Don’t make more heat. Delay chores that produce heat and moisture until the cooler parts of the day or evening. Limit dishwashing, laundering and cooking on hot, humid days. These activities make your room more uncomfortable and require your air conditioner to work harder and consumes more power.
Turn off electronics you are not using. Don’t leave electronics, such as televisions, stereos and computers, on if you don’t need them – they produce heat. Extra heat requires more energy to power the air conditioner and increases cooling costs.
