4. Wear gloves and a mask to avoid dust inhalation.

5. Never touch electrical wiring or circuit boards.

Safety first - always.

Step-by-Step Guide to Clean a Split AC at Home

Step 1: Open the Indoor Unit Panel

• Gently lift the front panel of the indoor unit.

• Most split AC panels open easily without tools.

• Keep the panel open securely.

You will now see the air filters inside.

Step 2: Remove and Clean the Air Filters

This is the most important part.

How to Clean Filters:

1. Carefully slide out the filters.

2. Shake off loose dust.

3. Wash under running water.

4. Use mild soap if very dirty.

5. Let the filters dry completely in shade (do not use direct sunlight).

Never reinstall wet filters.

Clean filters can improve airflow by up to 30%.

Step 3: Clean the Evaporator Coils

Behind the filters, you?ll see thin aluminum fins ? these are evaporator coils.

Cleaning Process:

• Use a soft brush to remove surface dust.

• Spray AC coil cleaner evenly (if available).

• Let it sit for 5-10 minutes.

• Gently wipe with microfiber cloth.

Avoid using too much water to prevent internal damage.

Step 4: Clean the Blower Wheel (Fan Drum)

The blower wheel accumulates heavy dust over time.

How to Clean:

• Use a brush or small vacuum cleaner.

• Rotate the fan gently to clean evenly.

• Do not apply force.

If the blower is extremely dirty, professional cleaning may be required.

Step 5: Clean the Drain Pipe

Clogged drain pipes cause water leakage from AC.

Cleaning Method:

• Locate the drain pipe outside your home.

• Use mild water pressure to flush out blockage.

• If needed, use a thin flexible wire to remove dirt.

Ensure water flows freely after cleaning.

Step 6: Clean the Outdoor Unit (Condenser)

The outdoor unit also needs attention.

Steps:

• Turn off main power.

• Remove leaves, dust, and debris.

• Use a soft brush to clean fins.

• Gently rinse with water (avoid high-pressure water).

Do not bend the condenser fins.

Step 7: Reassemble and Test

• Reinstall completely dry filters.

• Close the front panel securely.

• Turn on the main power supply.

• Run AC in cooling mode.

Check:

• Airflow strength

• Cooling performance

• Any unusual noise

If everything works smoothly, your cleaning is successful.
