It doesn’t matter if you chop a little too long from a functional standpoint. However, from an aesthetic sense, it should get about the same width as your cooling system A/C.

Step#2 Identify and mark the center point on the window

Some machines are always willing backward to aid condensation drainage, whereas others do not. Make any necessary changes. Window air conditioners require a slope so that moisture collects in the discharge pipe instead of falling into your room.

Therefore, extend the accordion panels outward to reach the window’s edges and secure them with screws in the lower frame. Pilot holes should be drilled in the bottom sash if they aren’t already there to prevent the wood from breaking. To make pilot holes, use a drill bit that is somewhat smaller than the screw size.

Step#5 To fill up the gaps

Remove the panel frame fully gently pulling it up and off. It’s time to fill in the blanks on this panel frame. Your house would become open to the outside if this does not happen. If your air conditioner arrives with a foam strip then cut it and use it to occupy the gaps; if not, you could purchase one separately.
