Window air conditioners give you the cooling power to stay comfortable even in very hot weather without the need for expensive central air conditioning systems.

A window air conditioner can be a great idea for someone who lives in a smaller dwelling, such as an apartment or small home, and doesn’t require the whole house to be cooled at once. It usually doesn’t take up much space, and can be installed quite easily on most windows.

These units have the advantage over fans, which after some time begin to circulate the same, stale air that is no longer cool. But using a more efficient cooling system comes at a price – a hefty one, if you don’t choose your AC unit wisely.

Do window AC units use a lot of electricity?

This depends on a number of factors, which include: the size of the unit, its BTU, the length of time it’s on, and its wattage. In general, a regular window air conditioner – i.e. one that is not low wattage – could end up drawing a lot of electricity.

For this reason, it’s important to consider the wattage of the device before making your purchase, as this could save you a great deal of money in the long run.

How many watts does a window air conditioner use?

Let’s think of these in terms of size. For larger units, you’d expect anywhere from 1300 – 1500W. For medium units, 1000 – 1300W. For smaller units, around 800 – 900W.

Low wattage, smaller window air conditioners, however, tend to be a much more energy efficient option. These units use an average of 500 – 700 watts, and are a great choice for those who want to keep costs as low as possible.

Note: wattage isn’t everything – you also have to consider the BTU (what is BTU? Find out here). If you have a very large room to cool down, for example, then a smaller, lower watt unit might not be enough.

Below you’ll find a list of our top 5 energy-efficient window AC units, all coming in at 700 watts or under, and all requiring minimal installation on your part. So no need to hire someone to do the job for you.

Are window ac units efficient?

Window ac units can be very efficient, and save you a lot of money on your electricity bills. They use only a fraction of the electricity that a central air system uses, making them a far better choice for people living in smaller homes.

It’s important to remember, however, that you should always consider the size of the room/s you wish to cool, as buying an unnecessarily large unit would cancel out any energy saving you could potentially achieve with this type of AC system.
