Aircon Chemical Overhaul Process: A Step-by-Step Guide

Like any other electrical appliance, air conditioners need maintenance in order to work perfectly. One of the services we provide for aircon cleaning is chemical overhaul. It is deep cleaning of air conditioner components to remove dirt, mold, and grime build-up. Let’s know how aircon technicians perform chemical overhaul in this step by step guide. 

 

What is an Aircon Chemical Overhaul?

Chemical cleaning of an air conditioning unit is often referred to as a chemical overhaul. It is a more thorough cleaning process than ordinary servicing. This method involves cleaning all physical parts of the air conditioning unit with appropriate chemicals for better performance and longevity.

 

Reason for Aircon Chemical Overhaul

Because of continuous use, the inner components of the air conditioning unit accumulate dirt, dust, or even mold. This hinders its ability to cool properly, increases energy consumption, decreases efficiency and life span. Ordinary steam cleaning of the unit might not be adequate to unclog all the components. Hence, chemical overhaul improves air quality and cooling effectiveness of the system.

 

When is Aircon Chemical Overhaul Done?

If you encounter the following issues you might likely need an aircon chemical overhaul:

• The set temperature is not reached by the air conditioner.
• Your air conditioner unit has a strange smell.
• The air conditioner unit makes strange noises.
• If the air conditioner unit starts leaking water.
• The air conditioner has not undergone maintenance for quite some time. 

 

Aircon Chemical Overhaul Procedure – Step by Step

Below are few steps that experienced technicians follow for a perfect aircon overhaul: 

Step 1: Cut off the Power Supply

Safety always comes first. In the first steps of the procedure, the technician turns off the air conditioning unit and unplugs it from the electric socket. This avoids electric shocks while doing an overhaul. 

Step 2: Disassembling of the Air Conditioner

After the power is off, the AC unit is disassembled by the technician in a gentle manner. The cover, air filters, fan coil unit and the drain pipe are removed. Every part is removed so that it is possible to clean all the components thoroughly. 

Step 3: Chemical Cleaning of the Fan Coil Unit 

Fan coil unit is one very dirty component of the unit which tends to have a lot of dirt and mold build up. Cleaning the coil is done by the technician with a special chemical solution.It is essential to rinse the coil off with water after this procedure so that all traces of the chemical are washed off.

Step 4: Cleaning the Air Filters

One of the most neglected components of an air conditioner is its air filters. Dust and other microscopic particles will clog air filters, making breathing difficult. The technician will clean all trapped dirt with the same chemical solution.

Step 5: Flushing the Drainage System

Debris or mold can block the air conditioner’s drainage pipe that can lead to water leakage. The technician cleans out the drainage system with chemicals, which helps to get rid of clogs. It will ensure proper water drainage which means no future leaks will be experienced.

Step 6: Chemical Treatment for the Blower Wheel

The blower wheel’s role is to push air around the room, and this causes them to become dirty. A technician will clean the blower wheel thoroughly using the chemical solution. After using the chemical, he will remove all chemicals by rinsing with water.

Step 7: Chemical Cleaning of the Condenser Coil  

The aircon system contains condenser coils which are responsible for the heat exchange. The technician scrubs the condenser coil using chemicals to eliminate the dirt and filth. After applying the chemicals, the coil is washed properly with water to remove all residues. 

Step 8: Inspecting and Cleaning the Fan Motor  

The fan motor suffers from wear and tear like any other aircon components and so it needs checking periodically. During chemical overhaul, the technician lightly scrubs the motor’s surface if required. If required, he will replace the fan motor for the malfunctioning unit.

Step 9: Lubrication of Moving Parts  

The fan along with the motor moves in the aircon system. This set of components requires lubrication. After cleaning the parts, the technician will lubricate all of them. Lubrication minimizes friction which reduces sound and also improves the overall functioning of the system.  

Step 10: Reassembling the Air Conditioner  

After cleaning the air conditioner, the coil, and the other parts of the system, the technician puts them together. Each component should not be misplaced. Once everything is in order, the unit will function properly.

Step 11: Final Testing

The technician plugs in the air conditioning unit after it has been reassembled. They check to see if it operates properly. This final evaluation involves checking cooling, noise, and airflow. If there are no problems, the chemical overhaul is considered complete. 

Conclusion

An aircon chemical overhaul is an essential cleaning activity for keeping your air conditioner in top shape. It ensures that all components of the air conditioner are cleaned properly so it can cool better and the equipment lasts longer. If you are experiencing poor cooling, abnormal sounds, or leakage, these are signs your unit may need a chemical overhaul.
