1.5 Ton AC Electricity Cost Per Hour in India (Real Power Consumption Guide 2026)
If you are planning to buy a new AC or already using one, you might be wondering:
- How much electricity does a 1.5 ton AC use?
- How much does it cost per hour?
- Will it increase my monthly electricity bill?
In this simple guide, we will explain the real electricity consumption of a 1.5 ton AC in India, how much it costs per hour, and some smart tips to reduce your AC power usage.
How Much Electricity Does a 1.5 Ton AC Consume?
On average, a 1.5 ton air conditioner consumes between 1.2 kWh and 1.8 kWh per hour.
The exact power usage depends on the AC type, energy rating, and usage conditions.
| AC Type | Average Electricity Consumption |
|---|---|
| 1.5 Ton Inverter AC | 1.2 – 1.5 units per hour |
| 1.5 Ton Non-Inverter AC | 1.5 – 1.8 units per hour |
Inverter AC models usually consume less electricity because they adjust compressor speed instead of constantly switching on and off.
1.5 Ton AC Electricity Cost Per Hour
Electricity prices vary across India, but the average cost is around ₹7 to ₹10 per unit.
Let’s calculate a simple example:
- AC consumption: 1.5 units per hour
- Electricity price: ₹8 per unit
Estimated cost per hour = ₹12
This means running your AC for 8 hours daily would cost around ₹96 per day.

Monthly Electricity Cost of 1.5 Ton AC
If you use your air conditioner regularly during summer, here is an estimated monthly cost.
| Daily Usage | Monthly Units | Estimated Cost |
|---|---|---|
| 6 hours/day | 270 units | ₹2000 – ₹2300 |

| 10 hours/day | 450 units | ₹3500 – ₹4000 |
These numbers may change depending on AC efficiency, room insulation, and outside temperature.
Factors That Affect AC Electricity Consumption
Several factors influence how much electricity your AC uses.
- Energy star rating (3 Star vs 5 Star)
- Room size
- Outdoor temperature
- AC maintenance
- Thermostat temperature settings
Best AC Temperature to Save Electricity
The recommended AC temperature in India is 24°C.
Setting the AC at extremely low temperatures like 18°C or 20°C increases electricity consumption significantly.
Using the recommended temperature helps balance comfort and power efficiency.

Here are some simple ways to reduce AC power consumption:
- Keep the thermostat around 24°C
- Clean AC filters regularly
- Use ceiling fans with AC
- Keep doors and windows closed
- Choose inverter AC models for better efficiency
