I have air conditioners for normal up and down windows. But my windows slide side to side. how do I install?

Question

I want the insallation to be safe against breakins.

Answer 1

I would use plywood to fill the space above the A/C unit and you can use a block of wood to keep the window from being able to slide from the outside.

Answer 2

There is three was this can be done.

1). Cut a hole in the side of your house that the unit will fit in.

2). Change the window.

3). Install central air.

Answer 3

Strong timber surrounds on a base that is fixed to the window, make it a feature like a picture frame.
