- Choose the correct unit size for your household need.

- If cooling more than one room, install split unit as it is more energy efficient than window models.

- Clean the air filters regularly. A dirty filter blocks the flow of air and causes the compressor to run longer.

- When using air conditioning, close the windows and door to keep the cool air within the room.

- Set the temperature above 23 degree. The lower the temperature, the higher the consumption.

- Invest in an energy efficient model. The higher initial cost will be repaid with lower monthly operating cost.
