First determine the amps drawn by the unit.
How much energy does a window unit air conditioner use.
Before talking about the amount of energy used up by air conditioning it is important to know how they work.
Making cents of this data.
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.
For example we will use a 16 seer air conditioner.
The higher the eer number the more efficient your air conditioner is.
A central air unit uses more energy to cool your home.
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.
Eer is a measurement of how many btus the unit uses for each watt of power consumed.
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.
This will depend on the unit s size and seer rating.
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.
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.
Window air conditioner energy usage.
Does an old air conditioner use more electricity as it ages.
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.
A medium sized window air conditioner uses 900 watts per hour.
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.
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.
On the smaller side you ll find usage of about 500 watts per hour while larger units use 1440 watts.
The standard eer for most air conditioners is set at 10 0.
An air conditioner works in a similar manner to a refrigerator in that a pump and a circuit of tubes create the cooling system.
Now unless you re looking to reduce carbon emissions your primary concern when it comes to energy usage is.
