What is Aircon chemical cleaning?

AC Chemical Wash

If you use your aircon regularly, then its performance might deteriorate over time. And the reason is simple – accumulation of dirt and dust. These substances gather in the filters and other components of the air conditioner, which not only influence its performance but also affect the life cycle.

Therefore, you must maintain your aircon properly. If you choose to ignore the problem, you might have to invest in repairs and even change the unit entirely. So it is always best to take precautionary measures. And one way to do so is chemical cleaning and washing. Let’s learn about these methods in detail.

What are steps followed in aircon chemical cleaning?

Aircon chemical cleaning involves taking each part of the aircon out of the unit and checking for the problems. Once the issues are diagnosed and fixed, the parts are cleaned thoroughly with chemicals. Firstly, the fan coil is removed from the wall and cleaned with the help of an appropriate chemical. Once it is cleaned, it is rinsed with cold water.

In this way, the coil can be protected from corrosion, which might occur because of the chemical. After the coil is cleaned, the fan bearings are greased. Then, internal air filters are chemically cleaned while the drainage pipes are passed through a chemical flush. Eventually, all of the components are fixed into the unit, ensuring that the aircon is running proficiently.

Here are some crucial steps involved in the aircon chemical wash:

  • Washing air filters, condenser coils, evaporator coils, blowers, and other parts using the appropriate chemical
  • Dismantling and evaluating the performance of the fan coil unit
  • Ensuring that all the significant electrical connections are appropriate with no loose wires
  • Checking the operations of critical parts of the aircon like the discharge pressure, the motor of the blower fan, and the compressor suction
  • Cleaning the front covers, as well as the panels, of the aircon.

Benefits of Aircon Chemical Wash


There are numerous benefits of getting an aircon chemical wash. Below we have highlighted some of the most important ones:

  1. Cleaning the dirt and dust from the aircon
  2. Filters easily get blocked with dirt and dust, causing unsanitary air to be circulated from the system to your surrounding. On the other hand, clogged filters can also prevent the free flow of air, which might put your system to work under enormous pressure. Eventually, your aircon will not only perform poorly, but it will also result in system break downs and return energy bills. In this way, aircon chemical wash can remove the dust and dirt from the unit, improve the quality of the air, and ensure your system works efficiently.

  3. Removing blockages
  4. The condenser in the aircon is responsible for facilitating heat exchange within the system. With this exchange, the air can be efficiently cooled. However, if the condenser is not cleaned efficiently, the blockages can make it challenging to maintain cold airflow. Fortunately, chemical cleaning makes it possible to remove all the internal, as well as external, blockages affecting the performance of the condenser. By cleaning the condenser, you can also prevent freezing in the aircon, which usually occurs when the air filter is dirty, the fan is not working correctly, or there are blockages in the air ducts.

  5. Maintaining the evaporator of the system
  6. The evaporator coils present in the aircon are very critical to ensure that the system is running efficiently. These coils can be cleaned easily using chemical washing, making sure that the dust and dirt buildup is removed. In this way, the coils can be avoidedby malfunctioning or breaking down.

  7. Identifying issues in the aircon components
  8. From the exterior, it may seem that the aircon is working correctly. However, a closer inspection helps in identifying critical issues much more appropriately. In this way, washing the system regularly can diagnose problems in the unit and ensure they get resolved. Some issues like leaking refrigerant need to be identified quickly, as they can be very harmful, especially for health. The technician can also ensure that other parts of the aircon such as the blower wheel and thermostat are working correctly.

Importance of Aircon Chemical Overhaul

Singapore is known for its warm climate. The conditions in the country eventually provoke the residents to rely on aircons, be it in their homes, offices, or cars. However, with the prolonged usage of aircon, many problems can arise in the system, such as noise and water leakage. These problems are mostly resolved with the help of chemical cleaning.

Here are some reasons for choosing an aircon chemical overhaul and wash.

  1. Preventing corrosion
  2. Extensive use of an aircon can make it challenging to reduce the damage caused by corrosion. Luckily, chemical overhaul can be beneficial in lowering fan oil corrosion and all the other related problems.

  3. Improving the appearance of the aircon
  4. By inspecting and cleaning the components of the aircon, you can get rid of all sorts of dust and dirt from the aircon. After all, why buy another unit when chemical wash can make your aircon look like just a new one?

  5. Protecting the aircon from further damages
  6. Just like any other technology, aircons might stop working in the long run. However, you can effectively improve the lifespan of your system with the help of a chemical wash. Problems like water leakage and blockage in the drainage systems can also be prevented at early stages.

Requirements of aircon chemical wash


Here are some indications when you might want to opt for aircon chemical cleaning:

  1. Leaking
  2. Your aircon might be leaking water in every run. This usually happens when there is backflow, and the drainage pipe has clogged up. In this case, chemical cleaning is a necessity.

  3. No cold air
  4. When ice accumulates in the condenser, the aircon is unable to generate enough cold air. If the fan coil is also dirty, then the aircon will produce warm air more than the cold one. In this regard, chemical cleaning can help restore the functioning of the aircon.

  5. Bad smell

With the accumulation of bacteria in the fan coil, the foul smell might be produced. This can be prevented with chemical cleaning as well.

How to choose a company for aircon servicing?

When opting for aircon servicing, it is necessary that you choose a suitable company. After all, there are many companies offering aircon services in Singapore. However, how can you trust a company, especially if you never availed these services? You should start by evaluating the brand image of the company.

Suppose you find positive reviews about the company online. Thus, it is likely that you will also have a good experience with the company. It is also crucial to see how accommodating the company is, which you see by reviewing the terms and conditions of its services, together with the customer service.

Most importantly, you should focus on your budget. A company might be perfect in every aspect, but can you afford its services? These considerations will help you in choosing the right company for aircon servicing.

Comparison b/w Aircon Chemical Wash & Aircon Chemical Overhaul

While aircon chemical wash and aircon chemical overhaul are both critical for your unit, there are considerable differences between both. A chemical wash basically involves removal of the dirt and dust from the aircon with the help of spray cleaning. This method is usually suitable if you want to increase the lifecycle of your system.

On the other hand, AC Service involving chemical overhaul is a more detailed assessment of the unit. It involves the technicians checking if the aircon’s parts are working. It also includes chemical washing of air filters, blowers, and coils, together with the removal of dirt and dust. In this regard, as the aircon becomes older, it is recommended to go for chemical overhaul, so it can continue to work optimally.

The minimum cost of aircon cleaning

Aircon cleaning services involving simple repairs usually cost anywhere from $75 to $590. However, suppose you want to get components like the drain pans, refrigerant, and fan motor fixed. In that case, the service can cost anywhere $240 or more. In this way, the price of the aircon cleaning definitely depends upon the condition of the unit and how much work is needed to fix it.

The number of aircon units being fixed also determine the total cost. In some instances, rates are determined by the hourly service provided over a week, for example, if you sign a contract for regular servicing with a company.

Is chemical cleaning part of aircon servicing?


Regular aircon servicing does not include chemical cleaning. Instead, it involves unclogging of the unit’s parts. On the other hand, advanced aircon servicing is far more complex, involving cleaning of parts like pressure gauges and the drainage system.

In The End

So do you have an aircon that is not working correctly? Do you feel it needs to be checked? Then, go ahead with chemical washing, which will improve the conditions of your aircon and also extend its life cycle.
