I don't see an AC unit. I see pipes and wire. Nonetheless, here are some ideas on how others have decorated around an AC.

Paint it the same color as the wall. Any controls will need to be left unpainted, but this can greatly decrease the impact of the unit. Hide it beneath a decorative return air grill affixed to a Box Frame that extends from the wall. This will cause the least interference with air flow, and hinges will allow you to access the controls. You can then paint everything to match the wall if you wish. Surround the AC with art so that it is lost in a clutter of interesting things.

Purple farts and unicorn confetti.

ask for it by name.
