Toddler proofing window AC’s?

How are you toddler proofing window ACs?

We have them in all bedrooms and a big one in our great room. Our almost 16m old loves to play with them. Buttons, the side flap things, the airflow part, etc... No matter how much we tell him no touching, redirect him, etc he runs back over and plays with them.

I’m most worried about the one in his room. We are transitioning him out of his crib into a big boy bed right now and I don’t want him to be able to mess with it while he’s in there unsupervised. The room has a baby gate and is fully baby-proofed besides the window AC.

The cord/socket is babyproofed with a box over the plug. It’s really just him messing with the controls, filter, side cover things or pushing the thing out of the window that I’m most worried about.

What have you guys done?

Thanks!!
