How Many Watts Does A Window Air Conditioning Unit Use

The department of energy energy star rating is given to window air conditioners that rate better than 11.

How many watts does a window air conditioning unit use. Check the product manual. So how do you find out how many watts does a window ac use. Your unit may have different ratings. One 10 000 btu air conditioner may use 900 watts of electricity while another one uses 1 000 watts.

The wattage of 5 000 btu air conditioner units averages 446 to 580 watts most of the units assessed for this average were window units as 5 000 btu split units are uncommon. 5 000 btu air conditioners are recommended for rooms less than 200 square feet ideally less than 150 square feet. Once the motor is running steadily the amperage drops and the wattage usually is around 1500. That works out to the following figures for popular sizes.

That s how you can easily estimate that 5 000 btu ac units use 500w of energy. A rule of thumb to estimate how many watts of energy different air conditioners use is to take the btu number and divide it by 10. For a small bedroom a 5 000 btu window unit should only use 450 watts a mid size 8 000 btu ac should use fewer than 715 watts. The total watts all depends on how energy efficient the manufacturer made the appliance.
