Why does my AC pulsate?
The pulsating noise you hear is most probably the AC compressor hitting something. Alternatively, refrigerant wires might also be a cause of the air conditioner making loud pulsating noises. If they are too close to a wall, they might be vibrating and hitting the wall repeatedly, generating pulsating sound.
How do I reduce the noise from my neighbors air conditioner?
Use a sound blanket: Applied to fencing or other frame, a sound blanket effectively muffles noise, reducing its unpleasant effects for home occupants and neighbors alike.

How do I know if something is wrong with my AC?

Why is my air conditioner surging?
If the air conditioning is not performing well, the engine might be surging because the system is undercharged or overcharged. If it is overcharged, the load imposed by the compressor will be excessive. If it is undercharged, the AC pressure switch may be cutting the compressor on and off in rapid succession.
Why is my air conditioner making a loud humming noise?
AC Humming Noise A humming sound generally isn’t serious, but it still signals that something inside your air conditioner is off. Loose parts and refrigerant piping can cause vibration and, if left unchecked, can lead to a more serious maintenance issue. Sometimes humming or buzzing noises point to electrical problems.
