How to use your Air Conditioner efficiently

With energy costs on the rise, ensuring that your air conditioning operates as efficiently as possible is more important than ever. There are many ways to effectively run your air conditioner.

What determines Air Conditioner energy efficiency? Why does it matter?

The Annualised Energy Efficiency Ratio (AEER) rating determines the energy efficiency of an air conditioning unit. A AEER rating measures how much cooling an air conditioner provides relative to the energy consumed and is used to indicate an air conditioner’s total yearly energy consumption. The higher the AEER, the more energy efficient the air conditioner is. Several factors contribute to the AEER rating of an air conditioner, including the type, size, and design. Air conditioners containing advanced technology, such as variable-speed compressors and programmable thermostats, can also improve the energy efficiency of an air conditioner.

2 ways to use Air Conditioners efficiently

  •  

1. Temperature controls

Avoiding making significant and sudden temperature changes is one way to maintain the efficiency of your air conditioning system. Although it can be tempting to rapidly cool or heat your home during the summer or winter, this can result in much higher energy bills. Preparing your home for the season through other methods can help your air conditioning system maintain a consistently appropriate temperature throughout seasonal weather changes. Air leaks and poor insulation can cause your air conditioner to work harder. Seal any gaps or cracks in your home's exterior, add insulation to your attic and walls to keep warm air inside during the winter, and install curtains or shades to keep sunlight out during the summer. It is also advisable to decide on a specific temperature setting for when you're awake and inside the house and a different temperature setting for when you're away from home or asleep. When maintaining a consistent indoor temperature, humidity can be easily overlooked. When the level is too high or too low it can affect your home’s temperature. Luckily, it is easy to control indoor humidity levels with your air conditioning unit. When humidity levels indoors are high, use the dry mode on your air conditioner to lower the humidity and feel more comfortable at the same temperature. This is more efficient than using a cooling mode. Some of the latest air conditioner units utilise smart technology to know the target temperature for your home based on your indoor humidity levels and can even be adjusted remotely or to a set schedule using an application on a smartphone.

2. Check your air filter

Regularly checking your air filter is an essential step in air conditioner maintenance. A dirty air filter reduces the efficiency of an air conditioner because it restricts airflow. This means the air conditioner must work harder to circulate air, which increases power consumption and decreases cooling performance. Additionally, a dirty filter can cause dust and other allergens to circulate the air. We recommend checking your air filter regularly. Cleaning the interior of the unit is also important. If dust accumulates inside the machine, the air conditioner may take more time to cool down and could consume more power. Not cleaning the interior can also cause unpleasant odors from within the machine. For ceiling-mounted air conditioner units, cleaning the external grill and dust filter yourself is possible; however, it is recommended to use a professional air conditioner cleaning company to disassemble and clean the internal parts of the air conditioning unit. In addition, different air conditioning models may have differing cleaning practices, and it is recommended that you consult a specialist if necessary. Finally, after finishing cleaning the indoor unit of the air conditioner some experts suggest selecting Fan Mode for 30 minutes to 1 hour to remove any moisture that may remain within the unit.

Which type of Air Conditioner is right for you?

LG air conditioners offer a range of features to keep your home comfortable. The three types to choose from are as follows:

Which size of Air Conditioner is right for you?

When an air conditioner is too large relative to its surroundings, it can cause constant on/off sequences that result in either overheating or overcooling. This ineffective functioning can cause hot spots throughout your home, leaving some rooms cool and others hot and humid. In contrast, air conditioners that are too small will run for too long, trying to reach the programmed temperature and wasting energy. When choosing the right size air conditioner for your home, you need to know the size of the space you wish to cool. Calculating the room size will help you decide on the ideal air conditioner capacity. The LG Smart Inverter air conditioners are an excellent choice if you're looking for a unit to cool a larger space. These units utilise Smart Inverter Compressor™ technology to cool large spaces quickly and efficiently. The Smart Inverter Compressors allow quicker distribution of cool air and these air conditioner units come with a 10-year warranty* on the compressor for lasting, maximal performance.

*5 year parts and labour + 5 year limited parts warranty on the compressor.

Accurate installation

It is best to entrust a professional technician to install your air conditioner. An expert will know the ideal environment and settings to ensure optimal air conditioner usage.

There are many options to consider when choosing an air conditioner for your home and finding a balance between your comfort and efficiency is not always easy. We hope this article has shared some helpful tips to get you started on your journey.
