We have one in an upstairs bedroom from midea, the window slides right between the front and back of the unit and it’s excellent. Our power consumption didn’t increase too terribly much and it’s actually decently quiet.
Not gonna put the model here but just look for U shaped window units. It has little legs that go outside.
Don’t get the inside standing units, they’re massive, loud, power hungry, and most of them are less effective than even the cheap window units.
Huh no kidding
