Why does my AC unit make a loud noise when it shuts off?

The compressor is the part of your outdoor unit that pumps refrigerant to and from your indoor unit. It’s the same for a compressor with a broken spring. When the air conditioner turns off, the pump loses momentum, which can cause it to knock against the case of the compressor and create a banging or slamming noise.

Gurgling – If there is air trapped in your water heating pipes, you will hear a gurgling or a sound like water rushing thru the pipes. Old furnaces rarely made running water or gurgling noises because there was no condensation or liquid involved. Today, newer and high-efficiency furnaces do produce condensation.
