How Much Electricity Does an Air Cooler Use?

If you’re thinking about buying a big air cooler, you’re probably wondering, “Will my electricity bill jump?

The quick answer is no, not by much. In fact, air coolers are one of the most budget-friendly ways to cool down your space.

How much power does a regular home air cooler really use?

Let’s look at the numbers.

  • Smaller coolers like Thermocool’s Mr. Cool → Consume about 100 to 200 watts of electricity. 

  • Medium to large Air Cooler → Consume about 200 to 400 watts of electricity.

  • High-performance or Desert Coolers → Consume about 400 to 600 watts of electricity.

Now, compare that to an AC, which can use anywhere from 1500 to 2500 watts. That’s 5 to 8 times more power! That’s the big difference right there. An air cooler uses just a fraction of the electricity an AC does, but it still gives you strong airflow.

What does this mean for your monthly electricity bill?

Let’s see how much does an air cooler cost. Say you use it for 8 hours a day, this is what your electricity bill will look like:

What Factors Affect the Electricity Consumption of Your Air Cooler?

  1. Motor-Power

All air coolers come with different motors. The higher the wattage, the more power it will consume. This is why desert coolers consume slightly more electricity than personal or power coolers.

  1. Whether or not your cooler is getting necessary maintenance

For instance, if your cooler has dirty cooling pads or the pump has scale buildup on it. Then it may result in higher electricity consumption, because improper maintenance means the cooler has to put in more work to deliver its functions. 

  1. Room size and how well it’s ventilated also affect things

Good airflow means the cooler doesn’t have to work as hard. A well-ventilated room helps an air cooler run efficiently.

  1. And, of course, how many hours you use it

The longer it’s on, the more electricity it consumes. But coolers are still very economical even if you use them for many hours daily.
