Best Way To Clean Aircon
Cleaning your air conditioning (AC) machine is important for better cooling, energy efficiency, and healthier air. Here’s a step-by-step guide for cleaning a typical window-type or split-type air conditioner at home.
🧰 What You’ll Need:
-
Screwdriver
-
Vacuum cleaner (with brush attachment)
-
Soft brush or toothbrush
-
Fin comb (optional)
-
Mild soap or detergent
-
Spray bottle or hose (for outdoor unit)
-
Dry cloth or microfiber towel
🧊 For Window-Type AC:
1. Turn off and unplug the unit
Safety first. Always disconnect power before cleaning.
2. Remove and clean the front panel
-
Unscrew or unclip the front grille.
-
Wash it with warm soapy water. Let it dry completely.
3. Clean or replace the air filter
-
Slide out the filter (usually behind the front panel).
-
Wash with soap and water.
-
Dry it fully before reinstalling.
4. Vacuum the evaporator coils (inside coils)
-
Use a soft brush or vacuum brush attachment.
-
Be gentle to avoid bending the aluminum fins.
5. Clean the condenser coils (back of the unit)
-
If accessible, gently vacuum or spray with a hose (only if it’s fully unplugged and outdoors).
6. Drain water from the base (if needed)
-
Some units have a drain hole—clear it of any clogs using a stick or straw.
7. Reassemble and test the unit
❄️ For Split-Type AC (Indoor Unit):
1. Turn off the power at the circuit breaker
Always turn off the breaker before touching the indoor or outdoor unit.
2. Open the front panel
-
Gently lift the panel.
-
Slide or pop out the filters.
3. Wash the filters
-
Use mild soap and water.
-
Dry completely before putting back.
4. Clean the evaporator coil
-
Use a soft brush or coil cleaner spray.
-
You can also use a no-rinse AC coil cleaner spray (available at hardware stores).
5. Wipe the fan blades and panel
-
Use a dry or damp cloth.
-
Be gentle around electronics.
🌬️ For the Outdoor Unit (Condenser):
1. Turn off the power at the breaker
Make sure no electricity is flowing.
2. Remove leaves, dust, or debris
Use a vacuum or your hands.
3. Spray the fins and coils
-
Use a garden hose at low pressure (not a pressure washer).
-
Spray from the inside out to push dirt away.
4. Straighten bent fins (optional)
Use a fin comb to gently straighten them.
