When it rains, the cooling efficiency actually increases because the rainwater and the drop in outside tempetature helps to cool the ODU which make this heat transfer as efficient as possible.

On a hot day, the reverse happens, the heat transfer becomes less efficient, hence it takes a longer time to cool the room.

That the reason why the room is colder in the early morning even on a hot day.

You can test by having a digital thermometer in the room. On both occasion, you can record how long it takes to cool down the room at determine temperature.

On the side note, your AC may be under power to your room size.

Or is it mind over matter ?

Cheers fellas. Would you recommend any other brand or would it be safe to just stick to Panasonic?
