Saving Electricity as the cost inceases

For central &Split AC, install a programmable thermostat with a built-in timer.

For window unit AC's, just buy a plug-in timer from a home improvement store.

Either way, set the timer or thermostat to turn off about the time you leave for the day, and to turn back on a half hour before you get home. Contrary to popular belief, this does NOT use more electricity than having the AC constantly maintain a cool temperature; it uses less.

You can get programmable thermostats and plug-in timers from your local home improvement store. (Programmable thermostats come with instructions, but it's a quick job for an electrician if you're not comfortable doing the installation yourself.) Plug-in timers comes in different prices and there are more expensive models with more features.

It's a myth that leaving the AC on while you're away at work uses less energy than turning it on when you get home. Think about it: Heat constantly penetrates your home, and that's what your AC removes. If you turn on the AC when you get home, then your AC has to remove the accumulated heat only once. If you leave it on during the day, your AC must repeatedly remove heat that enters your home.

You might think that there's no difference, because your house should absorb the same amount of heat either way. Not true. With the AC off, at some point your house will be so hot that it can't absorb any more heat. But with the AC on, your house will always be cool enough to absorb more heat -- and you'll be paying to remove that heat, over and over again.

2) Increase the temperature of your air condition. This will also helps you to save electricity in your office or home. Make sure your windows are tinted or curtained to maintain the cold air in your offices and home.

3) Third but not least, use fan and open your windows. use some mosquito coils or spray before you sleep. It may help you to save some penny in your pocket. ;)
