Should You Try Chemical Cleaning For Your Aircon

Air conditioner maintenance is essential in extending the life of your aircon unit. Several practices contribute to keeping your unit in tip-top condition, allowing for efficient usage and lower utility bills. As you research on the various recommended practices, you may have come across the possibility of aircon chemical wash in Singapore.

Most homeowners are comfortable with simple wipe downs of their air conditioning unit and the compressor. However, they may be hesitant at the thought of using strong cleaning chemicals. Nonetheless, this is a crucial step in thoroughly clearing dirt and debris that have built up inside your system.

In this article, we give a brief overview of the steps that you can take to perform chemical washing.

Purchasing the Chemicals

To start, you will be needing a variety of acid or alkaline based cleaning chemicals, each are used for a different aircon unit component. These include:

  • An A/C condenser coil cleaner
  • An A/C evaporator coil cleaner
  • An ice machine cleaner
  • Lime and scale remover


Additionally, you may also wish to purchase a HVAC leak detector to help find any potential leaks in your air conditioner unit.

Method 1

The first method involves spraying the chemicals into the air conditioner unit without having first removed the fan coils. Relatively convenient, this method is preferred by homeowners as it is simple and quick. However, the chemical spray is often unable to reach all corners and components. As a result, the cleaning is not very thorough, risking the possibility of these other parts breaking down.

Additionally, it is difficult to completely rinse the unit, which means that chemicals may be left in the aircon unit, corroding it over time. It should be noted that any rinsing conducted should be done from the inside out so as to prevent chemicals from entering further into the unit.

Method 2

The second method of aircon chemical wash requires the dismantling of the fan coil. Also known as ‘Aircon Overhaul’, it is more complex and time consuming than the first method. For starters, you should bring the aircon unit to an open space before dismantling it. This serves to avoid releasing large amounts of dust and dirt into your home.

Each component of the air conditioner should be washed with your corresponding chemical cleaners before being rinsed thoroughly. Additionally, leak detectors can also be used before reassembling your unit. This process is more thorough and ensures that your air conditioner maintains its optimal efficiency.

The Value of Professional Chemical Cleaning

A complete chemical wash with the dismantling of the fan coil can take homeowners a significant amount of time and effort. Moreover, it does require some technical knowledge to reassemble and connect the aircon unit back to the system.

As such, it is strongly recommended that you engage a professional air conditioning service firm. In exchange for financial compensation, you would be rewarded with a peace of mind and additional services that will help to keep your air conditioner in peak condition.
