Air-conditioners consume a lot of electricity as they are common in offices and run for long hours. To reduce consumption of electricity, the follow steps should be followed;
- Buy efficient air-conditioners. Look out for the yellow label and the black stars. The more the stars, the more efficient the application, no label no good!
- The room should be well sealed and well curtained to avoid warm air entering the room through vent and conduction.
- If you are going out for more than 30 minutes, the air conditioners should be turned off.
