AC stopped working; dealer says condenser needs to be replaced on my dime.

I rarely use AC; whatever punctured my condensor did it when the system was off...no drama as you described. I went to use it one day and it didn't blow cold air...
Thanks, I'll see what the service guys say...

One option is to make the condenser (or radiator) bigger to compensate for the loss of air mass flow rate that a screen will produce. This then will obviously add to the weight of the car.
It's all about making the right compromises to arrive at an optimum design solution.
