Why is my Fujitsu Inverter Halcyon ASU24CL1 Air Conditioner cooling poorly?
- R
  Roberta LeeJul 29, 2025
  Poor cooling performance can occur if the air filter is dirty, the air conditioner’s intake grille or outlet port is blocked, the room temperature settings (thermostat) are not correctly adjusted, a window or door is open, bright sunlight enters through a window during cooling operation, there are heating apparatus and computers inside the room, or too many people are in the room, or if the unit is set for SUPER QUIET operation. Check these conditions to improve cooling.

Why is the airflow weak or stops in my Fujitsu Inverter Halcyon ASU24CL1?
- M
  Melissa FisherAug 7, 2025
  Weak airflow or the Fujitsu Air Conditioner stopping can occur during Dry operation, when the unit is monitoring the room’s temperature, during SUPER QUIET operation, or in monitor AUTO operation. In these modes, the fan operates at a very low speed.

  Jeremy DodsonAug 11, 2025

Richard AndrewsAug 15, 2025
Why is there noise heard from my Fujitsu Inverter Halcyon ASU24CL1 Air Conditioner?
- C
  Christopher MaddoxAug 15, 2025
  The sound of water flowing in the Fujitsu Air Conditioner’s piping may be heard during operation and immediately after stopping the unit. Also, noise may be particularly noticeable for about 2 to 3 minutes after starting operation (sound of coolant flowing). During operation, a slight squeaking sound may be heard, resulting from minute expansion and contraction of the front cover due to temperature changes.
B
Brian GrossAug 20, 2025
Why does my Fujitsu Inverter Halcyon ASU24CL1 Air Conditioner emit mist or steam?
- M
  Melissa GreenAug 20, 2025
  A thin mist may be seen emitted from the Fujitsu Air Conditioner during Cooling or Dry operation. This results from the sudden cooling of room air by the air emitted from the air conditioner, resulting in condensation and misting.

Why does my Fujitsu Inverter Halcyon ASU24CL1 smell?
- J
  James CunninghamAug 25, 2025
  Some smell may be emitted from the Fujitsu Air Conditioner indoor unit. This smell results from room smells (furniture, tobacco, etc.) which have been taken into the air conditioner.
