How to Clean LG Dual Inverter AC

Cleaning your LG dual inverter air conditioner (AC) is essential for maintaining its efficiency and ensuring that it provides clean and healthy air. Here are the general steps for cleaning your LG dual inverter AC:

Please note: Before you begin, turn off the power to the AC unit by switching off the circuit breaker or unplugging it from the electrical outlet. Additionally, refer to your LG AC’s user manual for specific cleaning instructions and safety precautions, as the process may vary based on the model.

Materials Needed:

  • Screwdriver (for removing the front panel, if necessary)
  • Soft cloth or sponge
  • Mild detergent
  • Water
  • Vacuum cleaner with a brush attachment
  • Fin comb (for straightening bent fins)

Cleaning the Filters:

  1. Open the front panel of the AC unit. This can usually be done by gently pulling the panel towards you. Refer to your user manual for instructions specific to your model.
  2. Remove the air filters from the unit. Depending on your model, there may be one or more filters, such as the pre-filter and the fine dust filter.
  3. Wash the filters with a mild detergent and lukewarm water. Gently scrub them to remove dust and dirt. Do not use harsh chemicals or abrasive brushes, as they can damage the filters.
  4. Rinse the filters thoroughly with clean water until all detergent is removed.
  5. Allow the filters to air dry completely. Ensure they are completely dry before reinserting them into the AC unit.

Cleaning the Inside of the AC Unit:

  1. Use a vacuum cleaner with a brush attachment to remove dust and debris from the interior of the AC unit. Pay special attention to the evaporator and condenser coils, blower, and any other accessible components.
  2. If the condenser coils have bent fins, use a fin comb to straighten them. Bent fins can affect the AC’s efficiency.

Cleaning the Exterior:

  1. Wipe down the exterior of the AC unit with a soft cloth or sponge dampened with water. You can add a mild detergent to the water if needed.
  2. Be gentle while cleaning the control panel and display to avoid damage.
  3. Dry the exterior thoroughly to prevent water from entering the unit.


  1. Reinsert the dry and clean air filters into their respective slots in the AC unit.
  2. Close the front panel and ensure it is securely in place.
  3. Restore power to the AC unit by turning on the circuit breaker or plugging it back into the electrical outlet.

Regular Maintenance:

  • It’s a good practice to clean the filters at least once a month during periods of heavy usage.
  • Consider scheduling professional maintenance at least once a year, especially before the cooling season begins. A qualified technician can perform a more thorough cleaning and inspect the AC for any potential issues.

Remember that proper cleaning and maintenance of your LG dual inverter AC can help prolong its lifespan, maintain its energy efficiency, and ensure better air quality in your home.
