Mark, I think what the service tech was getting at was that the air blowing through the condenser (which is the part of the system that gets cold by the refrigeration process and cools the air passing over/through it) is moving too fast and not getting as cool as it would if it took longer to blow through it. [(slower blower, slower air speed) = more cooling.] If the fan is belt driven often times a (split) adjustable shiv (pulley) is used to adjust the RPM of the fan, or you can change the non adjustable shiv (larger or smaller diameter) to adjust the RPM,s.
Need more ask. JIM
