technician reassembles all parts. This precise reinstallation is why professional expertise is essential. The technician then conducts a thorough test to check electrical connections, ensuring safety, correct circuit functioning, and verifying there are no water leaks and that the aircon operates effectively.
Checking Refrigerant Level
The final step involves checking the air conditioner’s refrigerant level, a critical factor for its energy efficiency and performance. Technicians use a gas gauge for this assessment and, if necessary, top up the refrigerant gas. This ensures the aircon provides the coolest and freshest indoor environment.

Signs You Need an Aircon Chemical Cleaning in Singapore
An aircon chemical cleaning in Singapore involves thoroughly washing the internal components of your unit with chemical solutions to eliminate built-up dirt, mould, and bacteria—restoring cooling efficiency and improving air quality.
Poor Cooling Performance
Air conditioners are designed for efficient cooling. If your unit takes too long to cool a room or fails to produce cold air, it could be due to ice accumulation in the condenser. In such cases, a detailed maintenance process is necessary to defrost the coils and check for any damages.
Water Leakage
Clogged coils can lead to water being trapped and overflowing in the unit, resulting in leaks or water spray. Since it’s challenging to determine if the coils are clogged, a complete aircon maintenance overhaul is often recommended.
Foul Odour
An unusual smell from your air conditioner is not normal and could indicate bacterial growth inside the unit. A thorough maintenance process can effectively eliminate these bacteria.
Noisy Unit
A loud air conditioner often suggests internal damage, such as clogged coils, water buildup, or loose bearings. A comprehensive maintenance overhaul, which involves disassembling the unit, can identify and resolve these issues. After the maintenance, a test run will determine if the noise issue has been resolved.
For those looking for a quicker and less invasive option, our chemical wash service offers a faster solution for purifying your system without the need to dismantle the entire unit.

Frequently Asked Questions
What is the difference between an aircon chemical wash and an aircon chemical overhaul?
An aircon chemical overhaul involves fully dismantling the unit to deep clean each internal component, including coils, blower wheels, and drainage systems. In contrast, a chemical wash is less invasive and does not require full disassembly. Overhauls are recommended for older units or when regular maintenance hasn’t resolved performance issues.
