Have you ever had a window air conditioner that was just too big for the window that you wanted to install it into if it were sitting horizontally.

But you realize that if you were to turn it on its side you can make it work.

But even though it seems like the perfect solution, there are a few reasons that make the solution not quite as genius as it seems.

Can you install a window air conditioner on its side?

Unfortunately No. The main problem with installing a window air conditioner on its side is the the compressor. The compressor is the main mechanical part that makes the air conditioner work. And It is meant to sit in a specific upright position.

Window air conditioners are designed to be installed in a specific orientation, typically with the front of the unit facing outward and the back facing inward.

Turning it on its side can cause the lubricating oil in the compressor to flow into the refrigerant lines,

which can cause damage to the compressor. And in turn, cause the window AC do not cool efficiently.

And even though there are window air conditioners that have compressors that can sit in any position,

If you were going to buy a new window air conditioner, there are different styles of window ACs that are meant to sit in their windows.

Another thing, is that window air conditioners create condensation which is made to drain out of a specific hole.

Turning the air conditioner on its side could potentially make the drainage system less effective, which also may result in water leaks and additional damage to the AC unit.

Is there any time you can use a window air conditioner on its side?

Some window air conditioners have compressors that are designed to be able to sit sideways.

If you were in the market for a window air conditioner, seeking out this type of air conditioner may be a good ideal.

But remember that there are different types of window air conditioners that are made for different types of windows,

And a vertically sliding window type of window AC would probably be a better solution if you have yet to decide which type of window air conditioner you want.

In some cases, manufacturers may provide instructions for installing a window air conditioner on its side,

But it’s important to remember that this is not just an alternative to sitting it horizontally.

The air conditioner must be specifically designed to be able to sit it on its side.

So unless you have a specific type of window air conditioner with specific instructions on how to install it on its side,

The best money is not to do it. Because you will eventually be throwing away the money that you put into the window AC in the first place.
