How to clean air conditioner: Steps and Tips to Follow

‍

Maintaining a clean air conditioner is essential for optimal performance, energy efficiency, and indoor air quality. The cleaning process varies depending on the type of air conditioner, such as split systems, ducted systems, or window units. Generally, the steps involve cleaning or replacing filters, cleaning coils, clearing drainage, and checking electrical components.

Before cleaning, ensure you have the necessary tools and safety equipment. It's important to turn off the power to the unit and consult the manufacturer's manual for specific instructions. According to Energy.gov, you should clean your air conditioner at least once a year, preferably before the start of the cooling season.

While regular cleaning is important, it's part of a broader maintenance routine. Professional servicing goes beyond general cleaning, involving detailed inspections, refrigerant checks, and electrical testing. Here's a list of steps to follow when cleaning your air conditioner:

1. Turn off the power
2. Remove debris from the outdoor unit
3. Clean or replace air filters
4. Clean evaporator and condenser coils
5. Clear the condensate drain line
6. Inspect and clean fan blades
7. Check for wear or damage
8. Reassemble the unit
9. Test the system

Turn off the power to the unit

This step involves shutting off the electrical supply to your air conditioner at the circuit breaker or fuse box. It's important to do this before any cleaning to prevent electrical shock or injury. Always double-check that the power is off by trying to turn on the unit. This step is important as it ensures your safety throughout the cleaning process.

Remove debris from around the outdoor unit

Clear away leaves, twigs, grass clippings, and other debris from around the outdoor unit. Use a soft brush or vacuum to remove dirt from the unit's exterior. Trim any vegetation within a 60cm radius of the unit. This step is important because it allows for proper airflow, which is essential for the unit's efficiency.

Clean or replace the air filter

Remove the air filter from the indoor unit. If it's washable, clean it with mild soap and water, then allow it to dry completely before reinserting. If it's disposable, replace it with a new one. This step is important because clean filters improve air quality and system efficiency. The Australian Department of Industry, Science, Energy and Resources recommends cleaning or replacing filters every few months.

Clean the evaporator coils and condenser coils

Use a soft brush to remove dust from the evaporator coils (indoor unit) and condenser coils (outdoor unit). For stubborn dirt, use a commercial coil cleaner, following the product instructions carefully. This step is important because clean coils improve heat transfer, enhancing the system's cooling capacity and energy efficiency.

Check and clear the condensate drain line

Locate the condensate drain line and check for any blockages. Use a wet/dry vacuum to clear any clogs, or flush the line with a mixture of water and vinegar. This step is important to prevent water damage and mould growth caused by drainage issues.

Inspect and clean the fan blades

Carefully clean the fan blades in both the indoor and outdoor units using a damp cloth. Check for any signs of damage or imbalance. This step is important because clean, well-balanced fans operate more efficiently and quietly.

Check for any visible signs of wear or damage

Inspect all components for signs of wear, corrosion, or damage. This includes checking insulation on refrigerant lines, looking for oil stains that might indicate leaks, and examining electrical connections. This step is important for identifying potential issues before they become major problems.

Reassemble the unit and restore power

Once cleaning is complete, carefully reassemble all components. Ensure everything is securely in place before restoring power to the unit. This step is important to ensure the system is ready for operation.

Test the unit to ensure it operates correctly

Turn on the air conditioner and let it run for at least 15 minutes. Check for proper cooling, unusual noises, or odours. This final step is important to confirm that the cleaning process was successful and the system is functioning correctly.
