  If your NewAir Air Conditioner isn't effectively cooling, first ensure all doors and windows are closed to prevent warm air from entering. Then, check for any heat sources in the room and remove them if possible. Inspect the exhaust hose to ensure it is properly connected and not blocked. Also, make sure the temperature setting isn't too high, and clean the air inlet to ensure proper airflow.

  If your NewAir Air Conditioner is making excessive noise, ensure the unit is placed on a flat, level surface. If the sound resembles flowing water, it is normal and comes from the refrigerant inside the air conditioner.

  If the NewAir Air Conditioner unit does not start when pressing the on/off button, it might be due to a full water tank. Check for a blinking water full indicator light and empty the water tank. Alternatively, if in heating mode, the room temperature might be higher than the set temperature; reset the temperature. If in cooling mode, the room temperature might be lower than the set temperature; in this case, reset the temperature as well.
