  If your Daewoo Air Conditioner's cooling or heating isn't working well, several factors could be the cause. Check if the temperature setting is appropriate. Make sure that neither the air inlet nor the outlet is blocked. Also, examine the air filters to see if they are dirty. Verify that the indoor fan speed isn't set too low. Finally, consider whether there are any heat sources present in the room.
