AC Electricity Cost Calculator

Don't be shocked by your electricity bill. Calculate the running cost of Split, Window, Inverter, and Non-Inverter ACs based on tonnage and star rating.

AC Power Consumption Guide

Air conditioners are the heaviest load in most homes. Understanding their cost helps you manage your budget without sacrificing comfort.

Inverter vs. Non-Inverter Technologies

Non-Inverter ACs run their compressors at full speed until the room is cold, then turn off. When the room warms up, they blast on again. This "start-stop" cycle consumes huge amounts of power.

Inverter ACs have variable speed compressors. They start high to cool fast, then slow down to a "cruise control" mode to maintain temperature. They don't switch off. This saves 30-50% electricity.

Tips for Saving Money on AC

  • The 24°C Rule: Every degree you raise the temp saves 6% electricity. 24°C is the sweet spot for comfort and savings.
  • Seal the Room: Even a small gap under the door sucks out cold air. Use door draft stoppers.
  • Service Regularly: A dirty filter makes the AC work 15% harder. Clean filters every 2 weeks in summer.

Frequently Asked Questions

Which AC is cheaper to run: 1 Ton or 1.5 Ton?

It depends on room size. If you put a 1 Ton AC in a large room, it will run continuously at max power and never cool effectively, costing MORE than a 1.5 Ton that cools quickly and settles down.

Does "Sleep Mode" save money?

Yes. Sleep mode gradually increases the temperature by 1-2 degrees per hour while you sleep, preventing the room from getting freezing cold and saving significant power overnight.
