    Depends. A lot of process chillers run year round so its just another quarterly PM. I like to brush tubes in the spring. Follow the manufacturers maint guidelines. If you have towers this is a good time to get them slicked up as well.

    On water cooled chillers, I change oil filter, Refrigerant filters, then leak test refrigerant side of chiller, go through starter tighten up all electrical then vacuum and clean all dust, dirt and etc. out. Calibrate controls. Brush condenser tubes, clean cooling tower clean strainer.

    if you guys are doing this during the spring start up...what are you doing during the winter shutdowns? i perform all of these types of maintenance during the winter so that any issues found can be taken care of before the spring.

    Alot of the same stuff. I also hit all the motors, check all bearings, go through the starters. Like you said, fish for winter work. Most of the machines I take care of are process so there isn't a real shut down for the season.
