    Why does my Acson international AMC125B Blower compressor operate continuously?
    • D
      Dustin NicholsAug 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.

      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.

    Why is the airflow too slow in my Acson international AMC125B?
    • D
      Darius HarperAug 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.

      Beth ColeAug 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.
