Do not rely on air conditioner on daily basis. I know and I understand that heat is unbearable. Hot weather makes me sick too.
On days where weather is ok, switch it to fan instead of an air conditioner. You might not get use to it initially but I assure you that you will get use to it in no time. You will be very surprise that if you do a total switch, you may be saving about S$50.00 per month (base on Singapore context).
Thus, use more fan then air-con. Save the Environment, save yourself.....oops....I tot it's "save the cheer-leader, save the world" ????? :P
