    Why does my Acson international ADB350B3 Blower compressor operate continuously?
    • P
      Paul DixonAug 5, 2025
      If your Acson international Blower's compressor runs non-stop, it could be due to a dirty air filter. Try cleaning it. Alternatively, the temperature setting might be too low during cooling, so try increasing it. Or, if it's heating, the temperature might be too high, so try lowering it.

      Joshua DavisAug 9, 2025
      If you find condensation on the front air grille of your Acson international Blower, it's likely due to air humidity or a temperature setting that's too low after the unit has been running for a while. To resolve this, increase the temperature setting and set the unit to operate at a high fan speed.

      riggsrebeccaAug 18, 2025
      If your Acson international Blower's airflow is too slow, or the room isn't cooling enough, several factors could be at play. The air filter might be dirty, or doors and windows might be open. Also, the air suction and discharge of both indoor and outdoor units may be clogged or blocked. Lastly, the temperature setting might not be low enough.

    Why Acson international Blower compressor does not operate immediately?
    • B
      Bryan ThomasAug 22, 2025
      If your Acson international Blower doesn't start immediately, it might be due to a built-in protection against frequent starting. Please wait 3 to 4 minutes; the compressor should start on its own.
