Why is my Fujitsu Inverter Halcyon ASU9RL Air Conditioner cooling poorly?
- A
  Andrew AvilaJul 29, 2025
  Several factors can cause poor cooling performance: * Check if the air filter is dirty. * Ensure that the air conditioner's intake grille or outlet port isn't blocked. * Verify that the room temperature settings (thermostat) are correctly adjusted. * Make sure no windows or doors are open. * If it's during cooling operation, close curtains to block bright sunlight. * Consider if there are too many heat-generating devices or people in the room. * Check if the unit is set to SUPER QUIET operation.

Why is the airflow weak or stopping in my Fujitsu Air Conditioner?
- M
  Mark SmithAug 11, 2025
  Weak or stopped airflow can occur for several reasons: * When heating starts, the fan speed is temporarily low to warm internal parts. * During heating, if the room temperature exceeds the thermostat setting, the outdoor unit stops, and the indoor unit operates at a very low fan speed. Adjust the thermostat higher if needed. * The unit may temporarily stop during heating for Automatic Defrosting (7-15 minutes), indicated by a flashing OPERATION Indicator Lamp. * The fan might operate at a very low speed during Dry operation or when monitoring room temperature. * In SUPER QUIET operation, the fan runs at a very low speed. * In AUTO operation monitor, the fan runs at very low speed.

Why is there noise coming from my Fujitsu Inverter Halcyon ASU9RL Air Conditioner?
- P
  Paul EllisAug 15, 2025
  Various noises can come from your Fujitsu Air Conditioner during normal operation: * You might hear water flowing in the pipes during or immediately after operation. * A slight squeaking sound can occur due to temperature changes causing minute expansion and contraction of the front panel. * During heating, a sizzling sound may be heard occasionally, which is normal during Automatic Defrosting.

Why is my Fujitsu Inverter Halcyon ASU9RL Air Conditioner emitting mist or steam?
- L
  Lori PatelSep 12, 2025
  The emission of mist or steam can occur due to: * During Cooling or Dry operation, a thin mist may appear because of the sudden cooling of room air, leading to condensation. * During Heating, steam may rise from the outdoor unit, and the fan may stop due to Automatic Defrosting.
