Abnormal system noise is often connected to incorrectly assembled components. If the
compressor is noisy at a certain speed, for instance, and the noise disappears when the
speed increases or decreases, there is probably nothing wrong with the compressor itself.
The difference between the pressure on the suction side and the pressure side also affects
the level of noise. A compressor with low suction makes more noise than a compressor
with high suction. Likewise, a compressor with high high-pressure makes more noise be-
cause it puts more load on bearings, etc.
