. Yes, in a "preventative maintenance" service visit many thorough and experienced techs will proactively measure the capacitance of the capacitor while the unit is already opened to see if it may be leaking and close to failure and replace it proactively. Of course that can be abused but so can anything if your tech is a real a-nole. It can also be done yourself with a proper inexpensive multi-meter if one is into that type of nerdy stuff and wants to save a $150 service call by replacing a $8 part themselves. Been doing that for many years as well as the air handler fan cap (less susceptible to failure)
