Upon arrival ken had stated that the outdoor unit was making a loud noise in the later part of the day and now it’s not. Turned system on and tested both first and second stage unit made no noise. I did pick up a slight rubbing noise coming from the bearings of the condenser fan motor. Disconnected compressor and ran just fan motor. When motor would cut off you can hear the rubbing. Amp draw was slowly creeping up as motor ran. Once the sun comes across that unit and heats the fan motor up the bearings start making the noise. Recommended replacing the condenser fan motor under warranty. Sent estimate to ken.
