How to Clean Split Air Conditioner: Step-by-Step Maintenance Guide

How to Clean Split Air Conditioner

Your split air conditioner works hard to keep you cool during scorching summers, especially in cities like Karachi, Lahore, and Islamabad. But over time, dust, dirt, and moisture can build up in the indoor and outdoor units, affecting cooling efficiency and air quality. Learning how to clean split air conditioner regularly helps improve performance, reduce electricity bills, and extend the life of your AC.

In this step-by-step maintenance guide, we’ll show you how to clean your AC safely and effectively—even if you’re not a technician.

Why Cleaning Your Split AC Is Important

A dirty air conditioner can:

• Cool less efficiently
• Consume more electricity
• Circulate dust and allergens
• Lead to water leakage or bad smells
• Cause long-term damage to parts like the compressor or PCB board

Regular cleaning ensures your split AC—whether Gree, Haier, Dawlance, Kenwood, or TCL—runs smoothly when you need it most.

What You’ll Need

• Dry cloth or microfiber towel
• Vacuum cleaner or soft brush
• Mild soap and warm water
• Spray bottle or coil cleaner (optional)
• Screwdriver (for outdoor unit cleaning)
• Bucket and gloves

How to Clean Your Split Air Conditioner (Step-by-Step)

🔹 Step 1: Turn Off the Power

Before starting any cleaning, turn off the AC from the remote and main power source to avoid any electrical hazards.

🔹 Step 2: Clean the Indoor Unit

➤ Open the Front Panel

Lift the front cover gently. Most split ACs open easily with light pressure.

➤ Remove and Wash the Air Filters

Slide out the filters and vacuum or rinse them with soap and water. Let them dry fully before reinserting.

➤ Clean the Evaporator Coil

Using a soft brush or coil cleaner spray, gently clean the evaporator coils behind the filters. These collect moisture and dust, which can reduce efficiency.

➤ Wipe the Louvers and Panel

Use a damp cloth to wipe down the blades (louvers), panel, and surrounding plastic parts.

🔹 Step 3: Clean the Outdoor Unit

The condenser unit outside your home expels hot air. If it’s clogged with dirt or leaves, your AC may overheat or cool poorly.

➤ Clear Surrounding Debris

Remove any plants, plastic bags, or dirt around the unit.

➤ Open the Top Grill (If Needed)

Use a screwdriver to access the fan and coils (only if you’re comfortable doing so).

➤ Brush and Spray the Condenser Coils

Use a soft brush or garden hose (not high-pressure) to rinse away dirt. You can also use a coil cleaning spray for deeper cleaning.

➤ Clean the Fan Blades

Wipe dust off the fan blades using a dry cloth or soft brush.

🔹 Step 4: Check for Drain Blockage

Locate the drain pipe near the indoor unit. If it’s clogged, water may leak inside your room. Use a vacuum or blow air through it to clear any blockages.

🔹 Step 5: Reassemble and Power On

Once everything is clean and dry:

• Insert the filters
• Close the front panel
• Switch the AC back on
• Run it for 10 minutes to check airflow and cooling

How Often Should You Clean Your Split AC?

• Every 2–3 weeks: Clean the air filters
• Every 3–4 months: Clean indoor & outdoor coils
• Every 6–12 months: Schedule professional service

If you live in dusty areas  you may need more frequent cleaning.

Pro Tip: Use Inverter ACs for Better Efficiency

Inverter split ACs from Gree, Kenwood, TCL, and Haier adjust power based on room temperature, reducing wear and saving electricity. But even inverter ACs need regular cleaning to maintain their performance.
