Air Conditioner buzzing humming

Comfort-Aire split unit - model AMW30, about 12 years old

Greetings all,

My split AC unit began humming/buzzing about a year ago (see youtube link below)

It still cools properly.

Any ideas as to the cause?

Welcome to the forums.

It's hard to tell in a video because the camera doesn't always catch the sound the same way.
It sounds louder than normal in the video but I don't hear any noticeable problem.
It doesn't sound like the fan is running there.
