If you are planning to buy an air conditioner and are unsure whether to choose a 1.5-ton window AC or a 1.5-ton split AC, understanding their power consumption can help you make a better decision. Here is a detailed comparison based on 3-star rated models.

Power Consumption Comparison

1. 1.5 Ton 3-Star Window AC

• Total consumption: 1204.98 units (in 1600 hours)

• Per hour consumption: 0.753 units

• Cost per hour (at ₹7 per unit): ₹5.27

2. 1.5 Ton 3-Star Split AC

• Total consumption: 975.26 units (in 1600 hours)

• Per hour consumption: 0.609 units

• Cost per hour (at ₹7 per unit): ₹4.26

Key Difference

The split AC consumes less electricity per hour compared to the window AC. This results in lower running costs over time. On average, a split AC can save around ₹1 per hour, which becomes significant with regular use.

Why Split AC is More Efficient

Split ACs are generally more energy-efficient due to:

• Advanced compressor technology

• Better cooling distribution

• Improved energy optimization

Final Verdict

A 1.5-ton window AC consumes more electricity, while a 1.5-ton split AC is more energy-efficient and cost-effective in the long run.

Buying Advice

Before purchasing, always check the energy rating and annual electricity consumption of the model, whether it is from Voltas or any other brand. This will help you avoid higher electricity bills later.

Conclusion

If your priority is saving on electricity bills, a split AC is the better option. A window AC may have a lower upfront cost, but it generally leads to higher electricity expenses over time.
