    Why is my Daikin Air Conditioner not cooling well?

      Poor cooling or heating performance in your Daikin Air Conditioner can stem from several causes: a dirty or clogged air filter (clean it), an obstacle near the air inlet or outlet (remove it), open doors or windows (close them), or the unit running at low speed (select medium or high fan speed). Also, air inside the heat exchanger can affect performance, so you may need to contact the installer.
