Is the outside temperature too cold?

Set the Fan Speed control to Turbo or Turbo Cool.

Does the filter need to be cleaned?

Do the condenser coils need to be cleaned?

Is the Power Saver mode turned on?

Are the vents blocked?

If the louvers or vent are blocked, the air conditioner may not cool the room properly. Install the air conditioner in a location where the louvers or vents are free from curtains, blinds, furniture, etc. Also, make sure the louvers or vents are in the open position.

Is the room temperature extremely hot?

If the temperature of the room you are trying to cool is extremely hot allow extra time for the air conditioner to cool off. If there is excessive heat or moisture (open container cooking, showers, etc.) in the room use a fan to exhaust heat or moisture from the room. Try not to use heat-producing appliances during the hottest part of the day.

Is the air conditioner the correct size for the room?

If the air conditioner is not properly sized for your room the air conditioner may not cool the room properly. Check the cooling capabilities of your room air conditioner. Room air conditioners are not designed to cool multiple rooms.
