The basic steps on how to service split AC at home with pressure washer,
Turn off power supply: Switch off the AC from the main power source and unplug it. Never service your split AC while it is connected to electricity.
Prepare the area: Cover nearby walls, furniture, and electrical parts with plastic sheets. Place a cleaning bag or bucket under the indoor unit to collect dirty water.
Open the indoor unit: Lift the front panel and remove the air filters. Take out any detachable parts carefully to access internal components.
Dry clean first: Use a soft brush or vacuum to remove loose dust from filters, coils, and fins. This prevents mud formation when using water.
Clean filters separately: Wash the filters with water and mild detergent. Let them dry completely in shade before reinstalling.
Use pressure washer on indoor unit: Use a low-pressure setting to spray water on the evaporator coil and blower. Avoid spraying directly on electrical parts and PCB. Maintain a safe distance to prevent damage.
Clean the outdoor unit: Spray the condenser coil using moderate pressure to remove dirt, dust, and debris. Ensure proper airflow by cleaning all sides.
Check the drain pipe: Flush the drain pipe with water to remove clogs and ensure smooth water flow.
Let everything dry: Allow the unit to dry completely before reassembling. Moisture in electrical parts can cause damage.
Reassemble and test: Reinstall filters and close the panel. Turn on the AC and check cooling performance.
Regular servicing improves efficiency and extends AC life.
