Why is my Hiyasu Air Conditioner's cooling performance so poor?
- J
  Jamie WhitneyAug 13, 2025
  Poor cooling performance in your Hiyasu Air Conditioner can stem from several factors. Check if the air filter is dirty or if the intake grille or outlet port are blocked. Ensure the room temperature settings (thermostat) are correctly adjusted. An open window or door can also impact cooling, as can direct sunlight. Finally, consider if there are too many heat-generating appliances or people in the room, or if the unit is set to SUPER QUIET operation.

Why is the airflow weak or stopping in my Hiyasu Air Conditioner?

  david26Aug 20, 2025
  Weak airflow or complete stops in your Hiyasu Air Conditioner can occur for various reasons. When heating starts, the fan speed is temporarily low to allow internal parts to warm up. During heating, if the room temperature exceeds the thermostat setting, the outdoor unit will stop, and the indoor unit will operate at a very low fan speed. The unit will also temporarily stop during the Automatic Defrosting mode, indicated by a flashing OPERATION lamp. The fan may operate at a very low speed during Dry operation, when monitoring the room's temperature, or during SUPER QUIET operation and monitor AUTO operation.

  The mist or steam emitted from your Hiyasu Air Conditioner can be a normal occurrence. During Cooling or Dry operation, it results from the sudden cooling of room air, causing condensation. During Heating, steam from the outdoor unit is due to Automatic Defrosting.

  The noise you hear from your Hiyasu Air Conditioner can be attributed to a few things. During and immediately after operation, it could be the sound of water flowing in the piping. It might also be the sound of coolant flowing, especially noticeable for the first few minutes after starting. During heating, a sizzling sound may be heard due to the Automatic Defrosting operation.
