Why is my Eco Air ECO902SQN Air Conditioner not cooling or heating room very well?
- A
  Andrea AnthonyAug 1, 2025
  If your Eco Air Air Conditioner (Cooling/heating models only) isn't cooling or heating the room well despite airflow, it might be due to an inappropriate temperature setting. Ensure you set the temperature correctly. A blocked air filter could also be the cause, so clean it. Make sure that doors or windows are closed. Additionally, check for any blockages at the air inlet or outlet of either the indoor or outdoor unit, clear any obstructions, and then restart the unit. Finally, the compressor's 3-minute protection might be active; simply wait.

What to do if my Eco Air ECO902SQN does not start?

  Sara DavenportAug 15, 2025
  If your Eco Air Air Conditioner isn't starting, it could be due to a power cut. Wait for the power to be restored. Also, check that the unit is securely plugged into the wall receptacle. A blown fuse could also be the culprit, so replace the fuse if necessary. If you're using the remote, the battery might be exhausted, so try replacing it. Finally, the timer setting might be incorrect; either wait or cancel the timer setting.
