Just been out eitg sub contractors to change an evaporator on A hubbard Cellar cooler changed to pressure tested and evacuated it run up after putting 134a in it and its scolding hot on the suction at compressor and cold on the other line. Its a seperate compressor reciever set from the condenser which is on the roof.

When compressor runs sounds awful and discharge pressure does not rise nor does suction? Seems odd

Think the compressor is done for as it stunk horrible when brazing the smell of the oil made my nose sting from all the pipework round system. As the clients being tight they just wanted evap changed but dont think that was a good idea.
