How Much Energy Does A Window Unit Air Conditioner Use

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.

How much energy does a window unit air conditioner use.

Does an old air conditioner use more electricity as it ages. This will depend on the unit s size and seer rating. 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. First determine the amps drawn by the unit.

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. 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. Making cents of this data.

On the smaller side you ll find usage of about 500 watts per hour while larger units use 1440 watts. 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. 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. A central air unit uses more energy to cool your home.

Window air conditioner energy usage. Window blinds should be closed on windows that face the sun to reduce the amount of heat that enters a room. 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. 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.

Eer is a measurement of how many btus the unit uses for each watt of power consumed. Before talking about the amount of energy used up by air conditioning it is important to know how they work. 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 standard eer for most air conditioners is set at 10 0.

Now unless you re looking to reduce carbon emissions your primary concern when it comes to energy usage is. For example we will use a 16 seer air conditioner. A medium sized window air conditioner uses 900 watts per hour.
