We bought a DeLonghi portal air unit in 2019 I believe.

Used it every year between the bedroom and my office for maybe four weeks a year.
TOTALLY WORTH IT.
It will cool off a room to be very comfortable.
You don't need to keep it running, or we didn't. We turned in on 30 minutes before bed, the bedroom was cool when we got in bed, had a timer set for 2 hours.
In the office, I would turn it on mid morning for about 2 hours. The room would stay comfortable a few more hours. Maybe I turned it on towards the end of the work day if the heat became uncomfortable again.
Oh, there is a vent tube you don't see in the photos. [We have something similar to this set up when the AC is being used.](https://www.amazon.de/-/en/Conditioning-Conditioners-Exhaust-Windows-Casement/dp/B0DY79H62K/ref=sr_1_1?crid=2A6PLX2SMC0TA&dib=eyJ2IjoiMSJ9.MtGGRHD6b2soMBjzlJVYBhGjVGN1Eb4V6zQNHxLS3ERuYmM-LMNySkEsdYsm9-2V6D3efNr72aItHVtjK16rDJssiKcrIMUmdmAWvZRHz1V8ZiTqKDpWrzSIb3W4UfKyswAHnP8KtWM8BqK69-YqDdyzGpxkuS-NqvruowcOj29gnoQAtII-lngLtKYf2uJfG2dXHguc_nudDL2DKnGvr4kknSuqvifpy6xvqzKd-H0.D-qGh6owB3VvKU2EoB617YfVPiiHvU0idB-0CtlayRw&dib_tag=se&keywords=Window%2BSeal%2Bfor%2BMobile%2BAir%2BConditioner&qid=1751210293&sprefix=window%2Bseal%2Bfor%2Bmobile%2Bair%2Bconditioner%2Caps%2C118&sr=8-1&th=1)
We used a portable refrigerative air con temporarily (with removable window kit & tubing), which did the job for the master bedroom when we had a newborn (waiting on the ducted installer).
