Setting the temperature a little higher of around 78-80 degrees Fahrenheit , will you save 6 to 8 percent of your cooling costs for each degree above 78, and most people will be comfortable.
Use a ceiling fan or portable fan to supplement your air conditioning. A fan can make you feel three to four degrees cooler (and only costs a half-cent per hour to operate) so you can set your thermostat a few degrees higher and save on cooling costs. Use in occupied rooms since fans cool people, not rooms.
Turn off the air conditioning or set the thermostat up a few degrees when you leave home.
Be sure your air conditioner is not blocked. A free flowing air conditioner operates most efficiently Be sure the return air grill inside your house is not blocked by furniture or other items. Filters should be checked monthly.
When air conditioning is on, keep doors and windows closed Turn off kitchen or bathroom exhaust fans when your air conditioning is operating.
Caulk and weather-strip leaky windows and doors.
Shade your home from direct sunlight. Use shades, drapes, awnings, trees and shrubs to block the hot sun from heating up your home.
If you suspect your air conditioning system is not cooling properly, have it checked promptly. A unit that is having operational problems can cause extremely high bills.
