Performed single system cooling maintenance. The system is from 2016. It has a rheem airhandler (2016) and Amana heat pump(2016). I checked amps, capacitor, filter, electrical, drains, safeties, and washed the outdoor unit. The system is cooling to manufacture specifications. I observed the 45/5 capacitor for the outdoor unit is starting to read low on the compressor side. This part is used to start the components on the outdoor unit.
