The Complete Guide to Aircon Chemical Overhauls

An aircon chemical overhaul is an essential procedure that ensures the optimal performance of your air conditioning unit. In this comprehensive guide, we dive into the specifics of this procedure, its advantages, and why it may be a critical choice for your air conditioning system.

Understanding the Aircon Chemical Overhaul Process

An aircon chemical overhaul is a systematic procedure to restore your air conditioning system to optimal performance. This process involves meticulously examining all components and employing high-quality chemical solutions to clean each part of your aircon unit thoroughly.

This deep-cleaning process removes accumulated dust and debris in the fan evaporator coil, leading to enhanced heat dissipation and improved performance. It’s a preventive measure that can extend your aircon’s lifespan by rectifying potential faults early.

Distinguishing between Aircon Chemical Overhaul and Chemical Washing

Though both methods involve chemical solutions, aircon chemical overhaul, and chemical washing differ significantly in the scope of work and situations in which they are applied.

Aircon Chemical Overhaul

An aircon chemical overhaul is an in-depth cleaning, maintenance, and potential repair procedure typically carried out when a problem is detected with the aircon unit. This procedure includes disassembling the entire aircon system to meticulously inspect, repair, or replace damaged parts, thorough chemical cleaning, and fixing any water leakages.

The fan bearings are lubricated for smooth, noiseless operation, the fan evaporator coil is chemically cleaned for better efficiency, and blocked vents are cleared to ensure the cleanliness of the circulated air.

Aircon Chemical Wash

Chemical washing, on the other hand, is a less intensive process typically performed more frequently as preventive maintenance. It doesn’t involve disassembling the aircon unit. Instead, it focuses on cleaning the aircon using chemical reagents without part replacement.

Comparing Costs and Benefits: Normal Servicing, Chemical Cleaning, and Chemical Overhaul

While regular servicing and chemical cleaning are preventive measures to maintain your aircon’s performance, a chemical overhaul is necessary when performance issues arise.

Regular servicing is less expensive than chemical overhaul and chemical wash, but it only involves cleaning the filter, drainage system, temperature, pressure gauges, condenser, and pipes. It doesn’t utilize chemical solutions; the cleaning is done without removing the units from the wall.

Even more expensive than regular servicing, chemical washing is cheaper than a chemical overhaul. It involves a thorough cleaning with chemical solutions but without disassembling the unit.

A chemical overhaul, the most complete procedure, is the priciest option. It includes the cost of potential repair and replacement of parts and the extensive cleaning process.

Though each service comes at its own cost, investing in these maintenance procedures can be economically sound in the long run compared to replacing an entirely broken aircon due to a lack of proper maintenance.

Weighing the Pros and Cons of Chemical Overhauling

Like any other procedure, a chemical overhaul has advantages and disadvantages.


  1. An aircon chemical overhaul ensures thorough cleaning of your aircon unit, resulting in enhanced air quality.
  2. It involves a deep inspection and potential repair or replacement of malfunctioning parts, hence improving the efficiency and lifespan of your aircon.
  3. It helps prevent future issues by rectifying problems in the early stages.


  1. The process of a chemical overhaul can be time-consuming due to the extent of the inspection and cleaning involved.
  2. It is generally more expensive than other aircon servicing options.

Advantages of Chemical Cleaning Your Air Conditioner

Air conditioning units, like any other machine, require regular maintenance to function optimally. One such crucial maintenance practice is chemical cleaning. This article will explore the inherent benefits of aircon chemical cleaning and provide a detailed understanding of the telltale signs that signify your aircon unit needs a chemical cleaning.

Advantages of Chemical Cleaning

Air Conditioner Chemical Cleaning: An Overview

A chemical cleaning procedure involves an experienced technician disassembling your air conditioning unit from its mounting point. They then meticulously clean critical parts of the system, such as air filters, fan evaporator coil, and other integral components, using a specially formulated chemical solution.

The same treatment is applied to the drainage system if your aircon unit suffers from water leakage issues. The procedure concludes with the lubrication of fan bearings to diminish noise levels.

Decoding the Signs: When Does Your Air Conditioner Require a Chemical Cleaning?

Knowing when to conduct an aircon chemical cleaning can save you from unexpected breakdowns and hefty replacement costs. Here are some prevalent symptoms that your air conditioner may need a chemical overhaul:

  • Cooling takes longer than usual.
  • Noticeable increase in noise levels when the unit is turned on.
  • A foul odor is emanating from the unit.

The Multifaceted Benefits of Chemical Cleaning Your Air Conditioner

Elevating Air Quality

Over time, your air conditioner can become a repository for dirt, dust, and other particulate matter that can adversely affect the air quality in your room. These particles can harm individuals suffering from respiratory conditions like asthma or allergies.

Undertaking an aircon chemical cleaning rids your unit of these pollutants. The process thoroughly cleans the air filters and other components, circulating healthy air around your premises.

Enhancing the Lifespan of Your Unit

Just as regular servicing can extend your car’s life, the same principle applies to your air conditioner. A chemical wash ensures thorough cleaning and allows the technician to inspect individual parts and advise on any necessary replacements or repairs. The result is an air conditioner that operates as efficiently as when it was brand new.

Increasing Energy Efficiency

An air conditioner laden with dirt and debris will have to work doubly hard to circulate air, leading to elevated energy consumption and a surge in your electricity bill. By conducting a chemical cleaning, you eliminate this build-up and restore your aircon unit to its original efficiency, leading to substantial energy savings.

Preventing Component Freezing

Certain parts of your air conditioner, particularly those dealing with refrigerants and cooling elements, are susceptible to freezing if not appropriately maintained. A chemical cleaning ensures that your aircon’s coils and pipes remain clear, preventing potential freezing and subsequent breakdowns.

Eliminating Foul Odors

Mold and mildew build-up in your air conditioner can lead to unpleasant odors. Detecting a foul smell from your unit clearly indicates that your air conditioner needs a chemical cleaning. Not only does this process eliminate the odor, but it also prevents future bacterial build-up.

Eliminating Foul Odors


When opting for aircon maintenance services, ensure that the service provider does more than just chemical cleaning. A comprehensive service should include essential maintenance, checks for component repairs or replacements, and problem troubleshooting.
