Air in Pipes

I own a 3-family house. All of the faucets in the house are functioning fine except for the faucet in the top apartment. It spits out water in a machine gun pattern: air-water-air-water and the whole frickin house shakes every time you turn on the faucet. It sounds like something is definitely shaking violently when I turn the water on. Can someone help? what the heck is going on??!! PLEASE!!!

You can get air in water supply lines for several reasons...work on the house plumbing, taps into and work on nearby public water lines, leaking air bladder in a pressure tank if on a well and pump, etc.
Air will usually rise to the highest point in the system. Just run it until it goes away. If that doesn't get rid of it, you may have to find the source.
Good Luck!
