Aircon service
An air conditioner (AC) chemical wash is a deep cleaning process that helps restore the efficiency of an air conditioner by removing dirt, mold, bacteria, and other pollutants from its internal components. Unlike a standard AC service or cleaning, a chemical wash involves using specialized cleaning solutions that break down and remove stubborn contaminants, ensuring the system operates at peak efficiency. One common question that arises regarding this process is: how long does an aircon chemical wash take?
The answer depends on several factors, including the type of air conditioner, the extent of the buildup inside, the complexity of the system, and the experience of the technicians performing the service. In this article, we will explore the factors that influence the duration of an aircon chemical wash, the step-by-step process involved, and how long each stage typically takes.
What is an Aircon Chemical Wash?
Before delving into the timeline of the process, it's important to understand what an aircon chemical wash entails. An air conditioner works by circulating air through its evaporator coils, filters, and fans. Over time, dust, dirt, and mold can accumulate in these components, affecting the unit's efficiency. In some cases, the pollutants can even cause unpleasant odors or health issues.
A chemical wash is a more thorough and intensive cleaning method than standard cleaning. During this process, a chemical cleaning solution is used to break down grease, dust, mold, and other contaminants that have accumulated within the system. The wash is applied to the unit's internal components like the coils, drain pan, and filters to remove stubborn buildup that regular cleaning may not be able to address. After the solution is applied, the components are rinsed and cleaned with high-pressure water or other methods to ensure the system is thoroughly cleaned.
Factors Affecting the Duration of an Aircon Chemical Wash
Several factors influence how long an aircon chemical wash takes. These include:
- Type of Air Conditioner: The type of air conditioner can significantly impact the duration of the chemical wash. A standard wall-mounted split air conditioner, for instance, will generally take less time to clean than a central air conditioning system or larger commercial units, which have more complex systems and multiple components to clean.
- Size of the Unit: Larger units or those with multiple parts (such as commercial air conditioning systems) will typically require more time for the chemical wash. A small residential unit may take less than an hour, while larger, more complicated systems can take several hours.
- Level of Contamination: The more contaminated the air conditioner is, the longer the wash will take. If there is extensive buildup of dirt, mold, or bacteria, the technician may need to spend more time applying the chemical solution, scrubbing, and rinsing the components.
- Technician Experience: An experienced technician may be able to complete the chemical wash more quickly because they are familiar with the process and know the most efficient methods for cleaning. In contrast, less experienced technicians may take longer to ensure the job is done thoroughly.
- Access and Location of the Unit: If the air conditioner is difficult to access or located in a challenging position (for instance, in a high-ceilinged room or a hard-to-reach corner), it may take longer to complete the wash. Technicians may need extra time to carefully dismantle parts or reach specific areas.
- Condition of the Filters: Filters play a major role in maintaining the efficiency of the air conditioner. If the filters are heavily clogged, they may need more time to clean or may even require replacement, which can increase the total time for the chemical wash.
- Rinsing and Drying Time: After applying the chemical solution, the components of the air conditioner need to be thoroughly rinsed to remove any residue. The drying time for each part will vary, and this process can add extra time to the service, especially if the system has multiple components that require drying.

Step-by-Step Process of an Aircon Chemical Wash and Duration
A typical aircon chemical wash process involves several steps, each with its associated time. Here's a breakdown of the stages:
- Preparation and Inspection (10-15 minutes): Before starting the chemical wash, the technician will inspect the air conditioner to assess its condition. This step includes checking the filters, coils, and other components to determine the extent of contamination. During this time, the technician may also prepare the area by setting up the necessary tools and equipment.
- Disassembling the Air Conditioner (15-30 minutes): Depending on the model of the air conditioner, some parts may need to be removed or disassembled to access the internal components. This step includes removing the front panel, filters, and other parts that are necessary for cleaning. The technician may also need to disconnect the power supply to the unit for safety. For larger or more complex units, this process may take longer.
- Applying the Chemical Solution (15-30 minutes): The chemical cleaning solution is sprayed onto the evaporator coils, filters, and other affected areas. The solution works to break down grime, mold, and other contaminants. The technician may need to let the solution sit for a short period to fully break down the buildup. This stage typically lasts between 15 and 30 minutes, depending on the size and contamination of the unit.
- Scrubbing and Cleaning (20-40 minutes): Once the chemical solution has had time to work, the technician will scrub the coils, fins, and other areas that need extra attention. A soft brush or other tools may be used to ensure that the contaminants are completely removed. For large or heavily contaminated units, this process may take longer.
- Rinsing and Flushing (20-40 minutes): After the scrubbing is complete, the technician will flush the system with water or use a high-pressure hose to remove the chemical solution and any remaining dirt. This stage is essential to ensure that no chemical residue remains in the system, as this could affect air quality and system performance.
- Reassembling the Unit (10-15 minutes): Once the system has been thoroughly cleaned and rinsed, the technician will reassemble the air conditioner, reinstalling the filters, panels, and any other components that were removed during the process. This step may take 10-15 minutes, depending on the complexity of the unit.

- Testing and Final Checks (10-15 minutes): After reassembling the air conditioner, the technician will turn the system back on and check its performance. This includes verifying that the unit is cooling effectively, checking airflow, and ensuring that no leaks or issues are present. This stage generally takes around 10-15 minutes.
How Long Does It Take?
Given the breakdown of the process, a typical aircon chemical wash can take anywhere from 1.5 to 3 hours for a standard residential unit. However, the time can increase depending on the factors mentioned above. For larger, commercial, or more complicated systems, the process can take 4-5 hours or even longer.
Conclusion
An aircon chemical wash is an essential service that helps maintain the efficiency and longevity of your air conditioner by thoroughly cleaning internal components. While the process can vary in time depending on factors such as the size of the unit, the level of contamination, and the complexity of the system, most chemical washes take between 1.5 to 3 hours for a typical residential unit. By understanding the steps involved and the factors that can influence the duration, you can have realistic expectations for how long the process will take and ensure your air conditioner is properly maintained for optimal performance.
