Why is my Panasonic Air Conditioner not cooling properly?

  Shelley WeaverAug 14, 2025
  If your Panasonic Air Conditioner isn't cooling well, several factors could be the cause. First, a dirty or clogged air filter restricts airflow, so clean it. Second, eliminate any heat sources in the room or reduce the number of people present, if possible. Third, shut any open doors or windows to keep heat out. Ensure there are no obstacles near the air intake or discharge port to maintain good airflow. Finally, lower the thermostat setting for more effective cooling.
