The Mr Cool DIY 3rd Gen ductless mini-split A/C units have a very annoying beeping sound every time they are turned on or off. In this video, I show how to remove the speaker without damaging anything so that you can change your mind later if you want.
Side note: I prefer to run mine with the Cielo Home app using the eSaver mode. Doing so, you can set a temperature range where the device turns on if the room gets too hot and turns off after it's been cooled. Obviously, the opposite can be set when heating in the winter.
