How much energy does an ac window unit use.

Maximizing your use of a window ac unit. First determine the amps drawn by the unit. 9 000 btu a c units are recommended for rooms that are 350 400 square feet this average applies to both window and split units. Electricity states a window unit uses anywhere from 500 to 1440 watts to run while a 2 5 ton central unit about the size for a typical 1 500 to 2 000 square foot home uses about 3 500.

1500w unit for comparison spends 1 5 kwh of electricity per hour. If central air conditioning isn t an option for your home or apartment finding the right window unit can help keep you comfortable in the warmer months without breaking the bank. And as you discovered the answers depend on both the efficiency of the appliance and external factors that may be out of your control. A good estimate for a medium sized window or wall air conditioning unit is 900 watts.

The smaller models use around 1 400 watts or 5 000 btu hr. Given that an average price of 1 kwh in the us is 0 1319 you can save quite a bit if you invest in an above average energy efficient air conditioner. Power cost because you are billed for units of kilowatt hours you need to estimate how long the unit will run. How much does a window unit cost.

This will depend on the unit s size and seer rating. The higher the eer number the more efficient your air conditioner is. Larger 10 000 btu units that will cool up to 500 square feet are generally priced from 200 to 400. Eer is a measurement of how many btus the unit uses for each watt of power consumed.

For example we will use a 16 seer air conditioner. Mid sized portable air conditioners use an average of 2900 watts per hour. The standard eer for most air conditioners is set at 10 0. The electricity usage of these units generally is less than that of a central ac.

Window air conditioners start at about 100 for a small 5 000 btu unit that will cool up to 200 square feet. To determine how much energy your air conditioner consumes and how much does it cost to run your ac you can estimate it using energy regarding your unit and plugging it into a formula. For example a 1000w ac unit spends 1 kilowatt hour of electricity per hour. The power consumption of 9 000 btu air conditioner units ranges from 800 900 watts if a 9 000 btu a c unit consumes more than 900 watts it is inefficient and you should look for a better model.

In this post you learned how much electricity does a window ac use and how much does it cost to run a window ac unit.
