Help me settle a discussion. Is it better to put an aircond compressor on an exposed ledge or wall (better air circulation at night, but in full sun during the day) or on a covered balcony (cooler during the day, but somewhat restricted airflow at night).

In our case, the airconds would be running at night only (unless hazy weather necessitating closed windows).

And if the balcony has maybe 2 compressors running at the same time, will the balcony become too hot to sit comfortably?

Thanks!

Nowadays inverter compressor where got hot like conventional runing hot like no tomorrow, even after wash cloth and put over few minute there is dryer, recent inverter type may runing with weather condition, when too hot will be spin motor like JET sound after cooling day would run in low speed.. From the hot air for exhaust out also become less n warm only.
