We live in Sta Rosa, Laguna NCR of Luzon. Our bedroom 1HP window A/C is on 24/7. Our previous bill for March was P7,900 then the following current bill for April went up to P9,900 when the temperature has gone up recently. Oh well, that's the price we pay for our creature comfort we can't do without.
My wife also uses her electric washer/dryer twice a week and she uses our electric stove most of the time, propane is just for backup.
Our 10 yr old 1 HP (our backup A/C for our bedroom and 2HP for downstairs is the split-type A/C, which is in the shop for cleaning and servicing and it will cost a pretty penny when it's all done.
Next year we plan to replace everything with the inverter type A/C.
