4. Turn Your Fan into an Air Conditioner
Another easy way to cool your home without air conditioning is to place a bowl of ice or a frozen milk jug in front of one or more fans.
5. What’s hot in your home?
It’s one thing to keep hot air and sunlight out; it’s another to identify the appliances in your home that generate heat. If you aren’t at home during the day, it is easier to simply shut off as many electric appliances as possible. If you spend more of your day at home, try to use heat-generating appliances only during the coolest part of the day.
Keeping your electronics on a power strip provides a quick way to “power-down” before leaving for the day.
7. Light Bulbs
Change incandescent bulbs for cooler fluorescent bulbs. Turn off lights when not in use.
