  Amber GarnerAug 4, 2025
  Several factors can impact the cooling performance of your Fujitsu Air Conditioner: * Check if the air filter is dirty. * Ensure that the intake grille or outlet port are not blocked. * Verify that the thermostat is set correctly. * Make sure no windows or doors are open. * If it's during the day, close the curtains to block direct sunlight. * Reduce the heat sources in the room, such as heating apparatus or computers, and also consider the number of people present. * Check if the unit is set to SUPER QUIET operation, as this mode might reduce cooling power.

  Paul NobleAug 21, 2025
  Your Fujitsu Air Conditioner might not start immediately due to these reasons: * If the unit was recently stopped and restarted, the compressor has a 3-minute delay to prevent fuse issues. * If the power supply plug was recently disconnected and reconnected, the protection circuit activates for about 3 minutes.

  During Cooling or Dry operation, a thin mist from your Fujitsu Air Conditioner is normal. It's caused by room air rapidly cooling as it exits the unit, leading to condensation.

  Your Fujitsu Air Conditioner may produce some noise during normal operation: * You might hear water flowing in the piping during and shortly after operation. * The sound of coolant flowing may be noticeable for the first 2-3 minutes after starting. * A slight squeaking can occur due to the front cover expanding and contracting with temperature changes.
