ac evaporator

thanks for the reply 273 I went to ebay and found they make parallel and serpentine evaporators just like condensers . A parallel condenser is supposed to be 30% cooler( don't know I just read it) does that hold true for the evaporators? Am I wasting my time looking for a parallel evap. are they more efficient than serpentine evap for all I know there may be nothing wrong with mine except dirty. Jim
