Not only will we go over how much electricity does a window ac unit use but we ll also reveal how you can figure out the cost it takes to run a window air conditioner each hour.
How much energy does a window unit air conditioner use.
Now unless you re looking to reduce carbon emissions your primary concern when it comes to energy usage is.
This will depend on the unit s size and seer rating.
Thursday june 14 2018 yes an older air conditioning or heat pump system gets less energy efficient as it nears the end of an average lifespan.
We can use mostly the same theoretical factors with a window unit as we did with central air assuming you re running it for eight hours a day at a national average kwh cost of 13 2 cents.
By the end of this post you ll have everything you need to make a well informed buying decision on a new window air conditioning unit.
An air conditioner works in a similar manner to a refrigerator in that a pump and a circuit of tubes create the cooling system.
In other words it is a measurement of how efficient and how much energy your ac unit uses to cool the room.
However window units sip energy compared to relatively massive central heating and cooling systems usually topping out at about 1 440 watts for a powerful ac.
The higher the eer number the more efficient your air conditioner is.
Before talking about the amount of energy used up by air conditioning it is important to know how they work.
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.
First determine the amps drawn by the unit.
Eer is a measurement of how many btus the unit uses for each watt of power consumed.
Window air conditioner energy usage.
For example we will use a 16 seer air conditioner.
On the smaller side you ll find usage of about 500 watts per hour while larger units use 1440 watts.
Converting btus to kilowatt hours a measurement equal to one kilowatt of power consumption per hour you ll find that a 7 500 btu pac consumes about 2 2 kwh a 10 000 btu unit 2 9 kwh and a.
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.
Making cents of this data.
A central air unit uses more energy to cool your home.
Does an old air conditioner use more electricity as it ages.
The standard eer for most air conditioners is set at 10 0.
A medium sized window air conditioner uses 900 watts per hour.
