How much electricity does an AC consume per hour?

A 1.5-ton AC typically consumes 1.2-1.5 kWh per hour. Inverter ACs are more efficient and consume 30-50% less electricity than non-inverter models.

How to reduce AC electricity bill?

Set temperature to 24-26°C, use ceiling fans, ensure proper insulation, clean filters regularly, and choose energy-efficient inverter ACs.

What is the difference between inverter and non-inverter AC?

Inverter ACs adjust compressor speed based on cooling needs, consuming 30-50% less electricity than non-inverter ACs which run at fixed speed.

How much electricity does a 1.5 Ton AC use?

A 1.5 Ton AC typically consumes around 1.5 kW (1500 watts) of electricity per hour. If used for 8 hours daily, it would consume 12 kWh of electricity per day, resulting in approximately 360 kWh monthly consumption.

Are inverter ACs more efficient?

Yes, inverter ACs are significantly more efficient than regular ACs. They use variable speed compressors that adjust cooling capacity based on room temperature, consuming 30-50% less electricity compared to non-inverter ACs.

What's the best way to reduce AC power usage?

To reduce AC power usage: Set temperature to 24-26°C, use ceiling fans for better air circulation, clean filters monthly, ensure proper insulation, use timer/eco mode, and avoid frequent on/off cycles.

How accurate is this calculator?

Our calculator provides estimates based on standard power consumption patterns. Actual consumption may vary based on factors like room size, insulation, outside temperature, AC efficiency, and usage patterns.

Does room size affect AC electricity consumption?

Yes, room size significantly affects AC consumption. A properly sized AC for your room will work more efficiently. An undersized AC will run continuously, while an oversized AC will cycle frequently, both leading to higher electricity bills.

Which AC type is more energy efficient?

Split ACs are generally more energy efficient than window ACs. Split ACs have better insulation, quieter operation, and often come with inverter technology that significantly reduces power consumption.

AC Power Consumption Guide

Understanding how different AC types consume electricity

Tonnage Guide

1 Ton ≈ 1000W, 1.5 Ton ≈ 1500W, 2 Ton ≈ 2000W. Choose based on room size.

Inverter Efficiency

Inverter ACs use ~40% less electricity than regular ACs due to variable speed technology.

Star Ratings

5-star ACs are most efficient, consuming 40% less electricity than 1-star ACs. Higher star ratings mean lower electricity bills and better environmental impact.

Summer Usage

Summer usage is typically 30% higher due to increased ambient temperature.
