Why is the airflow too slow or the room not cooling enough with my Acson AWM25J Air Conditioner?
- A
  adrienne84Jul 25, 2025
  If your Acson Air Conditioner isn't cooling well or the airflow is weak, several factors could be at play. First, a dirty air filter can restrict airflow, so try cleaning it. Ensure that all windows and doors are properly closed. Also, check that neither the air suction nor the discharge vents on the indoor and outdoor units are blocked. If they are, repair any clogging or replace faulty components. Finally, verify that the temperature setting isn't too high; try using a lower temperature setting.

  robertarellanoJul 29, 2025
  If the compressor in your Acson Air Conditioner runs non-stop, there are a few things to check. Make sure the air filter is clean because a dirty filter can cause this issue. Also, the temperature setting might be too low if you're cooling, so try increasing it. Conversely, if you're heating, the temperature setting might be too high, so try decreasing it.

  If the airflow from your Acson Air Conditioner smells bad, it could be due to particles like cigarette smoke or perfume that have stuck to the coil. In this case, contact your nearest dealer.

Why doesn't the compressor start right away on my Acson AWM25J Air Conditioner?
- M
  Michael WhiteheadAug 15, 2025
  If the compressor in your Acson Air Conditioner doesn't start immediately after turning the unit on, this is likely due to a built-in protection against frequent starting. Allow 3 to 4 minutes for the compressor to start on its own.
