Prepaid maintenance on a 2013 train heat pump split system. Overall system is running OK I did find a weak capacitor on the outdoor unit. Replaced this capacitor it was a 40/5 µF. On the indoor unit the evaporator coil is starting to corrode a little bit. The filter dryer on the outdoor unit is corroding a little as well . Hard start system working normally the ultraviolet system is working normally the pan strip is not due to be changed. Educated homeowner on the few issues that I did find no action is needed at this time.
