Arrived on site for QC on 2 systems. Homeowner stated all was well with regards to normal system operation and did not have any questions for me. I begin my inspection at the outdoor units. I checked refrigerant pressures and found them both to be within manufacture specifications. I also checked all the wiring connections and did find a slightly loose connection in one of the disconnects. I was sure to make sure to tighten this down before proceeding further. Starting run amps look good on both units. I bubble tested the refrigerant lines to ensure good connections. and then proceeded to the indoor units and tested both drain lines and float switches. Both were working as intended. I also measured a 20° split from supply to return on both units. I verified all wiring connections on the indoor units. I tested amps on both blower motors and found them to be good. I also measured 20 A on all heat strips to ensure functionality. Units in good working order upon departure.
