What Direction Should the Fan Turn on an Outside A/c Unit?

A guy came over to fix my a/c and when I went out to check on him he said "I think you fan is turning the wrong way" and switched the direction. This makes no sense to me since it's been fine for years. Now I am concerned. It's possible he could have switched direction while installing a part and now had to switch it back to save face, but I'm concerned. The a/c runs fine, I just don't want it to burn out. It's running clockwise and air is blowing out the top of the sides.

The condenser fans pull the air through the coil which wraps around the unit andblows it out the top. When it is running you should be able to hold your hand above the fan and feel the warm air coming out.  I am concerned when you say that the air blowing out the top of the sides,this makes me think that the fan is blowing into the unit and forcing the air out through the condenser coil. The air conditioning will work until the outside temperature gets too high and fan cannot move enough air through the coil.

You can look at my articles on air conditioning to see if the condenser is working properly.
