How Much Electricity Does an AC Use? UP Running-Cost Guide (2025)
One of the most common questions before buying an AC is: how much will it add to my electricity bill? The honest answer is that it depends on the model, usage and your tariff — but you can estimate it easily. Here's a simple running-cost guide for UP homes.
The Simple Formula
Electricity is billed in units (kWh). To estimate cost:
Units per day = average power drawn (kW) × hours used
Daily cost = units per day × your electricity rate per unit
Your exact rate per unit depends on your discom and slab in Uttar Pradesh, so check a recent bill for the figure that applies to you.
An Illustrative Example
A typical 1.5 Ton inverter AC draws roughly 0.8–1.5 units per hour depending on the model, thermostat setting and room conditions. As an example, at about 1 unit per hour running 8 hours a day, that's around 8 units per day. If your rate were around ₹7 per unit (used here only as an example — yours may differ), that's roughly ₹56 a day, or about ₹1,500–₹1,700 a month of heavy use. A 5-star inverter model lands at the lower end; an older fixed-speed unit runs higher.
What Affects Your AC's Running Cost
Star Rating
Higher star ratings use less power for the same cooling. See AC star rating & energy savings explained.
Inverter vs Fixed-Speed
Inverter ACs adjust their compressor and typically use less electricity over a season. Read Inverter vs Non-Inverter.
Thermostat & Usage
Each degree lower significantly increases consumption — 24–26°C is a comfortable, efficient range. Good insulation, clean filters and shaded windows all help.
How to Cut Your AC Bill
Choose a higher-star inverter AC, set 24–26°C, use the timer and sleep modes, service it before summer, and consider a convertible model to right-size cooling. For the full picture, see our AC Buying Guide for North India and the AC Buying FAQ.

Frequently Asked Questions
How much electricity does a 1.5 ton AC use per hour?
Roughly 0.8 to 1.5 units per hour depending on the model, star rating, thermostat setting and room conditions. A 5-star inverter model sits at the lower end.
How can I reduce my AC electricity bill?
Choose a higher-star inverter AC, set the thermostat to 24 to 26°C, use timer and sleep modes, clean the filters and keep the room well insulated.
Do inverter ACs really save electricity?
Yes. Inverter ACs vary compressor speed instead of switching fully on and off, which typically lowers consumption over a cooling season.
