A 1.5 ton split AC with a 5-star rating consumes approximately 840 watts per hour. If you run the AC for the entire night (about 8 hours), it will use 6.4 units of electricity, resulting in a monthly bill of around 1500 rupees. On the other hand, a 1.5 ton AC with a 3-star rating consumes more electricity, potentially leading to a monthly bill of around 2000 rupees.
The Importance of Temperature Settings
Proper temperature settings on the AC also play a crucial role in saving electricity. Many people set the temperature to 18-20 degrees Celsius, which increases electricity consumption. Setting the temperature to 24-25 degrees will keep your room comfortably cool and reduce electricity usage.
