Friends, as March progresses, the summer heat has already begun to make its presence felt. To beat the heat, people rely on appliances such as air conditioners, fans, and air coolers. When it comes to the popular choice—the AC—buyers often face a common dilemma: should they opt for a 1.5-ton Window AC or a 1.5-ton Split AC? While both are capable of cooling medium-sized rooms, their electricity consumption and operating costs can differ significantly. Let's dive into the full details.

1. 1.5-Ton 3-Star Window AC

A 3-star rated 1.5-ton Window AC consumes approximately 1,204.98 units of electricity over 1,600 hours of usage.

Electricity consumption per hour: Approximately 0.753 units.

If the electricity rate is ₹7 per unit, the operating cost comes to approximately ₹5.27 per hour.

Window ACs are generally more affordable and easier to install; however, compared to Split AC models, they tend to consume slightly more electricity.

2. 1.5-Ton 3-Star Split AC

A 3-star rated 1.5-ton Split AC consumes approximately 975.26 units of electricity over 1,600 hours of operation.

Electricity consumption per hour: Approximately 0.609 units.

At an electricity rate of ₹7 per unit, the operating cost comes to approximately ₹4.26 per hour.

Split ACs are generally quieter, more efficient, and—in terms of electricity consumption—slightly cheaper to operate.

Window AC vs. Split AC: Which Consumes Less Electricity? Based on the comparison provided above, a 1.5-ton split AC consumes less electricity than a window AC, which means it can help reduce your electricity bills over time.

An Important Tip Before Buying an AC

Before purchasing any air conditioner—whether it is from **Voltas** or any other brand—always be sure to check the annual electricity consumption indicated on the energy rating label and rating chart. The label clearly states how many units of electricity the AC will consume over 1,600 hours of usage.
