Keep reading this blog post to find out more!

What Is An Aircon Chemical Overhaul?

An aircon chemical overhaul refers to an extensive cleaning and maintenance procedure for air-conditioning systems. It involves the use of specialized chemicals to remove dirt, dust and mould build-up on the evaporator coils and other interior components.

The chemicals also help in ridding the system of bacteria, allergens and fungi that can lead to poor indoor air quality. Ultimately, it can help restore a unit’s original cooling capacity while reducing energy consumption.

The process is often recommended when an AC has been underperforming or not functioning at all due to damage or improper maintenance.

Pros Of An Aircon Chemical Overhaul

An aircon chemical overhaul offers many benefits, from improved cooling performance to reduced energy costs. Discover more in this blog post!

Cleaner Air Quality

Maintaining a clean and healthy atmosphere in your home or office is important, and an aircon chemical overhaul can help achieve this. Through the use of specialised chemicals, pollutants such as moulds and dust particles that accumulate on airconditioner components are eliminated. This not only provides cleaner air to breathe but can also minimise any potential health hazard that those pollutants may pose.

The improved airflow from an overhauled unit also enhances efficiency by increasing cooling capacity and reducing energy costs over time. Specialised sealants within the system also reduce the possibility of gas leakage due to wear-and-tear which improves overall indoor air quality compared to unserviced units.

Reduced Energy Costs

A great advantage of aircon chemical overhaul is the potential to reduce energy costs. By regularly maintaining your air conditioner, it can become more efficient and use less electricity when running, meaning lower utility bills each month. Furthermore, using modern chemicals can help reinforce components which would otherwise need replacing due to wear and tear over time thus reducing energy consumption.

Moreover, the improved cooling performance that comes with regular maintenance can make the AC operate efficiently in a shorter period of time for maximum output rather than leaving it working for long hours at its maximum capacity. This helps save energy by making sure that only the required amount is used for desired temperatures during operation.

Enhanced Cooling Performance

An aircon chemical overhaul may drastically improve the cooling performance of your unit. This is done by cleaning the evaporator coil, which gives it extra efficiency during hot summer days and boosts its capacity to cool down your home.

Additionally, a professional will inspect other components of your HVAC system like filters and ducts, making sure they are all in perfect condition. This helps ensure that the maximum possible heat exchange takes place within the air conditioning cycle resulting in peak cooling performance.

Prolonged Lifespan

One of the biggest advantages of an aircon chemical overhaul is that it can help to extend the lifespan of your unit. This type of maintenance prevents corrosion and rust, which are major causes of the breakdown of air conditioners. With regular servicing, problems such as clogged condenser coils and leaking refrigerant can be avoided.

Furthermore, an aircon chemical overhaul helps to reduce wear and tear on parts by removing dirt and debris from all components of the system using special chemicals. This reduces stress on these components making them last longer before they need replacement or repair due to age-related deterioration.

Lower Repair Costs

Aircon chemical overhauls reduce the need for future repairs, providing significant savings in the long run. The process eliminates internal sludge that builds up over time and stagnates airflow which can lead to higher electricity bills and compressor wear-and-tear resulting in costly repairs.

By performing a regular chemical overhaul, users can save hundreds of dollars on repair costs since most parts are kept functioning properly.

Cons Of An Aircon Chemical Overhaul

Although there are some advantages to aircon chemical overhauls, they also come with some drawbacks that users should consider. Read on to learn more about the cons of this service.


An aircon chemical overhaul can be an expensive process. Depending on the size of the system and its components, it may cost hundreds or even thousands of dollars to have a professional complete an overhaul properly. This can be especially true if any parts need to be replaced or serviced during the overhaul.

It is important to factor in the potential costs when deciding whether an aircon chemical overhaul will benefit you in the long run as it is a significant expense that requires careful consideration. If your system has been experiencing multiple repairs and malfunctions, then investing time and money into an upgrade may provide numerous benefits for years afterwards.

Hazardous Chemicals Used

The use of chemical agents in an aircon chemical overhaul often requires the usage of hazardous chemicals. These are generally refrigerant gases, which pose significant health risks if inhaled or handled improperly. Additionally, these chemicals also contribute to environmental pollution when released into the atmosphere.

To counter this problem, there are air conditioning systems that use non-toxic and environmentally friendly refilling chemicals such as R410A and Puron instead of harmful refrigerants commonly used in older units such as R22 Freon or HCFC-141b. While these new solutions may be more costly than traditional methods, they can help minimize the risk posed by hazardous substances while increasing efficiency and prolonging system lifespan.

Complex Process

An aircon chemical overhaul is a complex process that requires a high level of skill and expertise. It involves dismantling the entire system and components, cleaning, inspecting, cleaning filters, testing electrical connections and using specialized chemicals. These processes must be carried out with precision to ensure the efficient operation of the air conditioning unit.

Moreover, various other tasks such as cleaning the outer parts of the condenser fan motor, compressor check-up along with lubricating bearings are also undertaken during this time-consuming process. In addition, technicians also have to check for wear on contactors or relays which may need replacing before an effective refrigerant cycle can be established again in order to produce cold air from the system.

Maintenance Requirements

Regular maintenance is critical for an aircon chemical overhaul to prevent problems and ensure the system remains efficient. The user must inspect their system regularly, at least twice a year, and make sure all components are properly cleaned or replaced as needed.

Furthermore, all chemicals used during the process have specific expiration dates which should be adhered to in order to avoid spoilage. Additionally, regular servicing by a professional technician is essential as they can identify potential issues before they become serious and costly problems.

Risk Of Damage

The risk of damage is always present when performing any kind of maintenance on an aircon system. Chemical overhauls are particularly risky as they involve the use of chemicals and equipment that can potentially cause irreparable damage to certain parts.

It is important to only hire experienced professionals who will be able to recognise potential risks and will take steps to minimise them. It’s also important for users to familiarise themselves with what should not be done during a chemical overhaul in order to further reduce the chances of accidental damage.


An aircon chemical overhaul can provide numerous benefits including cleaner air quality, reduced energy costs, enhanced cooling performance, prolonged lifespan and lower repair costs. However, an overhaul also has some disadvantages such as costliness and the use of hazardous chemicals which may pose risks to humans and property.

Additionally, it is a complex process that requires professional expertise for safety reasons. Maintenance is essential for ensuring its success.

All in all, careful analysis of potential pros and cons should be made before opting for this service.
