Can You Duct a Window Ac

You could use some insulated duct , a register box , and a lot of duct tape . It kind of works. Do not be tempted to use cheaper, uninsulated duct. You will get a lot of condensation on the outside and the air getting to the “other” room won’t be nearly as cold as it could be.

Can I vent a window AC into another room?

You can even vent into another room. The primary goal of venting is to get the hot air coming off the compressor out of the room you are trying to cool. As long as you can accomplish that, then you and your portable air conditioner will have a very happy life together.

Can we change window AC to split AC?

Yes. Many manufacturers use same compressor for window and split AC. However if the piping length is too long or the height difference between indoor and outdoor unit is too much then you have to select a suitable compressor accordingly.
