Energy Saving Tips

1. Regular Maintenance
Clean the air filter regularly and have your air conditioner inspected annually. Regular aircon maintenance may extend the life of your equipment and help you to save money by lowering your energy bills. Poorly maintained air conditioners can waste a tremendous amount of energy. A clogged filter will also impair the performance of the unit.

2. Optimum interior temperature
The most optimum interior temperature is 25 degrees C ~ 28 degrees C. It is economic and desirable for your health to keep the temperature difference below 5 degrees C between the interior and exterior. Each degree Celsius that the temperature set point raised represents an energy saving of at least 10%.

3. Using a fan
Use an interior fan in conjunction with your window air conditioner to spread the cooled air more effectively through your home without greatly increasing your power use.

4. Switch on and off
Switch on aircon units 30 minutes after the start of office hours, switching it off 30 minutes before closing of office hours.

5. Refrigerant level
Check and replenish refrigerant levels as needed.

6. Turn off exhaust fans
Put off the exhaust fans while the aircon units are in operation.

7. Keep opening closed
To prevent conditioned air from escaping, keep windows, doors and any other opening closed.

8. Installing window unit
Install window-type air-conditioners at the highest accessible place.

9. Air intake and outlet
Do not block the air intake and outlet of the unit. If they are obstructed, the unit will not work well, and may be damaged.

10. Direct sunlight
Do not let direct sunlight into the room. Use sunshades, blinds or curtains. If the walls and ceiling of the room are warmed by the sun, it will take longer to cool the room.

11. Undersize aircon
Do not Install an under size aircon. Ensure that the aircon unit is properly sized for your home. Operating a unit, which is either too large or too small, is highly inefficient. It is also more energy efficient to install a split unit if you are cooling more than one room.

12. Heat source
Do not place lamps or TV sets near your air-conditioning thermostat. The thermostat senses heat from these appliances, which can cause the air conditioner to run longer than necessary.
