AC too cold?

[davepl]

Hard to say because we had to run it indoors (it's like 40F out) to check the AC. After filling, the top tube on the evaporator under the hood (the tube that goes into the core) frosts up and turns white, so it's darn cold. But is that a symptom of too cold? Discharge air was 38F or something very chilly.

I just don't know a lot about AC and wonder if there's not an adjustment that's supposed to be made to prevent icing. If it's icing on the exterior, I worry about inside the housing.
