We pay about 5000 pesos per month and summer and half of that in winter. Three bedrooms with airco, only using two, and not the whole night, in summer about 6 hours, in winter about 3 hours. And another 2-3 hours in the day when the smallest one sleeps. They are inverter airco s with helps a lot SEER 21, 12000 BTU, 15m2 each. The other room has a 18000 btu conventional airco, but that one is hardly used.
Solar heater, gas dryer, electrical water pump, electrical washer (used a lot). One Tv and a few computers. All lightbulb s are low consume or LED and I do bother everyone to switch of lights.
One or two months the bill came 8000 pesos, until I found out the new maid would leave the ironing machine on the whole day, just switching the temperature to the lowest level. If the red light would turn off, for her the ironing machine was off. Since I told her to not do that anymore it went back to normal levels. We live in a 230m2 house, I was afraid the bill would come higher than 10k, but it went actually down a lot compared to what I paid in the apartment I used to live in.
