1: Clean or Replace the Air Filter Regularly
Why Cleaning the Air Filter is Important

2: Keep the Coils Clean
Why Coil Maintenance is Essential
Your evaporator and condenser coils in your window AC unit offer heat exchange. The coils become dusty and dirty, which reduces the cooling ability of the unit, leading to increased energy usage.
How to Clean the Coils
- Turn off the unit and remove the power cord.
- Remove the front cover and locate the evaporator coil inside the unit.
- Clean the dust and dirt using a soft brush or vacuum cleaner.
