Landed
5 persons
Rm700+

i only use ONE AC at a time, very rarely both at the same time
i service almost every 6 months. and yes without anything else running, my fridge clocks in at almost RM100/month just by itself, and i have no freakin idea why. Not sure on the wattage though, it's a shitty Electrolux.
usually only 1 AC is on at a time, i would say 6-8 hours for the 2hp, and 10 hours for the 1.5hp
i always service my aircond almost twice yearly. total for both aircond does not even exceed 20 hours per day, see above for breakdown.
I called TNB a few times, they came and check, deemed the meter OK, they also are baffled why my bill is ultra high, they think it's the water heater, i tried almost not using it for 1 whole month, and the bill ended up being cheaper by 10-15 bucks only. So i'm thinking my AC could be the main culprit, or there's some funny business going on with the meter/connection to the meter/i donno what the fuck else.
