How many units of electricity does 1 ton AC consume every hour? Know the complete arithmetic before buying

1 Ton AC: As soon as the heat increases, the first thought that comes to mind is to buy an AC. But along with cold air, the electricity bill can also increase rapidly. Therefore, before buying a 1 Ton AC, it is important to understand how much electricity it consumes every hour and how much impact it will have on the monthly bill.

What does 1 ton AC mean?

First of all, know that 1 ton does not mean weight but cooling capacity. 1 ton AC gives approximately 12000 BTU per hour of cooling which is considered sufficient for a small room (approximately 100-120 square feet). But its power consumption depends on many things like star rating, inverter or non-inverter technology and room temperature.

How many units consumed per hour?

Generally, a 1 ton non-inverter AC can consume about 0.9 to 1.2 units (kWh) of electricity per hour. That means, if you run it for 8 hours every day, then about 8 to 9 units of electricity can be consumed in a day.

Whereas the consumption of 5-star inverter AC is less. This can be limited to an average of 0.6 to 0.8 units per hour as the inverter technology adjusts the speed of the compressor as per the need.

How does the monthly bill increase?

Suppose your AC runs for 8 hours daily and consumes an average of 1 unit per hour. So approximately 240 units of electricity can be spent in a month. If the rate per unit is Rs 7, then the bill for AC alone can be around Rs 1680. In this the consumption of other home appliances is added separately.

What factors change expenses?

Power consumption does not depend only on tonnage. If the room is in sunlight, doors and windows are open or the temperature is set at 18 degrees, then the AC will work harder and consume more electricity. Consumption can be reduced by setting the temperature at 24-26 degrees.

What to look for before buying?

Don’t just look at the price while buying an AC. Be sure to check the star rating, inverter technology and annual energy consumption. The 5-star inverter model, which may seem expensive initially, can reduce electricity bills in the long run.
