Before you decide on your choice of air-conditioner, it is useful to know the following energy-saving tips from the NEA website:

1. The air-conditioning unit achieves cooling by removing heat from the room, consuming electricity in the process. Thus, reducing the amount of heat gained by the room will reduce the amount of electricity consumed for air-conditioning. Consider using sun-shading devices, blinds or solar control film to keep out heat gained by the room through windows.

2. The size, or cooling capacity, of air-conditioning units is usually specified in terms of Btu/hr or kW. (1 kW = 3410 Btu/hr) Ensure that the air-conditioning unit is properly sized to meet the amount of cooling required, as oversized or undersized air-conditioning units can cause reduced comfort and operate inefficiently.

3. Multi-split units are generally more energy efficient than separate single-split/ window units in air-conditioning multiple rooms simultaneously. Consider a multi-split units if you usually require air-conditioning in more than one room.

4. The thermostat senses room temperature to regulate the operations of the air-conditioning unit. Avoid placing lamps, TV sets, or other heat generating appliances near the air-conditioning thermostat, which may cause the air-conditioning unit to operate longer/harder than necessary.

5. The energy consumption by the air-conditioning unit increases with the difference between the room and outdoor temperatures. Set your thermostat as high as comfortably possible. You may wish to consider thermostat setting of 25°C.

6. Dirty air filters impede airflow, leading to increased energy consumption. Check the air filters once a month and clean or replace them as necessary.

7. Besides the air filters, the condition of other components of an air-conditioning unit (such as the refrigerant, pipes and motors) also affects its efficiency. You may also wish to consider regularly servicing your air-conditioning units.

8. Direct sunshine on the air-conditioning unit's outdoor heat exchanger decreases its efficiency. Consider shading the air conditioner where necessary, but do not block the airflow.
