Split AC Energy Saving Tips

Want to make the most of your energy-efficient split AC? Start by setting the temperature at 24–26°C it’s the sweet spot for comfort and savings. Always keep doors and windows closed while the AC is on, and use thick curtains to block direct sunlight. Clean your filters every two weeks; clogged filters force the AC to work harder. Use the energy-saving mode or eco mode if available, and switch to fan mode during milder weather. Installing a ceiling fan helps circulate cool air evenly, reducing strain on the unit. Also, avoid placing heat-emitting devices near the AC’s thermostat. With these smart habits, your split AC will not only cool faster but also consume far less power.
