Mastercool air conditioner
When it goes on it makes a vibration sound, almost like wind blowing thru it. Seems like after awhile it isn't a constant sound, the sound then comes & goes

If it is indeed a true vibration, it could be a number of things. I have seen bad bearings do this off and on as the cooler runs. Could be something going wrong with the blower motor. There are several things that need to be checked to properly evaluate the problem you are describing.
