How Much Electricity Does A 1.5 Ton AC Consume In A Day: Air conditioners have become a necessity in many Indian homes, especially during the intense summer months. Among the different options available, a 1.5 ton AC is one of the most commonly used models because it is suitable for medium-sized rooms and offers balanced cooling.
However, many people worry about electricity bills when running an AC regularly. Understanding how much electricity a 1.5 ton AC consumes in a day can help you manage usage and estimate your monthly power costs more accurately. Let’s break it down for you in simple terms so you can easily understand the daily power consumption and what affects your electricity bill.
A typical 1.5 ton air conditioner uses around 0.9 to 1.8 units of electricity per hour, depending on the model and efficiency rating.
For example:
5-star inverter AC: around 0.9 – 1.3 units per hour
3-star inverter AC: around 1.2 – 1.4 units per hour
Non-inverter AC: around 1.5 – 1.8 units per hour
In simple words, if your AC runs for one hour, it typically consumes about 1-1.5 units of electricity on average.

Daily electricity usage mainly depends on how many hours you run the AC. A 1.5-ton AC in India typically consumes between 8 to 14 units (kWh) of electricity per day, assuming 8 hours of usage.
Daily consumption depends on the star rating (5-star vs. 3-star), inverter, room insulation, and temperature settings, generally ranging from 1.2 to 1.7 units per hour.
Electricity rates in India usually range between Rs 6 and Rs 10 per unit, depending on your state and usage slab.
Example:
Daily usage: 10 units
Electricity rate: Rs 7 per unit
Daily cost: Rs 70
Monthly cost (30 days): Rs 2,100
If the AC runs longer hours or if the electricity slab increases, the cost can go even higher.

Several factors determine how much electricity your AC actually consumes.
Star Rating: Higher BEE star ratings mean better energy efficiency. A 5-star AC consumes less power than a 3-star model.
Inverter vs Non-Inverter AC: Inverter ACs adjust compressor speed instead of switching on and off repeatedly. This helps reduce electricity consumption significantly.
Temperature Setting: Setting the AC temperature between 24°C and 26°C can save noticeable electricity compared to running it at very low temperatures.
Room Size: If the room is large or poorly insulated, the AC needs to work harder, which increases power usage.
Maintenance and Filters: Dirty filters or poor servicing can increase energy consumption by 10-20 percent.

Here are a few simple ways to reduce your electricity bill during summer:
Set the temperature at 24-26°C
Use a ceiling fan along with AC for better air circulation
Keep doors and windows closed while running AC
Clean AC filters regularly
Choose inverter or 5-star rated models for better efficiency
These small habits can help reduce electricity usage without compromising comfort.
By choosing an energy-efficient AC and using it wisely, you can enjoy comfortable cooling without worrying too much about high electricity bills.
