Step-by-Step Guide to Cleaning Your LG Air Conditioner Filter

The air filter is the first line of defense for your LG window AC unit. It traps dust and airborne particles before they enter the system. A dirty filter restricts airflow, making your unit work harder. Cleaning it regularly is perhaps the easiest and most impactful maintenance task. This is the part I clean most often.

Most manufacturers recommend cleaning the filter every two to four weeks. If you have pets or allergies, you might need to clean it more often. Check your LG unit’s manual for specific recommendations. For more detailed instructions on filter cleaning, you can review our guide on how to clean a window AC unit filter.

Locating and Removing the Filter

Finding the filter on your LG window AC unit is usually simple. It is typically located behind the front grille. Some models have a pull-out tab or clips. Others require you to unlatch the entire front panel. My LG unit has a simple slide-out design.

Follow these steps:

Turn off and unplug the unit: Ensure the unit is completely powered down and disconnected from the wall. Safety first!
Locate the front grille: This is the part that faces into your room.
Open or remove the grille: Refer to your LG manual if you are unsure how. It usually involves pulling tabs or unscrewing a few small screws.
Slide out the air filter: Most LG window units have a reusable mesh filter. It slides out easily once the grille is open or removed. Note its orientation for reinstallation.

Washing and Drying the Filter

Once you have the filter removed, cleaning it is straightforward. This step removes trapped dust and debris. I find this part very satisfying, as I can see all the dirt come off.

Here is how to wash and dry your LG air filter:

Shake off loose debris: Take the filter outside and gently shake it to remove larger dust particles. You can also use a vacuum cleaner with a brush attachment for this.
Rinse with cool water: Place the filter under a faucet or use a garden hose. Rinse it from the clean side (the side that faces the room) to push dirt out.
Apply mild soap (optional): For heavily soiled filters, mix a few drops of mild dish soap with water. Gently scrub the filter with a soft brush. Rinse thoroughly until no suds remain.
Allow to air dry completely: This is important. Do not put a wet filter back into your unit. Lay it flat on a clean towel or hang it to dry in a well-ventilated area. Drying can take several hours. Make sure it is bone dry before proceeding.

Reinstalling the Clean Filter

Reinstalling the dry filter is the final step for filter maintenance. This is quick and easy. Make sure it goes back in the correct way.

Check filter orientation: Ensure you are inserting the filter in the same direction it was removed. There might be an arrow indicating airflow direction.
Slide the filter back into place: Gently push it into its designated slot. It should fit snugly without bending.
Reattach the front grille: Secure the grille or panel you removed earlier. Make sure all clips or screws are fastened.
Plug in the unit: Once everything is back in place and secure, you can plug your LG air conditioner window unit back into the power outlet.

Regular filter cleaning will significantly improve your unit’s performance. It is a quick task with big benefits.

Deep Cleaning Your LG AC Unit’s Coils and Fins

After cleaning the filter, the next crucial step is tackling the coils and fins. These components are vital for heat exchange. Dirty coils hinder your LG unit’s ability to cool effectively. This part requires more attention than just the filter.

There are two sets of coils: the evaporator coils (inside) and the condenser coils (outside). Both need regular cleaning. A fin comb helps straighten bent fins, which can also block airflow. Cleaning the coils can greatly improve your unit’s efficiency. For broader guidance, consider our article on how to clean coils on a window AC unit.

Accessing Evaporator Coils (Indoor)

The evaporator coils are located inside your LG window unit, behind the air filter. They absorb heat from your room’s air. To access them, you will need to open the unit’s casing. This might involve more screws than just removing the filter.

Unplug the unit: Always start by disconnecting power.
Remove the front grille and filter: As done in the previous section.
Carefully open the outer casing: Consult your LG unit’s manual for specific instructions. You might need a screwdriver. Some units have side panels or a top cover that lifts off. Be gentle, as plastic parts can be fragile. You might also consider if you need to clean your window AC unit without removing it.
Locate the evaporator coils: They look like metallic fins arranged in rows. They will be behind the area where the air filter sits.

Cleaning Evaporator Coils

Once exposed, the evaporator coils can be cleaned. They are delicate, so handle them with care. This process helps your unit transfer heat more effectively.

Vacuum loose dirt: Use a vacuum cleaner with a soft brush attachment. Gently vacuum the surface of the coils to remove dust, lint, and pet hair. Be careful not to bend the fins.
Apply coil cleaner: Purchase a specialized no-rinse evaporator coil cleaner from a hardware store. These cleaners are designed to dissolve grime and can be left on.
- Spray the cleaner evenly over the coil surface.
- Follow the product instructions for application and drying time.
- The cleaner will drip into the drain pan below.
Wipe gently (optional): If coils are very dirty, you can gently wipe them with a damp cloth after applying the cleaner. Avoid harsh scrubbing.

Cleaning Condenser Coils (Outdoor)

The condenser coils are on the outside part of your LG window unit. They release the heat absorbed from your room. These coils are exposed to outdoor elements, so they can get very dirty with leaves, dirt, and even insects. Cleaning them improves the unit’s ability to expel heat.

Access the condenser coils: Depending on your unit’s design, you might need to partially slide the unit out of the window frame or remove additional casing screws to expose the back or sides. Ensure it is still securely supported. If you installed your LG AC unit in the window, you might recall how its outdoor components are positioned. Sometimes, knowing how to install an LG air conditioner in a window can help you understand how to access different parts for cleaning.
Vacuum external debris: Use your vacuum with a brush attachment to remove leaves, bugs, and large dirt particles from the condenser coils and the fan blades in this section.
Spray with water: Gently spray the condenser coils with a garden hose. Spray from the inside out if possible, to push dirt outwards. Do not use high pressure, as this can bend the fins.
Apply coil cleaner (optional): If coils are very greasy or dirty, use an outdoor coil cleaner. These often require rinsing. Follow product instructions carefully. Ensure no cleaner gets on electrical components.
Rinse thoroughly: If using a cleaner that requires rinsing, ensure all cleaner is washed off.
Allow to dry: Let the coils air dry completely before reassembling the unit.

Straightening Bent Fins

Over time, or during cleaning, the delicate aluminum fins on both evaporator and condenser coils can bend. Bent fins restrict airflow, reducing efficiency. A fin comb helps correct this.

Purchase a fin comb: These inexpensive tools have various teeth sizes to match different fin spacing.
Gently comb the fins: Align the comb with the fin spacing. Slowly pull it through the bent areas to straighten them.
Work carefully: Do not force the comb, as this can cause further damage. This step significantly improves airflow.

Cleaning the Drain Pan and Fan Blades of Your LG Window AC

The drain pan and fan blades are other important areas to clean. The drain pan collects condensation. If left dirty, it can become a breeding ground for mold and mildew. The fan blades circulate air, and dirt on them reduces efficiency. I always find some grime in the drain pan.

This part of the cleaning helps prevent odors and improves air circulation. It ensures your LG unit runs smoothly and without unwanted smells. Taking time for these areas truly pays off.

Clearing the Drain Pan

The drain pan, also called the condensate pan, collects water from the evaporator coils. This water usually drains outside. However, blockages or standing water can lead to mold and unpleasant odors.

Locate the drain pan: It sits directly beneath the evaporator coils. You will see water collected in it, especially if the unit has been running recently.
Remove standing water: Use a wet/dry vacuum or sponges to soak up any standing water in the pan.
Clean the pan: Use a mixture of warm water and a few drops of mild dish soap, or a diluted bleach solution (1 part bleach to 16 parts water), to clean the pan.
- Scrub away any slime, mold, or debris.
- Rinse the pan thoroughly with clean water.
Clear the drain hole: Make sure the drain hole is clear of blockages. Use a small brush or pipe cleaner if needed. Ensuring the drain is clear helps prevent water overflow. This also helps prevent common issues like mold from a window air conditioner.

Wiping Down Fan Blades

Your LG window AC unit has one or more fans. These fans move air across the coils. Dust and grime can accumulate on the fan blades. This buildup reduces the fan’s efficiency and balance.

Access the fan blades: You will see a large fan, usually behind the coils, when the casing is open.
Wipe the blades: Use a damp cloth with mild soap or an all-purpose cleaner. Carefully wipe down each fan blade.
Be gentle: Do not bend or damage the blades. Ensure they are clean and free of sticky residue.
Allow to dry: Let the blades air dry completely before proceeding with reassembly.

Addressing Mold and Mildew

Mold and mildew often grow in damp areas, like the drain pan and on coils. They cause a musty smell and can affect air quality. If you find mold, address it properly.

Identify moldy areas: Look for black, green, or fuzzy spots.
Use a mold cleaner: Create a solution of equal parts white vinegar and water, or use a specific mold and mildew remover. Do not mix bleach and ammonia-based cleaners.
Apply and scrub: Spray the moldy areas and let the solution sit for a few minutes. Use a stiff brush (like an old toothbrush) to scrub away the mold.
Rinse and dry: Rinse the area with clean water if using a non-no-rinse cleaner. Ensure the area dries completely to prevent regrowth. This is key to a fresh-smelling unit.

Maintaining the Exterior Casing and Grille of Your LG Unit

While internal components are important, do not forget the visible parts of your LG window AC unit. The exterior casing and front grille collect dust and dirt. Keeping them clean improves the unit’s appearance and helps maintain airflow. This also ensures your unit looks good in your home.

This step is quick and simple. It completes the cleaning process, leaving your unit looking fresh. I like seeing my unit clean inside and out.

Wiping Down Surfaces

The main body of your LG window AC unit, including the sides, top, and back, can get dusty. A quick wipe-down removes surface grime.

Use a damp cloth: Dampen a clean cloth with warm water. You can add a small amount of mild all-purpose cleaner to the water.
Wipe all accessible surfaces: Gently wipe down the entire exterior casing. Pay attention to any textured areas where dust might settle.
Dry with a clean cloth: After wiping, use a dry, clean cloth to remove any moisture. This prevents water spots and ensures the unit is dry.

Cleaning the Front Grille

The front grille is where air enters your room. It often has slats or a design that can trap dust. Cleaning it ensures unobstructed airflow and a tidy appearance.

Remove the grille (if applicable): If your LG unit’s grille is easily removable, take it off for a more thorough cleaning.
Wash or wipe:
- If removable: You can wash it in a sink with warm, soapy water. Use a soft brush to get into crevices. Rinse thoroughly.
- If not removable: Wipe it down with a damp cloth. Use a vacuum brush attachment to remove dust from the slats. A cotton swab can help reach tight spots.
Dry completely: Allow the grille to air dry, or wipe it dry, before reattaching it.

Ensuring Proper Airflow

Beyond just cleaning, make sure nothing obstructs the airflow pathways. This includes ensuring the unit is properly positioned in the window.

Check vents: Make sure no curtains, blinds, or furniture block the front grille or the side vents of the unit.
Clear external obstructions: Ensure nothing blocks the condenser coils on the outside. Remove any leaves, twigs, or debris that might accumulate around the back of the unit. Clear space around your unit allows it to breathe.

Keeping the exterior clean not only makes your LG unit look better but also supports its overall performance by ensuring proper ventilation.
