Larger 10 000 btu units that will cool up to 500 square feet are generally priced from 200 to 400.
How much energy does an ac window unit use.
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.
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.
Particularly large units can exceed the electricity usage of even central air conditioners expending about 4100 watts per hour.
Mid sized portable air conditioners use an average of 2900 watts per hour.
Power cost because you are billed for units of kilowatt hours you need to estimate how long the unit will run.
The standard eer for most air conditioners is set at 10 0.
1500w unit for comparison spends 1 5 kwh of electricity per hour.
For example we will use a 16 seer air conditioner.
Eer is a measurement of how many btus the unit uses for each watt of power consumed.
Check out this post to learn more about air conditioner sizes and how they re measured.
The higher the eer number the more efficient your air conditioner is.
The electricity usage of these units generally is less than that of a central ac.
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.
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.
How much does a window unit cost.
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.
Maximizing your use of a window ac unit.
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.
The smaller models use around 1 400 watts or 5 000 btu hr.
This will depend on the unit s size and seer rating.
And as you discovered the answers depend on both the efficiency of the appliance and external factors that may be out of your control.
Window air conditioners start at about 100 for a small 5 000 btu unit that will cool up to 200 square feet.
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.
