Tips
Change electric company to a lower rate provider.
When looking through mini blinds you should see the ground not the sky.
When getting home lower the temp in steps.. if you keep your house at 80 when you are away and 74 when you are there, drop it to 77 and let it cool down before dropping it down to 74. The house cools down faster!
Put some shade on your outside unit if it is in full sun.
Put solar screens up.
Put window tint on your windows, makes it a little darker but helps.
Good insulated curtains.
Replace incandescent light bulbs with compact Fluorescent Bulbs, if you have the old shop light style bulbs in the garage.. throw them and the fixtures out.
Plant trees on the West, South, and East sides of your house.
Turn off your computer and monitor when not in use.
Air dry dishes.
Wash only full loads of dishes and clothes.
Use ceiling and other fans and turn the thermostat up, turn fans off when gone.
Change AC air filters every month!
AC stays at 73 when home.. 79 when away.
