New Delhi: As the summer intensifies, an AC becomes a necessity; however, understanding its operating costs is equally important. Typically, a 1.5-ton AC consumes approximately 1 to 1.5 units of electricity per hour.

This consumption varies depending on the type of AC, its star rating, and the ambient temperature of the room. Inverter ACs generally consume less electricity.

Inverter vs. Non-Inverter ACs

If you use a 5-star inverter AC, its average consumption is around 1.2 units per hour. In contrast, older or non-inverter ACs consume more electricity because they frequently cycle on and off. An inverter AC adjusts its operating speed according to the cooling demand, thereby saving electricity.

If an AC is operated for 7–8 hours, it can consume approximately 10 to 14 units of electricity. For instance, if your AC consumes 1.2 units per hour, running it throughout the night would result in a total consumption of about 9–10 units. Consumption may increase further if the temperature is set to a very low level or if the room door is opened frequently.

Assuming an electricity tariff of ₹8 per unit, the cost of running an AC for a single night could range from approximately ₹80 to ₹100.If you use the AC daily, the monthly bill attributed solely to the AC could amount to anywhere between ₹2,500 and ₹3,000.

How ​​to Save Electricity and Money

A few simple tips can go a long way in saving electricity:

• Maintain the temperature between 24°C and 26°C.
• Keep the room properly sealed (doors and windows closed).
• Keep the AC filter clean.
• Run a ceiling fan in conjunction with the AC.

Adopting these small habits will reduce the workload on the AC and subsequently lower electricity consumption. With the right information and a little prudence, you can enjoy the full benefits of your AC without worrying about excessive costs. Smart usage can significantly reduce your electricity bill.
