This vicit was is a call back on a sealed system job I did on 11/1/23. Upon arrival I took low side pressure and it was sitting at a 5in vac. Couldnt do high side. FC tem is at 2F and RC is at 38F. The complaint is CX hears ringing and swooshing noises. To me the unit sounds like it is functioning normally bowever the compressor is making a loud ringing noise. Temp of compressor was warm/maybe a lil more at best. I tried moving all lines and condenser and nothing made this sound go away.Im not sure if the sound is coming from the lines inside of unit and just vibrating in the back. The swooshing noise is absolutely normal when refrigerant is moving through the lines. Called WPTL to document this appt to avoid any escalation with CX in future. Spoke to Adrian at WPTL.

"Replaced compressor and installed new drier. I did hear the whining noise and it went away once start device was pulled from compressor. After replacement of compressor and drier I presure tested with nitrogen and then vac'd down to 30in for 10mins. Equalized pressures and filled with 48g of R600a. Final low side pressure was at 12in vac. Informed CX to give unit a few hrs to get back to temps. This was not a cooling issue. Job is complete; ordrng 1 WPW10143759 (dryer FRVS), used 1 WPW10143759 (DRIER FRVS) from stock"
