OK.
the aux fan sounds like it's working right.
the a/c sounds like it's got the wrong oil charge... does the bill explain how much oil they put in? the shop flushed the condenser... did they flush the evap? did they replace the TXV? did they replace the compressor manifold? what refrigerant did they install? 12 or 134? what oil did they use? pag or ester or mineral? finally how much refrigerant did they use? the bill should state how many ounces were installed.
