  1. In most typical homes and offices, the air-conditioner is the most energy consuming appliances compared to any other electrical appliances especially in tropical countries where summer is all year round and outdoor temperatures are soaring high. Similarly with reverse cycle air-conditioner (heat pump), it also consumes lots of energy to warm up homes and offices in seasonal countries during winter. Therefore, majority of electricity consumptions comes from the cooling and heating of the surroundings by air-conditioners.

    Other cooling and heating electrical appliances such as the refrigerator, freezer, dishwashers, washing machines and water heaters also consumes lots of energy. For dishwashers and washing machines, majority of the energy consumed is used to heat up the water that is used in the washing process.

  2. Reducing any wear and tear can help pro-long most products' life. To maintain your air-conditioner's product life and to operate effectively and efficiently, you should have your air-conditioner checked and serviced regularly throughout its years of service according to the specifications of the manufacturer. If the air-conditioner's service and maintenance is neglected, there could be a decline in the performance of the air-conditioner and an increase in the energy consumption resulting to a higher electricity bill.

    To improve the efficiency of the air-conditioner, routinely replace or clean the filters. A dirty and clogged air-conditioner filter will block normal airflow into the air-conditioner and allow dirt to be collected at the evaporating coil which will impair the coils heat absorbing capabilities resulting to a lower efficiency level.
