Thorough cleaning and reconditioning of the air-conditioner can help restore and improve its performance.

After several cycles of aircon servicing and chemical cleaning, a chemical overhaul can help increase your aircon system’s lifespan notably.
Occasionally, accumulating dirt particles that are uncleared for too long can be too stubborn and hard to remove. We employ an aircon chemical overhaul for situations like this where a regular aircon cleaning is not enough.

Why Do Aircon Units Need Chemical Overhaul?

A chemical overhaul is mainly recommended for air conditioners that have been continuously used but without maintenance. Under normal circumstances, those units will likely have a problem with water leakage, uneven airflow from the blower, or a mouldy or unpleasant smell when turned on.

In general, a chemical overhaul help to deal with the following issues:

  • Blockage of the vents due to accumulation of dust particles or other sediments
  • Severe damage to the evaporator coils
  • Fan bearings not working properly
  • Faulty or damaged air filters
  • Blockage of drainpipes causing water to overflow

The process aims to clean the air conditioning parts and machines that have not been cleaned for a long time. Therefore, the chemical overhaul process would require a keen and attentive eye for detail. It should not be confused with an aircon chemical wash.

What Is Included In Aircon Chemical Overhaul Servicing?

The aircon unit must first be dismantled from the wall and frame to ensure proper and thorough cleaning. Chemicals are then used to properly clean the air conditioner’s filters to ensure that the air expelled from the unit is clean and fresh.

This is important to prevent breathing problems and allergies associated with dirty air and dust particles accumulated in the conditioner.

The next step involves lubricating the fan bearings to ensure that the unit operates quietly without any noise.

If your air conditioner has a problem with water leakages, chemical cleaning is carried out on the drainage system to curb this problem and stop the leakage.
During a chemical overhaul, the fan evaporator coil is chemically washed to remove the accumulated dust and dirt so that heat is adequately transferred within the air conditioner.

All these chemicals used in a chemical overhaul of the air conditioner ensure that the unit gives you cool air that is clean by breaking down all the accumulated dust particles and dirt sucked by the machine from outside.


Air conditioning units, especially the older ones, often face small break down and issues that need quick troubleshooting to determine the root cause of the problem. Here at LK Brothers, our experienced experts will then be able to identify and solve the issue and repair your aircon unit.

Air Conditioner Inspection and Troubleshooting

Apart from chemical overhaul and aircon installation services, our professionals can help you with the following aircon troubleshooting services

Aircon Filter Trouble

Air filters in the air conditioning unit are responsible for purifying all the air that enters or leave the air conditioner.

As a result, it often develops a layer of dirt and impurities with each flow of air. This is very common for air conditioning unit, as usage increases. Usually, aircon servicing can help reduce this layer of dirt.

Beyond a certain point of usage, however, these filters expire and cannot be repaired or cleaned any further. In such situations, a change of air filter is required. At LK brothers, we carry spare filters for almost every known air conditioner brand.

Restore Thermostat Functionality

There is a small function of the air conditioner which allows you to set the room temperature you require for your room/surroundings. This is known as the thermostat.

It has a sensor that detects the present room temperature and regulates the air conditioner to reach and maintain optimal airflow. If the sensor is damaged, the temperature regulation will be affected. Your aircon might not dispense cool air, or it might cool the room too much.

Troubleshooting can help us identify if the thermostat is faulty.

If the fault lies with the thermostat, we can reset, reprogram or reset it according to the situation.

Clean the Thermal Coils

There are two heat exchanging spots in any air conditioning system, the condenser, and the evaporator. Each of these spots has a series of coiled shaped pipes which increase the flow time and supplement the energy exchange.

A thick layer of bacteria or dirt on these tubes can have affected your cooling system’s efficiency. The condenser and evaporator coils may have a fluctuating temperatures, which could result in complete system failure.

If so, you would require a cleaning liquid to remove the impurities within your machine. With our innovative aircon troubleshooting methods, we assure you that you will not face the same problem any time soon.

Remove Clogging

Whether you talk of the drainage system, capillary tubes or filters, every part of the air conditioner is prone to clogging. Each of these aircon parts has a different effect on the overall working of the cooling system.

For instance, blockage in the drainage system leads to water collection and potentially aircon leakage, whereas a clogging in the filter results in decreased airflow of the system. Clogging can also result in your aircon emitting a foul smell.

We can solve this problem by vacuuming or cleaning the affected areas, finding the culprit and eliminating it. We also have some powerful pumps to dissolve the impurities in tubes and other unreachable parts.

Fix Aircon Refrigerant Issues

The refrigerant is one of the most crucial and dangerous parts of the cooling system. This anti-freeze liquid is the part which transfers the heat from one unit to the other. Without this liquid, the system will stop working.

The refrigerant is colourless, odourless and pressurised, which makes it difficult to find the leak.

However, LKBrothers professionals have years of industrial experience and can deal with the problem very efficiently. We have many different types of tools to confirm the leakage, including the leak in air vents and fix the system if necessary.

Apart from the common aircon troubleshoot, we are here for replacement of defective aircon parts too – effectively aircon repairs.
