I think Good, Bad and Excellent are relative terms.
Let’s clarify these terms on a given situation e.g. 45+ degree Celsius on road temp that’s where AC performance can be truly tested.
Bad: AC is on and you’re still sweating
Good: Temperature is under control... no sweating
Excellent: You can easily feel the chill air and AC is not tripping during idle or high revs
I think swift AC is excellent as per my 2-3 weeks experience
