- Check to make sure nothing is blocking the front of the air conditioner. When the unit is blocked by curtains, blinds, or furniture, the air flow is restricted and cooling performance will be affected.
- Make sure the air filter has been cleaned in the last 30 days. Filter removal and location varies depending on the individual model.
- Check the thermostat setting. The highest setting will provide maximum cooling.
- Consider the temperature of the room when the air conditioner was first turned on. If the room was very hot it will take longer to cool the room. When heat is stored up in walls, furniture, rugs and draperies, it will take longer to cool the room down. Whenever possible, turn the air conditioner on before the room heats up.
- Make sure the air conditioner is properly sized for the room.
