My Panasonic 1.5 Inverter is not as cool as the LG 1.5 Non-Inverter in a room in my office ..

And that room in my office is 1/4 bigger than my room which is only small ..

Is it due to my AC is bigger than my room size ?? My room is actually small, apartment room size or condominium room size .. I noticed that my AC's outdoor unit keeps tuning off or the fan that cools the compressor keeps turning off when it reach the set temp which is only 23 'C ..

Does it affect the room temp if the outdoor unit's fan stops after cooling the room rather than in a medium size room where the outdoor unit's keeps on running because the compressor is working at minimum level ??
