      If your Daewoo Air Conditioner isn't cooling enough, ensure all windows and doors are closed to prevent warm air from entering. Remove any heat sources from the room. Check the exhaust air hose to make sure it's properly connected and not blocked. Also, the temperature setting might be too high, so decrease it. Finally, a blocked air filter can restrict airflow, so clean the air filter.
