Set the thermostat to a moderate and comfortable temperature, ideally around 24-26°C (75-78°F).
Clean or replace filters every 1-3 months, schedule annual professional check-ups, and ensure the unit is free from obstructions.
Ensure vents are unobstructed to allow free airflow throughout the room.
Use fans to circulate cool air and close curtains or blinds during the hottest part of the day to keep the heat out.
Keep doors and windows closed when the AC is running to maintain a sealed environment and maximize efficiency.
