that is, assuming he aircons are always on 'cool'. and we know that many aircons go on 'fan' when the room is cool enough.

it really helps a lot, if the room is small and insulated from sunlight heat and other heat sources.

i have a 2.5 hp aircon, cooling a room whose walls are heated effectively by the sun during the daytime.
the aircon is turned on for about 12 hours , at night.
my meralco bill, including everything else in the house, is about 10k.
Napunta ako sa ganyang deep dive computation last year.. Kung naaalala nyo yung delayed 3 months Meralco Bill.. Eh ang init din nun kaya nag-24 hours kami ng aircon.. Tapos surprise, surprise!! Ang laki ng bill namin... Na akala sa una nag-over si Meralco sa computation nila.. Hindi naman pala.. Nag-compute muna ako meter reading.. Tapos inisip ko baka dinaya nung nag-basa ng kuntador.. Ayun nag-compute ako.. Tama pala hahahahahaha [emoji28]
Kaya ni timer ko na ang off and on para sure 19 hours lang... 4:30 AM mamamatay, 9:00 AM sisindi..
