I tested 7 modern inverter ACs in peak summer— Here are the ones that kept my power bill under ₹2000

When the temperature outside crosses 45 degrees Celsius, running the AC continuously for hours together becomes unavoidable. While it does help you keep cool and comfortable, it also leads to shockingly monthly high electricity bills that can easily stack up. The solution to this problem isn't turning the AC off but getting a modern inverter AC with energy saving features that give you both long lasting comfort and high energy saving.

In order to find out if modern inverter ACs could actually outsmart the heat and energy meter, I tested some of the best inverter ACs in a standard bedroom. For making the calculation easy to understand, I operated each AC at a steady 24 degrees Celsius for around 8 hours every night and tracked their power drawn using a digital energy meter. Here's what I found out:

The math behind the ₹2,000 bill

An old fixed-speed 1.5-ton AC consumes a continuous 1.5 to 1.8 kW per hour, while a modern 1.5 ton 5-star inverter AC that dynamically slows its compressor down once the room is cooled consumes just 1.05 kW per hour under standard testing.

Delhi's energy calculation

First 200 units: 200 x ₹3 = ₹600

For traditional AC

- Daily Consumption: 1.8kW x 8 hours = 14.4 kWh per day (units)

- Monthly Consumption: 14.4 units x 30 days = 432 units per months

Remaining 232 units for traditional AC: 232 x 6.5 = ₹1,508

Gross Base energy charge for traditional AC: ₹600 + ₹1,508 = ₹2,108

PPAC Surcharge: 17% of ₹2,108 = ₹358.36

Electricity Duty: 5% of ₹2,108 = ₹105.4

Fixed Demand Charge (For a 2 kW load) = ₹20 x 2KW = ₹40

Final bill: ₹2,108 + 358.36 + 105.4 + ₹40 = ₹2,611.76

For inverter AC

- Daily Consumption: 1.05kW x 8 hours = 8.4 kWh per day (units)

- Monthly Consumption: 8.4 units x 30 days = 252 units per months

Remaining 52 units for inverter AC: 52 x 4.50 = ₹234

Gross Base energy charge for inverter AC: ₹600 + ₹234 = ₹834

PPAC Surcharge: 17% of ₹834 = ₹141.78

Electricity Duty: 5% of ₹834 = ₹41.70

Fixed Demand Charge (For a 2 kW load) = ₹20 x 2KW = ₹40

Total bill: ₹834 + ₹141.78 + ₹41.70 + ₹40 = ₹1057.48

This calculation clearly shows that you can save at least ₹1500 by switching from traditional AC to an inverter AC. So, if you are planning to upgrade the old ACs with modern inverter AC, here are top five picks for you.
