Why is my Dimplex DC10RCDH not cooling efficiently?

If your Dimplex Air Conditioner isn't operating efficiently, check the following: Close the curtains if the air conditioner is in direct sunlight. Ensure windows and doors are closed. Clean the filters if they are dirty. Remove any blockages from the air inlets or outlets. Lower the set temperature if the room temperature is below it.
