Getting electricity savings out of aircon use

Jun 18, 2019

It is without a doubt that owning an aircon will mean an increase in your monthly electricity bill. Yet, there is a way for you to minimize the cost of the electricity bill with some simple changes!

Here are some useful tips that will help increase aircon efficiency and reduce energy consumption:

1. Choose the right cooling capacity

2. The most important factor you need to consider before buying an aircon is its cooling capacity. Choosing the right capacity depends on the actual size of your room. An underpowered aircon would mean that the compressor will have to work harder to keep the room cold, thereby resulting in an increase in electricity usage.

3. Choosing a higher cooling capacity is not the right choice for a small room either as it will not operate at its optimal efficiency although there is a short lead time to cooling the room. It is worth noting this also increases the room humidity which shortens the aircon’s lifespan.

4. Other factors that will need to be taken into consideration would be ceiling height, direct sunlight as well as the number of occupants.

2. Maintaining an optimal temperature

3. The ideal temperature for comfort and energy-saving would range between 22℃ - 25℃.

3. Ensure your aircon unit is always clean (inside - fan coil unit and outside - compressor)

4. Do not let your fan coil unit and compressor run on a dirty filter. This decreases its efficiency and increases electricity consumption. A dirty air filter slows down the airflow and causes your aircon system to work harder.

   Cleaning the entire system every once in a while and conducting a once a year maintenance is crucial to ensure the longevity of your aircon unit.

4. Choose an inverter aircon system

5. The inverter technology has a similar concept to that of an accelerating car’ it allows your aircon unit to increase or decrease its speed when required. If a compressor is always running at a constant speed, it will consume less energy to reach a stable temperature.

6. In doing the above, the overall reduction in electrical consumption is estimated to translate into 30% - 40% savings!

5. Additional tips

6. The use of a ceiling fan can aid the cooling capacity of an aircon system which in turn, helps to reduce the cost of electricity. Having a ceiling fan can reduce the cost of electricity consumption by at least 5% - 10%!
