They're noisy because they are inefficient.

It's probably both noisy and inefficient if it's made really cheap, but is that causation true?

But still more efficient than any ceiling fan

Not really comparable since ACs change the air temperature, while fans just move air.

The real reason they are noisy is the only thing between you and the compressor is a sheet of metal.
