I'm trying to understand how to avoid swollen electricity bill, particularly on air con.
Folks at my work said to keep it at 24 ~ 25c is the key; his example was keeping your house consistently cooled down to 24 ~ 25c from the morning (even when it's not hot) will reduce the workload of your aircon as it doesn't need to work that hard and when it gets to peak afternoon, the house is already at 24 ~ 25c hence aircon won't work as hard.
is there much accuracy in the above method?
what my colleagues are saying is that, when comparison is done on quarterly basis, purely on aircon:
- running aircon 24x7 at consistent 24-25 centigrade versus running aircon 5 hours (daily) at 19 centigrade
the latter would incur more swollen bill.
what's your thoughts?
