Why is my AUX AM not cooling or heating well?
- JJohnny WillisJul 28, 2025
If your AUX Inverter isn't cooling or heating the room very well even with air flowing out, the temperature setting might be inappropriate; set the temperature correctly. The air filter could be blocked, so clean it. Open doors or windows can also affect performance, so close them. Check if the air inlet or outlet of the indoor or outdoor unit is blocked and clear any obstructions. Also, the compressor's 3-minute protection might be activated; simply wait.
