Very true and can be done. Two problems arise on early compressors--those with the mechanical clutch connections designed for an "on and stay that way" condition are not designed to catch the sudden load repeatedly and frequently & start to slip and overheat in some cases, or the mechanical links break in others. The other condition on early piston type compressors arises where the build up of high side pressure in the system averages when cycled off and then all of a sudden, compressor turns on and the piston has to move against it. If not designed for it, then a tremendous load is applied to piston, valves, and other components and something eventually breaks.
