  Patricia DavisJul 31, 2025
  If your Alen Air Conditioner is not cool enough, several factors could be the cause. First, ensure all windows and doors in the room are closed. Remove any heat sources from the room if possible. Check that the exhaust air duct is properly connected and not blocked. Also, verify that the temperature setting isn't too high by decreasing the set temperature. Finally, a blocked air filter can also cause this issue, so clean the air filter.

Why does my Alen C425 power shut off in heating mode?

  Brian WalkerAug 18, 2025
  If your Alen Air Conditioner's power shuts off in heating mode, it is likely due to the automatic overheat protection function. When the temperature at the air outlet exceeds 70°C/158°F, the device will stop. Switch it on again after the unit has cooled down.

  The gurgling sound you hear in your Alen Air Conditioner comes from the flowing of the refrigerant inside the air-conditioner, so it is normal.
