I did realised that whenever the difference between amb and preset temp is less than 2 degrees, the a/c would blow out warm air. However if the difference is more than 2 degrees is fine.
For example, recently outside temp is ard 25 and set temp is 24 I'm getting wram air. Worst of all recently even if the difference is more than 2 degrees, at my pevious preset of 24 I'm still getting warm air.
