As temperatures continue to rise, staying comfortable indoors has become increasingly difficult. From ceiling fans and air coolers to air conditioners, people are relying on different cooling solutions to cope with the heat. However, running an air conditioner for extended periods can raise concerns about electricity costs, particularly among middle-income households.
Many people limit their use of air conditioners at night to avoid high electricity bills, often compromising their comfort in the process. However, with a few adjustments to everyday habits, it is possible to maintain a comfortable indoor temperature while managing energy consumption.
Here are some practical ways to make your air conditioner more energy-efficient.
Set the temperature wisely
The temperature setting plays an important role in determining how much electricity an air conditioner consumes. Lower settings require the compressor to work harder and for longer periods, increasing energy use.
According to a recent study cited in the original report, each degree of reduction in the temperature setting can increase electricity consumption by around 6%. Keeping the thermostat at a moderate temperature, therefore, can help reduce unnecessary energy use.
Choose 24°C over 18°C
Setting the air conditioner to 18°C may seem like an effective way to cool a room quickly, but it can significantly increase energy consumption. A setting of 24°C is generally sufficient to maintain a comfortable indoor environment during hot weather.
Instead of lowering the temperature excessively, gradually adjust your nighttime settings to 24°C. This can help maintain comfort while reducing the strain on the air conditioner's cooling system.
Keep doors and windows sealed
An air conditioner works more efficiently when cool air remains inside the room. Open doors, poorly sealed windows, and gaps around frames allow cool air to escape while letting warm air enter.
Make sure all doors and windows are properly closed before switching on the AC. Check for gaps that may need sealing and use curtains to reduce heat entering through windows.
Switch off unnecessary electronic devices
Electronic appliances generate heat while operating, which can increase the cooling load on an air conditioner. Televisions, computers, and other devices can contribute to indoor heat, making the AC work harder to maintain the desired temperature.
Switch off appliances that are not in use before going to bed. This can help reduce unnecessary heat generation and improve cooling efficiency.
Use the timer function
Running an air conditioner throughout the night may not always be necessary. As the room cools down, maintaining the same level of cooling until morning can lead to unnecessary electricity consumption.
Use the timer function to schedule the AC to switch off one or two hours before your usual wake-up time, if the room remains comfortable. This can help avoid excessive cooling and reduce operating time.
With the right temperature settings, proper room insulation, and mindful use of household appliances, you can enjoy a cooler night's sleep without putting unnecessary pressure on your electricity bill.
